“…Atmospheric exposures occur from outgassing from rock or through volcanic activity. Human sources of atmospheric mercury include coal burning [9] and mining (mercury and gold in particular). Atmospheric elemental mercury settles in water, where it is converted by microorganisms into organic (methyl or ethyl) mercury, which is ingested by smaller creatures which are eventually consumed by larger fish.…”

Mercury is a toxic heavy metal which is widely dispersed in nature. Most human exposure results from fish consumption or dental amalgam. Mercury occurs in several chemical forms, with complex pharmacokinetics. Mercury is capable of inducing a wide range of clinical presentations. Diagnosis of mercury toxicity can be challenging but can be obtained with reasonable reliability. Effective therapies for clinical toxicity have been described.

“…Using this methodology, a direct mercury analysis can be completed for a dietary supplement sample in approximately six minutes. This direct analysis approach recently proved to be successful for completing mercury measurements in the coal, fly ash, bottom ash, and flue gas desulfurization material from coal-fired power plants [31] and in solid peat samples [32]. A similar methodology utilizing a pyrolysis unit coupled with atomic absorption spectrometry determined the concentration of mercury in three Chinese medicinal herbs [33].…”

The concentrations of mercury in forty, commercially available dietary supplements, were determined using a new, inexpensive analysis technique. The method involves thermal decomposition, amalgamation, and detection of mercury by atomic absorption spectrometry with an analysis time of approximately six minutes per sample. The primary cost savings from this approach is that labor-intensive sample digestion is not required prior to analysis, further automating the analytical procedure. As a result, manufacturers and regulatory agencies concerned with monitoring lot-to-lot product quality may find this approach an attractive alternative to the more classical acid-decomposition, cold vapor atomic absorption methodology. Dietary supplement samples analyzed included astragalus, calcium, chromium picolinate, echinacea, ephedra, fish oil, ginger, ginkgo biloba, ginseng, goldenseal, guggul, senna, St John's wort, and yohimbe products. Quality control samples analyzed with the dietary supplements indicated a high level of method accuracy and precision. Ten replicate preparations of a standard reference material (NIST 1573a, tomato leaves) were analyzed, and the average mercury recovery was 109% (2.0% RSD). The method quantitation limit was 0.3 ng, which corresponded to 1.5 ng/g sample. The highest found mercury concentration (123 ng/g) was measured in a concentrated salmon oil sample. When taken as directed by an adult, this product would result in an approximate mercury ingestion of 7 µg per week.

“…Extrapolation of the effects of the short-term, high-dose cases like Iraq to a maximum safe dosage level for long term exposure in humans is unreliable. Additional case studies in the Seychelle and Faroe Islands are being conducted to further quantify methylmercury exposure risk assessment (Whipple et al, 1996;Brown, 1999;Environmental Protection Agency, 2003;Lipfert et al, 2005). However it is of concern that these data are yet insufficient for a complete quantification of low-level mercury exposure (Davis, 1997;Lipfert et al, 2005).…”

“…The EPA is seeking additional information regarding this (Senior et al, 1998). On a mass basis nearly thirty percent of the coal used in the U.S. is subbituminous, the remainder being bituminous (Brown et al, 1999). The relative amount of mercury and chlorine in raw coal has a profound effect on the mercury speciation in the flue gas of a coal-combustion facility.…”
