The ALCHEMISTS WORKSHOP official Colloidal Glossary When only the best works, Why buy anything else but Alchemists Workshop Ultrafine Colloidals!

COLLOIDAL SILVER - Ions (positively charged) of silver dispersed in distilled water... COMPOUND - A chemically bonded combination of two or more different elements. Properties are distinct from those of the constituents. ELEMENTAL SILVER - The pure metal silver as in coins. HOLISTIC ALCHEMY - Treating the entire body as a whole; one living organism where the symptoms manifested can be caused by a problem elsewhere in the body, or mind. The use of electricity, water and precious and primal metals/minerals transmuted into .999 pure colloidals is a virutal act of alchemy. Thus Holistic Alchemy. ION - The smallest particle of an element and having a positive charge, thus making it reactive. PPM - Parts Per Million by weight of a mixture such as 5oz silver in 1,000,000 oz. water is 5 PPM. PRIMAL MINERAL - (Or Primal Metals) defined as non-precious but vital to life's existance. CELTIC SEA SALT - Salt from the Celtic Sea, containing many compounds besides the normal sodium chloride in table salt. SOLUTION - One material dissolved in another, such as salt in water. SUPER COLLOIDAL - When used together with Silver, Gold or Copper, it refers to a ppm of over 300 parts per million with tiny particle size of less than 0.005 micron. SUSPENSION - One material uniformly 'floating' in another. TROY OUNCE - Unit of weight for nobel metals. 12 Troy Ounces = 1 Pound. ULTRA-FINE - When used in conjunction with colloidals, it relates to the combination of the particle size of between 0.010 and 0.001 when taken together with the ppm. to provide a strong, pure, and effective collidal. EXTRACTS FROM MEDICAL AND SCIENTIFIC INSTITUTIONS AND PUBLICATIONS: Science Digest March 1978 "Silver, the Mightiest Germ Fighter" Silver kills over 650 disease-causing organisms, and resistant strains fail to develop. Silver is the best all-round germ fighter we have, and it is absolutely NON-TOXIC! Doctors report that, taken internally, it works against syphilis, cholera, malaria,diabetes, and severe burns.  ~ Richard L Davis executive director of the Silver Institute which monitors Silver technology in 37 countries, reports the following:- In four years we've described 87 important new medical uses for Silver"  ~ Karolinska Institute, Sweden. Dr Bjorn Nordstrom has used Silver in his cancer treatment method. He says his method is simple. It has brought rapid remission of patients given up on by other doctors. ~ FDA (USA Governing body) The FDA has stated that because Colloidal Silver is accepted as a pre-1938 Medicine. It may continue to be marketed in a letter dated September13th 1991 from Consumer Safety Officer, Harold Davis  ~ British Medical Journal "Colloidal Preparations of Silver in Pharmacy" February 1923. Pure Silver is entirely non-irritant. In tests at very high concentrations, it has been shown repeatedly that the rapidly exerted disinfectant action is of considerable therapeutic value. ~ Two Time Nobel Prize Winner, Dr. Otto Warburg 1933 Stated that: "Cancer is caused by the lack of oxygen and the fermentation sugars."  Two Time Nobel Prize Winner, Dr. Linus Pauling Ph D Stated, "You can trace every sickness, every disease, and every ailment to a mineral deficiency." Provo Herald February 13th 1992 (pg. D1) "Colloidal Silver as a remedy for AIDS."  Dr Robert Becker Author of "The Body Electric" Experiments conclude that Silver works on the full spectrum of pathogens without any side effects or damage to any part of the body, and that Silver was doing something more than killing disease organisms. It was also causing major growth stimulation of injured tissues. Dr. Becker discovered that all cancer cells, in the presence of Colloidal Silver, change back to normal cells. All strains of pathogens resistant to other antibiotics are killed by Colloidal Silver. " It kills even antibiotic resistant strains and also works on fungus infections. It stimulates bone-forming cells, cures the most common stubborn infections of all kinds of bacteria, and stimulates healing in the skin and other soft tissues". He also noted that healing of damaged tissues reportedly increased in excess of 50% the normal rate. Dr Becker made other astounding observations, amongst them was a correlation between Silver deficiencies and disease or the proper functioning of the immune system. In laboratory tests cancer cells were reverted back to normal, instead of being eliminated. Positive