Accumulation of persistent organic pollutants in Tasmanian platypus (Ornithorhynchus anatinus)

Tailfat samples were collected from 56 platypuses, 38 male and 18 female in Tasmania. No statistically significant, nor apparent, differences between the sexes were found for tailfat lipid levels and DDT and its metabolites, Lindane and PCB concentrations in tailfat lipid. Apparently—but not statistically—significantly different levels of DDT and its metabolites, Lindane and PCB concentrations were found in animals from different geographic regions of the State. Higher concentrations of DDT and its metabolites and Lindane were related to the intensity of agricultural activity and elevated PCB levels were mainly found in animals from zones with industrial and hydroelectric developments.
