1. Studies document that Florida Saltwater fish, shellfish, and freshwater fish have high
levels of mercury in large parts of the state.

2. There are fish consumption warnings/limits for king mackerel and shark in all parts of the state and consumption warnings on jack crevalle, spotted sea trout, Spanish mackerel, gafftopsail catfish, and lady fish in some areas.

3. Five Gulf saltwater species have average mercury levels on tested samples higher than the FDA/EPA action level for fish; 27 species have average mercury test levels above the FDA warning level for mercury in fish with some above the action level, and 16 species of fish as well as crabs, oysters and shrimp have average test levels near the warning level or some tested above the FDA action level.

4. Studies have found that people who eat Gulf Coast fish at least once per week usually
have dangerous levels of mercury. 29% of a coastal sample ate fish at least once per week.
Studies have found adverse health effects for those who eat fish at below the FDA warning level.

5. Studies have found that fish and shellfish that feed near offshore oil and gas platforms
have higher levels of mercury than other areas.

6. Studies have found that freshwater predator fish such as bass, pickerel, and bowfin have high levels of mercury in most of the state, with fish consumption warnings issued. 8 other species have average test levels near the warning level or some tested above the FDA action level.

7. Studies have found that predator species such as wading birds, alligators, and Florida Panthers whose diet depends on fish have high levels of mercury, and adverse health and reproductive effects.

8. Studies by the Oak Ridge National Laboratory(ORNL) have found high levels of dangerous forms of mercury in landfill gas being emitted from Florida landfills and from lands where sewer sludge is spread, due to methylation of mercury to methyl and dimethyl mercury by soil bacteria.

9. All sewer plants and sewer sludge in Florida have dangerous levels of mercury , which is a major source of mercury in fish and source of mercury in crops and rain where sewer sludge is spread. High levels of mercury are being found in rain throughout Florida and the U.S., including methyl mercury from landfills and land spreading. The most common source of these high mercury levels was found to be human excretion into home and business sewers from those with amalgam dental fillings.

10. The National Academy of Sciences found that 50% of U.S. infants have significant developmental effects such as ADD, dyslexia, mood or anxiety disorders, learning disabilities, eczema, asthma, or other chronic allergies or health problems. Studies document that the majority of these are due to toxic exposures, with the most common and significant being mercury.

11. The 3 main sources of mercury in Florida infants are mercury thimerosal in vaccinations; mercury from mother’s amalgam dental fillings transferred across the placenta to the fetus or through mother’s milk to the infant; and mercury from fish. These are all significant sources in Florida.

12. The U.S. CDC and National Academy of Sciences found that at least 10% of U.S. women
have mercury levels high enough to cause developmental neurological conditions in
prenatally exposed infants; this may be higher in Florida due to higher than average
mercury levels in fish and high levels of fish consumption. The tests used mainly measured methyl mercury, and did not fully assess exposure levels from dental amalgam or infant vaccinations, which are
the largest sources in infants.

13, Mercury exposure is cumulative from the various sources and bioaccumulates over time, with different sources more significant in different individuals. Health effects are synergistic between the different forms of mercury exposure and other toxic exposures, and depend also on individual susceptibility which varies widely- due to immune reactivity and systemic detoxification differences of individuals.

Documentation:
Mercury is one of the most toxic substances commonly encountered, and according to Government agencies causes adverse health effects in large numbers of people in the U.S.
[1,14-16,20,21] Based on widespread tests, the U.S. CDC estimates that approx. 10 % of women of childbearing age, 6 million women, have current mercury levels that would put fetuses at risk of developmental neurological problems(14), without considering other common sources of mercury in infants. Studies by the National Academy of Sciences have found that 50 % of U.S. children have significant developmental conditions such as ADD, dyslexia, autism, learning disabilities, mood or anxiety disorders, eczema, asthma, chronic allergies, etc.(8), and studies have also documented that the majority of these are caused by toxics exposures, with mercury exposures being one of the most common and significant of these(8,14,15,20,21b,27).