silver ions (Colloidal Silver) produced a new type of cell that had youthful characteristics similar to those found in young children's bone marrow. These new cells proliferated very quickly that have the ability to metamorphise into any type of cell the body needs it to become to repair damaged organs, bone or tissue; the effect is as apparent in people over 50 and poses the question as to whether this is a bodily process that is stunted or dormant when there is a deficiency of mineral silver and or positive silver ions. Michael Faraday. Physicist and experimental chemist (1791 - 1867) Made a small sealed glass vessel of Colloidal Gold. It has been kept till this day in the Museum at The Royal Institute in London, England. When the sealed glass vessel of Colloidal Gold is inspected to-day, utilizing a Tyndall-Faraday Ultramicroscope the tiny particles of gold are still suspended in motion. The motion is a continual random scattering movement. These Colloidal Gold particles have been moving continuously without stopping for approximately 150 years. This is the nature of colloidal particles. Dr. R. R. Rife MD. Gaston Nassons "The Galilee of the Microscope" by Christopher Bird. In the mid 1940s Dr. Rife made a very significant discovery universal to all virus, fungus, and bacteria pathogens. With a super powerful microscope that he developed himself, he observed bacterium change into fungus, followed after a period of time change again into a virus. and then again into a bacterium. He had discovered germs transmitted from one major microscopic life form to another and back again. The interesting thing to note is that irrelevant of the form these tiny evading enemies take they are vulnerable to suffocation from the catalytic action of Colloidal Silver Silver Education Coalition. Salt Lake City, Utah. Silver, in its many and varied Medical applications is unsurpassed in its effectiveness. It is a powerful, natural antibiotic prophylactic antiseptic, known anciently and at the turn of the century as an invaluable medication. Today Colloidal Silver is rapidly gaining favor in the medical community, and in home use too. It still causes no damage to the liver or kidneys or any other part of the body. In fact it accelerates healing. EPA. Environmental Protection Agency The agency's Poison Control Center reports no toxicity listing for Colloidal Silver, it is therefore considered harmless in any concentration. However all of the silver salts are identified as toxic and even then only resulting with Argyria (bluing of the skin). Therefore any concern should be with silver salts and compounds and NOT COLLOIDAL SILVER!

Submitted to Jubilee House November 18, 2001 USAID Purchase Order Number:      524-0-00-01-00014-5362 Extracts from Investigation Colloidal Silver Impregnated Ceramic Filter Report 2:  Field Investigations Daniele S. Lantagne Alethia Environmental 1    Project Background 1.1    Hurricane Mitch, USAID, and CACEDRF In October 1998, Hurricane Mitch devastated Central America, causing over 3,000 deaths in Nicaragua alone (USAID 2001, 2001a).  An estimated 18 percent of the population of Nicaragua was affected by Mitch, and water and wastewater systems serving 804,000 people suffered over US$560 million in damage.  The Unites States provided US$22 million in immediate humanitarian and food aid, and an additional US$8 million to start reconstruction activities in health, agriculture, and micro-finance. In May 1999, the United States Congress authorized US$621 million in aid under the Emergency Supplemental Appropriations Act (USAID, 2001).  These funds were authorized to support reconstruction in countries affected by Hurricanes George and Mitch, and were later authorized to cover Hurricanes Floyd and Lenny, as well as the earthquake of January 1999.  This appropriation created an account named the Central American and Caribbean Emergency Disaster Recovery Funds (CACEDRF). USAID is responsible for administering US$586.8 million of the US$621 million allocated under CACEDRF (USAID, 2001a).  Of the total funds, US$94.1 million was allocated for economic reactivation, public health, school rehabilitation, disaster mitigation, and municipal restoration in Nicaragua.  As of June 30, 2001, a significant amount of progress on projects relating to water supply and sanitation had already occurred (Table 1-1). Table 1ĭ:  CACEDRF Successes Relating to Water Supply and Sanitation in Nicaragua USAID is responsible for administering US$586.8 million of the US$621 million allocated under CACEDRF (USAID, 2001a).  