| 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 |
| reproductive health indicators of fishes from pennsylvania watersheds: association with chemicals of emerging concern. | fishes were collected at 16 sites within the three major river drainages (delaware, susquehanna, and ohio) of pennsylvania. three species were evaluated for biomarkers of estrogenic/antiandrogenic exposure, including plasma vitellogenin and testicular oocytes in male fishes. smallmouth bass micropterus dolomieu, white sucker catostomus commersonii, and redhorse sucker moxostoma species were collected in the summer, a period of low flow and low reproductive activity. smallmouth bass were the only ... | 2014 | 24934131 |
| an integrated assessment of sediment remediation in a midwestern u.s. stream using sediment chemistry, water quality, bioassessment, and fish biomarkers. | a comprehensive biological, sediment, and water quality study of the lower little scioto river near marion, ohio, usa, was undertaken to evaluate the changes or improvements in biotic measurements following the removal of creosote-contaminated sediment. the study area covered 7.5 river miles (rms), including a remediated section between rms 6.0 and 6.8. fish and macroinvertebrate assemblages, fish biomarkers (i.e., polycyclic aromatic hydrocarbon [pah] metabolite levels in white sucker [castosto ... | 2013 | 23233343 |