The extreme toxicity of mercury can be seen from documented effects on wildlife by very low levels of mercury exposure. The amount of mercury in the marine environment is increasing 4.8% per year, doubling every 16 years(6). A major factor in the extreme decline of wading birds in Florida is mercury exposure from eating fish and other fish predators are affected as well(7). Some Florida panthers that eat birds and animals that eat fish containing very low levels of mercury(about 1 part per million) have died from chronic mercury poisoning(7). Since mercury is an estrogenic chemical and reproductive toxin, many of the rest cannot reproduce. The average male Florida panther has higher estrogen levels than females, due to the estrogenic properties of mercury(7). Similar is true of some other animals at the top of the food chain like polar bears, beluga and orca whales, and alligators, which are affected by mercury and other hormone disrupting chemicals.

Studies document that Florida Saltwater fish and shellfish have high levels of mercury in large parts of the state(4,5,9,12,3b). There are fish consumption warnings/limits for king mackerel and shark in all parts of the state and consumption warnings on jack crevalle, spotted sea trout, Spanish mackerel in several estuaries, and on gafftopsail catfish, and lady fish in Tampa Bay (4,9). Some areas such as North Florida Bay and offshore Tampa Bay have test levels higher than most other areas(4).

Based on the tests that have been done, five saltwater species(king mackerel, black grouper, florida smoothhound, great while shark, tilefish) have average mercury levels on tested samples higher than the FDA/EPA action level of 1 part per million(ppm) for fish(4,5,12); 17 species have average mercury test levels above the FDA warning level(0.5 ppm) for mercury in fish(barracuda, black drum, blacktip shark, bluefish, bonefish, bonnethead shark, bull shark, cobia, snook, greater amberjack, jack crevalle, ladyfish, lemon shark, red drum,rock bass, spanish mackeral, spotted bass, stone crab) , and 16 species of fish(blacknose shark, blue crab, gafftopsail catfish, gag grouper, grouper spainish, gulf flounder, permit, red grouper, sand trout, sheepshead, silver seatrout, southern flounder, tarpon, tripletail, white bass, yellow bass, yellow jack), as well as crabs, oysters and shrimp have average test levels near the warning level or some that tested above the FDA action level(4,12). Studies (5) have also found that the level in most large predator species on the Gulf Coast is higher than levels found to adversely affect health(25) with mercury contamination being pervasive along the whole coastal area, and that people who eat Gulf Coast fish at least once per week usually have dangerous levels of mercury(5). 29% of a coastal sample from Florida, Alabama, and Mississippi ate fish at least once per week(5).

The Mobile Register studies(5) have also found that fish and shellfish that feed near offshore oil and gas platforms have significantly higher levels of mercury than other areas(5) due to mercury used in drilling. Over 200 tons of mercury has been added to the Gulf through drilling over the last 30 years. More fishing occurs near such platforms since shellfish and fish tend to congregate in such areas. Other known major sources of mercury throughout the coastal area are air emissions and sewer outfalls, with some other large local industrial sites such as chlor-alkali plants(16).

The U.S. FDA recommends that pregnant women entirely avoid eating shark, swordfish, king mackerel and tilefish(10), because a significant portion of these types of fish have mercury levels above the FDA action level of 1 ppm. However other studies(25) including one by the National Academy of Sciences(14) have found the old FDA action level of 1 ppm is obsolete and not adequate to protect the public, as adverse effects have been found for those eating fish at least once per week at average mercury levels below the FDA warning level of ½ ppm.