Of the total funds, US$94.1 million was allocated for economic reactivation, public health, school rehabilitation, disaster mitigation, and municipal restoration in Nicaragua.  As of June 30, 2001, a significant amount of progress on projects relating to water supply and sanitation had already occurred (Table 1-1). Table 1ĭ:  CACEDRF Successes Relating to Water Supply and Sanitation in Nicaragua Category    Success Economic Reactivation 57,000 households incorporated environmentally sustainable practices on their farms 8,000 hectares of watershed area protected Public Health 2,440 wells rehabilitated or built 5,740 latrines constructed 600 seepage pits constructed 175 deep wells drilled in rural areas 10,000 training visits held to improve health behavior related to new water and sanitation infrastructure 6 health clinics constructed School Rehabilitation 196 schools scheduled for rehabilitation of wells and latrines Disaster Mitigation Cleaning and stabilizing stream channels Construction of drainage channels Municipal Restoration Projects with local governments on storm drain systems, flood control, river deck construction

An additional goal of the rehabilitation program in Nicaragua is to investigate point-of-use household water filtration systems (USAID, 2001b).  To this end, USAID worked to install 40,000 sand filtration units, supervised by Maria Alejandra Bosche.  Ms. Bosche found that follow-up education was critical to the correct and continued use of the filter system (Bosche, personal conversation). Secondly, USAID contracted with Jubilee House Community (JHC) to study the Potters for Peace (PFP) ceramic water filtration system.  JHC, an intentional Christian community, is a 501(c)3 organization in North Carolina (JHC-CDCA, 2001).  From 1979 – 1994, members of the community worked on shelters for homeless and battered women, as well as other social and justice issues, in North Carolina.  In 1994, the community moved to Nicaragua, established the Center for Development in Central America (CDCA), and began working with communities in Nicaragua.  After Hurricane Mitch, JHC-CDCA began to work on reconstruction projects in Nueva Vida, a nearby community swelled with displaced persons.  USAID provided funding and supplies to build housing, a medical clinic, and latrines (USAID, 2001c).  JHC and a group of volunteers worked with the community to build these facilities, in addition to a number of other projects.  One of these other projects is the promotion of the Potters for Peace water filtration system to provide safe drinking water for families in Nueva Vida. JHC worked with PFP to contract Daniele Lantagne, Principal of Alethia Environmental and Lecturer in Civil and Environmental Engineering at the Massachusetts Institute of Technology, to complete the project.  The project was divided into two deliverables, one addressing the intrinsic effectiveness of the filter, and the other addressing the performance of the filters under field conditions.  Specifically the reports are to address the following: Report 1:  Intrinsic Effectiveness of the Potters for Peace Ceramic Filter ·    Best practices for colloidal silver application. ·    Expected filter flow rates with and without colloidal silver. ·    Expected lifetime per application of colloidal silver. ·    Concentration of silver in filtered water. ·    Effects of ingestion of the silver. ·    Inactivation of microbes as a function of the concentration of silver. ·    Effectiveness of silver in removing other pollutants commonly found in the area of interest. Completion Deadline:  December 21, 2001 The PFP Filter Initial Filter Design In 1981 the InterAmerican Bank financed a comparative study designed to determine which of 10 appropriate technology filters could be best adapted to the objectives of the project, which were (ICAITI, 1994): 1.    to produce a domestic filter of suitable capacity; 2.    in a self-supporting manner; 3.    whose production would foster economic activity at low income levels; and 4.    foster artisan activity. ICAITI, an industrial research institute in Guatemala supported by the Organization for American States, was contracted to complete the research and to choose a model.  Ten models were evaluated based on filtration flow, bacteriological efficiency, ease of manufacture, availability of materials, final cost, contribution to artisan activity, and ease of distribution.  All but two models were discarded after initial review because they did not meet basic criteria.  