“…In a 1983 study, 5 varieties of canned fish sold in Port Moresby, Papua New Guinea, were examined for total mercury and methylmercury content (Kyle and Ghani, 1983). The average concentration of total mercury in 38 samples of canned tuna (unspecified) was 0.45 ppm.…”

Mercury is a toxic heavy metal released into the environment from both natural and anthropogenic sources. It is of great interest to consumers as to whether it can cause neurological effects at low dose levels. The effects of organic mercury exposure at high levels have been demonstrated in several large-scale poisonings, particularly those in Japan and Iraq in the 1950s, '60s and '70s. These epidemics showed that organic mercury, in sufficient concentrations, is a potent neurotoxin that is especially harmful to the developing nervous system. Since the most common form of human exposure to organic mercury is through fish consumption, several epidemiological studies have examined the relationship between maternal fish intake and health effects in humans, especially the fetus.Levels of mercury in fish vary depending on factors such as: trophic level in the food chain, size, and habitat location. For this reason, it is important to gather information on mercury levels in different types of fish in various parts of the world. Results of recent studies have caused the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) to issue new advisories on the fish consumption Rosalee S.

However, there is concern that other individuals will significantly reduce their fish consumption also, thereby decreasing the potential health benefits of seafood. This review is meant to promote understanding of current issues regarding mercury in seafood and provides a compilation of up to date information on the following topics: background information on mercury; large scale mercury poisonings; epidemiology studies and risk assessment; and studies on mercury in tuna in different geographical locations.

“…Different levels of mercury in blood have been reported in studies of people residing in different parts of the world. Some of the differences have been attributed to the natural abundance of mercury and, as a result, the high levels of mercury in food sources for local people (Kyle & Ghani 1983). The results here show that the total mercury content in maternal blood (15.4 ___ 5.8/zg1-1) was much higher than in Europeans (5.3 ___ 0.9/zg1-1) (Commission of the European Communities 1990) but lower than in Japanese women (19 _ 3.6 txg1-1) (Ong et al 1985).…”

Concentrations of heavy metals in maternal and umbilical cord blood

et al. 1993

Concentrations of lead, cadmium, methylmercury and total mercury were measured in maternal and umbilical cord blood using graphite atomic absorption spectrometry. Two essential metals, copper and zinc, were also determined using ion chromatography. Lead, copper and zinc were found to be lower in the cord blood whereas methylmercury and total mercury were higher in cord blood than in maternal blood. Little differences were noted for cadmium in maternal and cord blood. Significant positive correlations were observed between the concentrations in maternal and cord blood with regard to lead (correlation coefficient, r = 0.44), copper (r = 0.34), zinc (r = 0.29), methylmercury (r = 0.44) and total mercury (r = 0.58). These results suggest that, like essential metals, most heavy metals can move rather freely across the human placenta. The potential health effects of heavy metal transfer from mothers to young infants cannot be discounted.

Relationships have been established between the concentrations of mercury in human scalp hair and environmental or dietary mercury exposures. For chronic exposures, the hair/blood ratio for mercury is in the range 200:1-300:1, and scalp hair mercury concentrations of greater than 5 ppm are indicative of mercury intoxication. These observations, coupled with the ease by which samples may be collected, transported and stored, support the use of hair analysis for evaluating mercury intoxication of the human body.