Based on this a coalition of organizations using the name Environmental Working Group(EWG) did a large study to more fully assess mercury exposure effects and safety limits(12). In addition to the FDA limits, EWG advises pregnant women, nursing mothers and all women of childbearing age, should not eat tuna steaks, sea bass, oysters from the Gulf Coast, marlin, halibut, pike, walleye, white croaker, and largemouth bass(12). And that these women should eat no more than one meal per month combined of canned tuna, mahi-mahi, blue mussel, Eastern oyster, cod, pollock, salmon from the Great Lakes, blue crab from the Gulf of Mexico, wild channel catfish and lake whitefish. The EWG analysis was based on 56,000 test results on mercury in fish from 7 different government agencies, and toxicity studies by U.S. CDC and National Academy of Sciences.

However EWG recognizes that fish is an important health food with nutrients and essential fatty acids hard to substitute from other sources. The following fish are safer choices for avoiding mercury exposure: farmed trout or catfish, shrimp, fish sticks, wild Pacific salmon, croaker, haddock, some varieties of flounder, and blue crab from the mid-Atlantic. (12)

Studies have found that freshwater predator fish such as bass, pickerel, and bowfin have high levels of mercury in most of the state, with fish consumption warnings issued(3,4). Eight other species (alligator gar, black crappie, white crappie, blue catfish, flathead catfish, brook trout, drum, striped bass) have average test levels near the FDA warning level or some tested above the FDA action level(4). Studies have found that predator species such as wading birds, alligators, and Florida Panthers whose diet depends on fish have high levels of mercury, and adverse health and reproductive effects(7). The most vulnerable groups to mercury exposure are women who are pregnant or might become pregnant, nursing mothers, and young children(8,11,12,20,27). These groups should limit consumption of freshwater fish to no more than one meal per week (6 ounces of cooked fish for adults and 2 ounces of cooked fish for young children).

High levels of mercury including the very toxic organic forms are being measured in rainfall throughout the U.S.(24) High levels of the extremely toxic di-methyl and methyl mercury forms of mercury are being found in landfill gas coming from landfills and appear to be a source of some of this(22-24). Bacteria in landfills and in soils where sewer sludge is spread have been found to be methylating elemental and inorganic mercury to the organic forms(22,23). Government studies have found that all sewers in the U.S. and all sewer sludge have high levels of mercury, with the most common significant source being excreted mercury into sewers from those with amalgam dental fillings(13,23,26,21). Dental amalgam waste and mercury from human sewer sludge are major sources of mercury in some landfills and sludge is also used in landspreading on farms and other areas. Programs are already being implemented to reduce most other sources of mercury into sewers and into landfills such as flourescent light tubes. High levels of mercury have been found to be taken up in crops on land where sludge is spread(23), and high levels of emissions of elemental and organic mercury forms methylated by soil bacteria. Health Canada and Canadian sewer agencies have also documented similar information on mercury emissions from amalgam waste and sewer sludge to waterways, crops, and air(26), and have implemented standards and restrictions to help alleviate this problem.

Recent government studies have documented that the environmental effects of mercury excreted into sewers from those with amalgam dental fillings are widespread and significant, and are affecting everyone in Florida(22-26). The average amalgam filling has more than ½ gram of mercury, and has been documented to continuously leak mercury into the body of those with amalgam fillings due to the low mercury vapor pressure and galvanic current induced by mixed metals in the mouth. Because of the extreme toxicity of mercury, only ½ gram is required to contaminate the ecosystem and fish of a 10 acre lake to the extent that a health warning would be issued by the government to not eat the fish[2]. Over half the rivers and lakes in Florida have such health warnings[3,4] banning or limiting eating of fish, and most other states and 4 Canadian provinces have similar health warnings(6,26) Wisconsin has fish consumption warnings for over 250 lakes and rivers(6,13) and Minnesota even more, as part of the total of over 50,000 such lakes with warnings(6), 20% of all U.S. lakes and 7% of all U.S. river miles. All Great Lakes as well as many coastal bays and estuaries and large numbers of salt water fish carry similar health warnings.