The two models not discarded were: 1.     Lathed clay filter with feldspar, sawdust, and colloidal silver impregnation; and 2.     Lathed clay filter with sand, sawdust, and colloidal silver impregnation. None of the ten models investigated utilized chlorine as a disinfectant. Further research was then conducted on the two models that met the basic criteria.  This research, led by Fernando Mazareigos, did extensive bacteriological testing over a 3 to 10 month period.  Results of this research include: 1.    Of 302 filtered samples analyzed, only 6.3 percent were above 1.0 coliforms per 100 mL of water.  The method used for analysis was most probable number.     2.    Application of silver was determined to be more uniform when applied by brush as opposed to filtering water containing colloidal silver through the filtering element. 3.    Frequent contamination was found both in the first few runs of the filter (41 percent contaminated) and after handling the element during sampling.  This was attributed to handling the filter and ICAITI recommended that users refrain from touching the element during its useful life.  Due to the omnipresent bacteria in the environment “usage of the filter must be accompanied by sanitary and hygienic practices in order to maximize the potential benefits to health.” 4.    Flow in the filters gradually declined from 3.5 liters per hour on Day 1 to 1.97 liters per hour on Day 365.  The report contained no information on turbidity of the raw water supply. 5.    ICAITI recommended not using the filter with chlorinated water.  No reason was given. Based on these results, ICAITI concluded that a colloidal silver impregnated ceramic filter was the only design that met all established criteria of the study.  The United Nations then included this filter in their Appropriate Technology Resource Material Manual.  ICAITI concluded its study by producing a 'Manual Para La Fabricacion De Filtros Artesanales De Agua Potable.'

The microorganisms that cause these waterborne diseases are classified as bacteria, protozoa, viruses, and helminths (Levinson, 1996).  These four organisms belong to different kingdoms and are eukaryotic (containing DNA with a nuclear membrane), prokaryotic (without a defined membrane), and noncellular (Table 3-2). Table 0Į:  Biologic Relationships of Pathogenic Microorganisms (Levinson, 1996) Kingdom    Pathogenic Microorganism    Type of Cell Animal    Helminths    Eukaryotic Protist    Protozoa Fungi    Eukaryotic Eukaryotic Prokaryote    Bacteria    Prokaryotic     Viruses    Noncellular   Bacteria are single-celled prokaryotic (without nucleus) members of the eubacteria group (MEI, 1991).  Although they are not eukaryotes (with a defined nucleus), they have similar cell chemistry to eukaryotes.  Their size varies from 0.3 to 100 μm in length, depending on their shape (Table 3-3).   E. coli is a rod shaped bacteria that is 0.5 μm in width and 2 μm in length.  Most of the bacteria are larger than the 1μm pore size that Potters for Peace aims to maintain in their filter. Table 0į:  Bacteria Types and Size (adapted from MEI, 1991) Shape    Name    Size Spherical    cocci, coccus    1 – 3 μm in diameter Rod    bacilli, bacillus    0.3 – 1.5 μm in width 1.0 – 10 μm in length Curved rod    vibrios    0.6 – 1.0 μm in width 2 – 6 μm in length Spiral    spirilla    up to 50 μm Filamentous        up to 100 μm and longer   Protozoa are single-celled eukaryotic (with a nucleus) organisms.  They feed on bacteria and other microscopic organisms.  Giardia lamblia and cryptosporidium are common disease-causing protozoa.  Protozoa range in size from 8 – 100 μm. Viruses are parasitic particles consisting of a strand of genetic material.  They do not have the ability to synthesize new compounds, and instead invade the host cell and redirect the host genetic material to produce viral particles.  Because they do not have the structure to reproduce themselves, viruses are the smallest of the disease-causing organisms, at 0.02 – 0.2 μm. Helminths are worms that are part of the animal kingdom.  Platyhelminthes (flatworms) and Aschelminthes (flukes, tapeworms) are present in water bodies throughout the world, and enter the human body to cause diseases such as trichinosis, hookworm, and roundworm infestation. Infectious agents commonly found in drinking water include members of the bacteria, virus, protozoa, and helminth groups and cause diseases ranging from diarrhea to jaundice to acute respiratory illnesses (Table 3-4).

