Experiments were conducted to evaluate the effect of dietary benzo[a]pyrene (B[a]P) on the growth and hematological parameters of rockfish, Sebastes schlegeli, after they were fed with subchronic dietary B[a]P for 30 days. The weight growth rate of the rockfish was significantly different from that of the control group at dietary B[a]P concentration of 1.5 and 2.0 mg/kg. Significant reduction in red blood cells, hematocrit, and hemoglobin were observed during 30 days of exposure to the highest concentration. Over 30 days, serum AST increased at a B[a]P concentration of 1.5 mg/kg and LDH increased at a B[a]P concentration of 1.0 mg/kg concentration. However, no changes were observed in ALT, total protein, magnesium or calcium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