Unlike many European countries and Canada(26) which have more stringent regulation of mercury that require amalgam separators in dental offices, the U.S. does not and most dental offices do not have them. The discharge into sewers at a dental office per dentist without amalgam separators is approximately 270 milligrams per day(18). For the U.S. this would be approximately 5400 kg/yr (or slightly over 6 tons/year of mercury into sewers and thus into streams and lakes in most cases. In Canada the annual amount discharged is about 2 tons per year, with portions ending up in waters/fish, some in landfills and cropland, and in air emissions. The recently enacted regulations on dental office waste are expected to reduce emissions by at least 63% by 2005, compared to year 2000 levels(26).

A study in Michigan estimated that dental mercury is responsible for approximately 14 % of mercury discharged to streams(18). Other EPA and municipal studies(18,13) found that dental office waste was responsible for similar levels of mercury in lakes, bays, and streams in other areas throughout the U.S. Another Canadian study found similar levels of mercury contribution from dental offices into lakes and streams(26). Surveys of dental office disposal practices found the majority violated disposal regulations, and dangerous levels of mercury are accumulating in pipes and septic tanks from many offices(18,26).

The total discharge into sewers from dental amalgam at individual homes and businesses is even more than at dental offices, since the average person with several amalgam fillings excretes in body waste approx. 100 micrograms per day of mercury(17,19,21). This has also been confirmed by medical labs(13c) such as Doctors Data Lab in Chicago and Biospectron in Sweden which do thousands of stool tests per year and is consistent with studies measuring levels in residential sewers by municipalities(13b). The reference average level of mercury in feces(dry weight) for those tested at Doctors Data Lab with amalgam fillings is 0.26 milligrams/kilogram, compared to the reference average level for those without amalgam fillings of .02 mg/kg(ppm). In the U.S. this would amount to approximately 7300 kilograms per year into sewers or over 8 tons per year. Thus the amount of mercury being excreted from dental amalgam is more than enough to cause dangerous levels of mercury in fish in most U.S. streams into which sewers empty. However it should be remembered that the largest sources of mercury air emissions are coal power plants and incinerators, with additional significant contributions from power plants burning bunker oil, and these are also significant sources of mercury in Florida’s streams, lakes, and bays(16). Since only ½ gram of mercury is required to contaminate all fish in a 10 acre lake to dangerous levels requiring health warnings(2), all of these sources need to be reduced to result in fish safe to eat.

Oak Ridge National Laboratory (ORNL) studies have also documented high levels of mercury in sewers and sewer sludge(23). According to an EPA study the majority of U.S. sewerage plants cannot meet the new EPA guideline for mercury discharge into waterways that was designed to prevent bioaccumulation in fish and wildlife due to household sewer mercury levels(13). Over 3 tons of mercury flows into the Chesapeake Bay annually from sewer plants, with numerous resulting fish consumption advisories for that area and similar for other areas(6). The EPA discharge rule is being reevaluated due to a National Academy of Sciences report of July 2000 that found that even small levels of mercury in fish result in unacceptable risks of birth defects and developmental effects in infants(14).

Thousands of peer-reviewed studies have documented that amalgam dental fillings, in addition to being a major source of mercury in the environment and fish, are also the number one source of mercury in most people with several fillings, with exposure levels above Government health guidelines(21). The Gov’t health guideline(MRLs) for mercury(15) of 0.2 micrograms per kilogram body weight per day for organic mercury result in limits of approx. 6 micrograms per day for a 44 pound child, 16 ug/d for a 115 pound adult, and 24 ug/day for a large adult. The corresponding MRL for mercury vapor(the type emitted by amalgam) is 0.2 micrograms per cubic meter of air breathed which results in a limit of about 6 ug/d for a large adult and less for a child. These levels are commonly exceeded in people with several amalgam fillings(21) and in those who regularly eat seafood with mercury levels commonly found in Florida fish (4, 5,12,etc.). Thousands of peer-reviewed studies also document that mercury causes over 30 chronic neurological or immune related health conditions(21,20,27), from which thousands are documented to have recovered or significantly improved after proper treatment of mercury toxicity(21b, Section VI, 20).