To date, no studies have been completed analyzing the pore size of the PFP filter.  For Report 1 of this study (December 2001), analysis of the pore size of the PFP filter and retention rates of selected viruses and protozoa will be completed. The second inactivation mechanism for organisms contributing to waterborne disease utilized in the PFP filter is COLLOIDAL SILVER.   Colloidal Silver as a Disinfectant Silver is a soft, malleable metal, which is stable in water and oxygen but attacked by sulfur compounds in air to form a black sulfide layer (CRC, 1997).  The atomic number of silver is 47, its atomic weight is 107.868, and it exists in its common valence states of Ag+, Ag2+, and the mineral form of argentite, Ag2S.  Typical ambient concentrations of silver are presented in Table 4-1.  Silver is present throughout the environment in small concentration (milligram to nanogram), but is not essential for animal or plant life. Table 0ĭ:  Typical Ambient Concentrations of Silver (adapted from CRC, 1997) Content    Concentration Total Content in Soils    0.03 – 0.9 mg/kg Soluble Content in Soils    0.01 – 0.05 mg/kg in 1 N NH4AOC Content in Sea Water    0.04 μg/kg Content in Fresh Water    0.13 μg/kg Content in Marine Animals    3 – 10 mg/kg Content in Humans    Blood:    < 2.7 μg/L Bone:     1.1 mg/kg Liver:     <5 – 32 ng/g Content in Animals    6 μg/kg Content in Plants    0.01 – 0.5 mg/kg Content in Common Foods    0.07 – 20 mg/kg Essentiality    Plants:      no Animals:   no The daily dietary intake by humans is estimated at 0.0014 to 0.08 mg (CRC, 1997).  When the maximum CRC intake per day (0.08 mg) is calculated over a 70-year lifetime, a total of 2.0 grams of silver are ingested per person per lifetime. 0.08 mg / day   365 days / year  70 years = 2.0 grams / lifetime    Toxic intake for humans is 60 milligrams, while a lethal intake is 1.3 to 6.2 grams (CRC, 1997). Silver Human Health Standards and Regulations World Health Organization (WHO) In their Guidelines for Drinking-Water Quality, 2nd Edition (1993), the WHO addressed human health effects of silver and guidelines values to prevent those effects. WHO determined that: 1.    The retention rate of silver in humans and animals is only 0 – 10 percent.  The retained silver is mainly stored in the liver and skin.  The half-life of silver in the liver is 50 days. 2.    Silver is occasionally found naturally in ground and surface water at 5 μg/L. 3.    Average human intake of silver is 7.1 μg/day. 4.    The acute lethal dose of silver nitrate is a minimum of 10 grams. 5.    Argyria is the only known human health effect of silver, and “is a condition in which silver is deposed on skin and hair.” Based on their research, the WHO recommended a guideline value for silver of 10 grams per lifetime.  This is a NOAEL (no observed adverse exposure limit) standard.   WHO concludes by stating “as the contribution of drinking-water to this NOAEL will normally be negligible, the establishment of a health-based guideline value is not deemed necessary.”   In 1996, the WHO reiterated this determination by designating silver as a “U” compound.   “It is unnecessary to recommend a health-based guideline value for these compounds [U compounds] because they are not hazardous to human health at concentrations normally found in drinking-water.” However, the WHO addresses the fact that silver is often used as a disinfectant, and in such cases, “the daily intake of silver from drinking-water can constitute the major route of oral exposure.”    Thus, WHO has established an additional guideline value for when silver is “used to maintain the bacteriological quality of drinking-water.”  This guideline states “higher levels of silver, up to 0.1 mg/L (this concentration gives a total dose over 70 years of half the human NOAEL of 10 g) could be tolerated in such cases without risk to health.” Thus, the guideline value appropriate for use in analyzing the PFP filter is 0.1 mg/L (or 100 μg/L) in the finished, filtered water.   United States Environmental Protection Agency (USEPA) The USEPA has also investigated silver to determine appropriate drinking water standards.  The USEPA recommends a maximum intake of 5 μg/kg/day (1996).  In the average 70 kilogram adult, this is equivalent to 350 μg/day.  