| reference values for exposure to pah contaminants: comparison of fish from ohio and mid-atlantic streams. | reference values for background exposures of benzo[a]pyrene (bap)- and naphthalene (naph)-type metabolites were calculated for white sucker, northern hog sucker, and rock bass from the mid-atlantic region based on the 90th percentile of a probability-based sample. preliminary findings are presented for common carp. bile was collected from fish and assayed for polycyclic aromatic hydrocarbon metabolites using the fluorescent method of lin et al. exposure reference values for white sucker were 0.3 ... | 2006 | 16314983 |
