Validation of bioassays for assessing the contamination of marine environments
57-65 Various biomarkers were used to determine the exposure of fish (Arius felis and Micropogon undulatus) from Galveston Bay (GB), Texas, USA to organic contaminants. Sediment levels of polynuclear aromatic hydrocarbons (PAHs) in GB ranged from 81 to >1000 ng/g and polychlorinated biphenyls (PC...