This recommendation was established to prevent argyria, “a medically benign but permanent bluish-gray discoloration of the skin.  Argyria results from the deposition of silver in the dermis and also from silver-induced production of melanin.”   Argyria is “more pronounced in areas exposed to sunlight due to photoactivated reduction of the metal”, and “although the deposition of silver is permanent, it is not associated with any adverse health effects.”   In addition, “no evidence of cancer in humans has been reported despite frequent therapeutic use of the compound over the years.”  Silver was used for centuries to treat syphilis, and as an astringent in topical preparations.  The 2001 National Secondary Drinking Water Regulations recommends a maximum silver concentration of 0.10 mg/L (or 100 μg/L), but specifically states that “EPA recommends secondary standards to water systems but does not require systems to comply.  However, states may choose to adopt them as enforceable standards.”  These secondary non-enforceable guidelines regulate “contaminants that may cause cosmetic effects or aesthetic effects in drinking water.”  The USEPA does not address separate standards for use of silver as a disinfectant.   It is of note that the USEPA secondary standard is the same as the WHO guideline value for use of silver as a disinfectant:  0.1 mg/L or 100 μg/L.

The USEPA has also investigated silver to determine appropriate drinking water standards.  The USEPA recommends a maximum intake of 5 μg/kg/day (1996). In the average 70 kilogram adult, this is equivalent to 350 μg/day. This recommendation was established to prevent argyria, a medically benign but permanent bluish-gray discoloration of the skin. Argyria results from the deposition of silver in the dermis and also from silver-induced production of melanin. Argyria is more pronounced in areas exposed to sunlight due to photoactivated reduction of the metal”, and “although the deposition of silver is permanent, it is not associated with any adverse health effects. In addition, no evidence of cancer in humans has been reported despite frequent therapeutic use of the compound over the years. Silver was used for centuries to treat syphilis, and as an astringent in topical preparations. The 2001 National Secondary Drinking Water Regulations recommends a maximum silver concentration of 0.10 mg/L (or 100 μg/L), but specifically states that “EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards.”  These secondary non-enforceable guidelines regulate contaminants that may cause cosmetic effects or aesthetic effects in drinking water. The USEPA does not address separate standards for use of silver as a disinfectant.   It is of note that the USEPA secondary standard is the same as the WHO guideline value for use of silver as a disinfectant: 0.1 mg/L or 100 μg/L. Colloidal Silver and USFDA/USEPA Regulation A colloidal solution is a true solution that consists of colloidal macromolecules and solvent and that is thermodynamically stable and readily reconstituted after separation of the macromolecules from the solvent (Stenesh, 1996).”  Furthermore, a colloid is a macromolecule or a particle in which at least one dimension has a length of 10-9 to 10-6 meters. Thus, colloidal silver is a stable solution of very small silver particles suspended in distilled water or proteins. Higher concentrations of colloidal silver (such as used by PFP) are suspended in proteins because they would not be stable in water (Quinto, personal conversation). In 1999, the United States Food and Drug Administration (USFDA) issued a ruling that all over-the-counter (OTC) drug products containing colloidal silver ingredients or silver salts for internal or external use are not generally recognized as safe and effective and are misbranded. FDA is issuing this final rule because many OTC drug products containing colloidal silver ingredients or silver salts are being marketed for numerous serious disease conditions and FDA is not aware of any substantial scientific evidence that supports the use of OTC colloidal silver ingredients or silver salts for these disease conditions (Federal Register, August 17, 1999). The burgeoning naturopathic market for colloidal silver in the United States prompted this ruling. In a cease-and-desist letter issued to Mr. Randy Winters, the USFDA quoted Mr. Winters’ web site as stating, colloidal silver has been proven to be useful against over 650 diseases, including cancer, without any known harmful side effects. It has been found to cause rapid regeneration of damaged cells and tissues, subdue inflammation and promote faster healing (FDA, 2000). A simple web search for “colloidal silver leads to numerous sites advertising unsubstantiated healing properties, and another set of sites selling home-based colloidal silver generation machines. On August 8, 2001, I spoke with Ms. Roma Egli, the colloidal silver contact person at the USFDA, about the PFP filter and the use of colloidal silver for disinfection. Ms. Egli said that the USFDA does not deal with disinfection agents, and that the USEPA would regulate the use of colloidal silver in this manner. As long as PFP does not state that the filters are treating animals or humans for disease, and does not state that the colloidal silver is an antibiotic, the product is not regulated under the USFDA. She also mentioned that colloidal silver is used for water disinfection on transportation systems such as airplanes, trains, and boats. When asked, Ms. Egli did state that she has seen argyria cases in people only using naturopathic colloidal silver. No case she has seen is as severe as Rosemary Jacobs, but she has seen permanently blue fingertips. Overall, Ms. Egli expressed the viewpoint that the USFDA is concerned about labeling of colloidal silver as a medical drug when there is no research to support such claims. They are not concerned with colloidal silver as a disinfectant, and in fact Ms. Egli recommended that I talk with the Silver Institute (a promoter of colloidal silver as an antibiotic) about purchasing a generator to make colloidal silver in Nicaragua rather than importing it from Mexico. Because the generators are only capable of producing colloidal silver in the ppm range, as opposed to the 3.2 percent solution that PFP uses, this idea was determined to be not appropriate for PFP . XXXXXXXXXXXXXX I then spoke with Wade Travathan, of the USEPA, about colloidal silver as a disinfectant. The EPA Office of the Pesticide Program regulates disinfectants because microorganisms in the United States are legally classified as pests. Thus, any product that kills microorganisms is classified under federal law as a pesticide. Mr. Travathan said that there are current, active products that are registered with EPA that use colloidal silver as a disinfectant. To become registered as a pesticide, you submit data that details toxicity and efficacy. You can refer to data that has already been submitted by another company, by offering that company appropriate compensation. The submission forms are available on the web site and submission is free of charge. However, there is a maintenance fee of US$1,000 dollars per year on your permit. The Office of the Pesticide Program can be reached at www.epa.gov/pesticides. Thus, with the appropriate permitting from the USEPA Office of the Pesticide Program, and data supporting that the finished water concentration of silver is less than the USEPA secondary standard of 100 μg/L, a colloidal silver impregnated filter is a legal product to distribute and use in the United States and meets all USA regulations. Silver in Ceramics Potters for Peace is not the only organization to use silver as a disinfectant in ceramic filtration units. Basu (1982) in India soaked ceramic candle filters with a pore size of 6 – 31 microns, and a filtration rate of 3 - 4 liters per hour, in silver salts. Filtered water with this system was bacteria-free. Basu chose silver over gold as the bacteriocide, and also tested candle filters with finer pores that would capture the bacteria. The filtration rate was so slow with these finer pores, however, that the filters were “not of much practical value. Thus a larger pore size, combined with a disinfectant, is of more practical value because the flow rate is high enough to provide enough water for a family. Mechanisms of Action of Silver Russell (1994) details the historic uses of silver, beginning with Aristotle advising Alexander the Great to boil water and store it in silver or copper vessels to prevent waterborne disease on his campaigns. In 1869, Ravelin reported that silver exerted its antimicrobial effect at very low