Mercury effects

Alternatively, there are also iuhibitors that decrease the rate of hydrogen generation and thus decrease corrosion. Mercury, effective at inhibiting 2iac corrosion, has long been used as an additive to 2iac anodes. More recentiy, however, because of iacreased iaterest ia environmental issues, the amount of mercury ia alkaline cells has been reduced. 

Subcategories of bioindicators at suboiganismal levels are generally referred to as biomarkers. Biomarkers may reflect either exposure, effect, or susceptibility of these, biomarkers of effect are both more valuable and more difficult to find. An ideal biomarker of mercury effect would be ...

Accordingly, ATSDR used maternal hair mercury levels as the exposure measurement to derive a chronic MRL for methylmercury. While hair analysis can be confounded by outside sources of contamination (e g., as might occur in certain occupational settings) (Hac and Krechniak 1993), the study population used as the basis of the chronic oral MRL for methylmercury is far removed from external or industrial sources of mercury, effectively eliminating this as a consideration for the following analysis.

The significance of mercury concentrations in amphibian tissues is not Imown with certainty and requires additional research for satisfactory risk assessment. The following areas are recommended for study acclimatization and adaptation to mercury mercury remobilization during periods of metamorphosis, hibernation, estivation, and reproduction critical organ concentrations and biomarkers of adverse mercury effects. These studies should also consider the influence of exposure duration and dose, mercury speciation, and mercury interaction with other metals. 

In 2008, Congress amended TSCA 12(b) by passing the Mercury Export Ban of 2008, which prohibits the export of elemental mercury effective...
