Fish tissue arsenic
Webmethylmercury in fish tissue data under the reasonable potential to exceed criteria (RPTE) process (Idaho Department of Environmental Quality, 2005). The RPTE process is designed to protect human health with a fish-tissue methylmercury value not to exceed 80 percent of the 0.3 mg/kg criterion in the receiving water body. Webthe toxic arsenic species of most concern in fish and shellfish include inorganic arsenic, monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA), all of which are minor constituents. Quantitative data on inorganic arsenic in freshwater fish is sparse, and the toxicity to humans of fish tissue containing arsenic has not been well studied.