concentrations, an effect with was later termed "oligodynamic" or "active with few" (Russell, 1994). In 1881, Crede advocated silver to prevent eye infections in newborns, and silver drops were used to prevent gonorrhea of the eye in newborns until very recently. In 1920, the microbiological action of silver was determined to be due to the Ag+ ions formed by tarnishing, surface-oxidation, or electrical activation. Today, silver is more commonly used as a drinking water and swimming pool disinfectant in Europe than in the United States (Russell, 1994). Studies have shown that silver can be used when chlorine is present for additional disinfection.  Argyria, first reported in 1647, is less common today but is still reported. Three main mechanisms are responsible for bacterial inactivation with silver (Russell, 1994): 1. Silver reacts with thiol (sulphydryl, SH) groups in the bacterial cell a.In structural groups   b.In functional (enzymic) proteins 2.Silver produces structural changes in bacterial cell membranes 3.Silver interacts with nucleic acids These three mechanisms are described in further detail in the following sections.  Although it is unknown at this time which of these mechanisms is predominant in the PFP filter, laboratory data clearly shows that PFP filters impregnated with colloidal silver remove 99 – 100 percent of bacteria (CIRA-UNAN, various dates). Further information on the mechanism of action of colloidal silver in the filter and data on laboratory tests on the filter are presented in Report 2 (December 2001). Heinig's research on silver deposited on an inert surface is of special note in relation to the PFP filter. Heinig (1993) showed silver on a large inert surface area exhibited a strong catalytic reaction with oxygen, which resulted in strong bactericidal activity.  The factors controlling the rate of the catalytic reaction were:  the size and dispersion of the silver on the surface area of the bed, and the volume of oxygen in solution. Heinig found that bacteria and viruses were killed on contact without the need for the release of metals into the water. Silver as an Enzyme Inhibitor Living cells are characterized by a complex and beautifully organized pattern of chemical reactions mediated and directed by enzyme systems (Webb, 1963). Webb continues by describing the theory of inhibiting enzymes as a means to understanding the “energetics of the cell. Directly distorting the pathways of enzymically directed reactions by the introduction of a chemical substance is one approach amongst others to alter metabolic activity. Other ways to alter metabolic activity including changing the temperature or the pH, by irradiation of high pressure, are nonspecific and seldom does one have any idea as to exactly what is occurring in the complex protoplasmic matrix. If one had to choose the most interesting and important characteristic of enzyme inhibitors, what it is that makes them one of the most powerful tools in so many fields of biological investigation, it would be their relative specificity. The more we know about the exact nature of the perturbation produced and the more selective this action can be made, the more likely it is that clear interrelationships will emerge and the goal of understanding the energetics of the cell be achieved. A number of metals are known to inactivate the SH (sulfur-hydrogen, or sulfhydryl, or thiol) bond in enzymes. Silver is widely used in biochemistry applications to determine if an enzyme has a SH group as part of its functional structure. Webb's summary of data collected on the action of silver on the SH bond shows extremely varied inactivation depending on specific enzyme and concentration (Table 4-2)These different reactivities could be attributed to an electric field surrounding the SH group, steric factors depending on where the SH group is in the protein structure, occurrence of disulfide linkages, complexes of the SH group with surrounding groups, and whether there is a single or double SH group. Other SH inhibitors studied include mercury, arsenite, cadmium, iodine, ferricyanide, and permanganate. Although there exists a large variation, SILVER clearly inactivates certain enzymes in sources that are responsible for waterborne disease (Table 4-2).  Waterborne disease sources are boldfaced in Table 4-2.
