"The objectives of this report are: 1) to determine a range of conservative concentrations of inorganic arsenic in seafood (including fish, invertebrates and algae) for use in Region 10 human health exposure assessments and related activities; 2) to identify speciation methods which may be used by the EPA Region 10 laboratory to study inorganic and total arsenic content in northwest fish, shellfish and edible marine plants which currently do not have documented data available; and, 3) to present facts and implications of the toxic potential of arsenic in seafood to human populations ingesting this seafood and discuss related exposure assessment approaches. How significant is dietary intake of inorganic arsenic from seafood? What is currently known about the long-term effects of organic arsenic from seafood consumption?" -- p. 1.
