Figure 8A
Probability of streams having whole-fish samples that exceed (A) 5 µg/kg (which is the reporting level for dieldrin in whole fish and also corresponds to an EPA screening value at a cancer risk of 1:50,000) and (B) 25 µg/kg (which corresponds to the EPA screening value at a cancer risk of 1:10,000)
In both maps, whole-fish samples are assumed to have 4.2 percent lipid content (the mean value for largemouth bass sampled by the NCBP and NAWQA programs combined). The EPA screening values apply to edible fish tissue. mi, mile; µg/kg, microgram per kilogram.
