Mapping the Coal Ash Contamination
The release of bioaccumulative toxins from coal ash, including arsenic, cadmium, chromium, lead, mercury, and selenium, has caused fish kills, deformities in fish and amphibians, and health hazards to people consuming contaminated fish. Selenium is a particularly dangerous contaminant because it is toxic to aquatic life at very low levels.
Trace Elements
Nutrients. 2015;7 (5):3252-3263. Many of the trace elements to which people are regularly exposed are necessary for health, but some have no biologic function. Of the mineral elements discussed here, those that have nutritional significance are chromium, cobalt, copper, iodine, iron, manganese, nickel, selenium, and zinc.

cadmium, arsenic chromium, thallium and lead. As trace elements, some heavy metals (e.g. copper, iron, zinc, manganese and selenium) are essential to maintain the metabolism of the human body. However, at higher concentrations they can lead to poisoning [1]. Heavy metals can enter the human food through water, air, soil, plants and animals.

Thallium selenite (TlSe) has a MW of 283.34 and thallium (Tl) has a MW of 204.38. To derive the oral RfD of 1E-05 mg/kg-day for thallium selenite, the thallium RfD of 1E-05 mg/kg-day is multiplied by the MW of thallium selenite (283.34) divided by the MW of thallium (204.38). 5.22 Polycyclic Aromatic Hydrocarbons (PAHs)

Solids, gases, and liquids are identified; all other species are aqueous. Reduction reactions in acidic solution are written using H + in place of H 3 O +. You may rewrite a reaction by replacing H + with H 3 O + and adding to the opposite side of the reaction one molecule of H 2 O per H +; thus. H 3AsO 4 + 2H + + 2e – − ⇀ ↽ − HAsO 2 ...
