| Popis: | This report explores and interprets statistical associations of Pleuronectes americanus egg contaminants with reproductive success. Winter flounder, a candidate for aquaculture, is at historically low abundance levels and has high prevalences of liver tumors. Pesticide and PCB concentrations of flounder eggs generally exceed those of more commonly analyzed marine samples, some being higher, others lower than egg concentrations linked to diminished reproduction of other resource species. Associations of individual contaminants of all chemical groups were mostly consistent with their uptake, metabolism, cumulation, toxicity, and egg concentration. Pesticides (20% of the mean total organic contaminant load of 3.2 μg/g dry weight) most strongly and significantly associated with increased mortality and defect of flounder embryos, followed by PAHs (10% of the organic contaminant load) and then metals. Total PCBs (70% of the egg organic contaminant load) had the weakest association with increased embryo... |
