Univariate and multivariate ANOVAs for equal pollutant bioaccumulation are presented. A Multivariate ANOVA was also conducted on a set of all pollutants combined (Sum 36 PCBs, HCB, pp-DDE, pp-DDT, Sum 10 PBDEs, Sum 3 HBCDs and nine metals). Concentration of PCBs, OCPs and BFRs is expressed in ng/g of wet weight. Metal concentration is expressed in μg/g of dry weight. DL = below detection limit. * = statistically significant.
