Data_Sheet_1_Bioaccumulation of PCBs, OCPs and PBDEs in Marine Mammals From West Antarctica.docx
To understand the bioaccumulation and food web dynamics of persistent organic pollutants (POPs) as a function of species, age and sex in Antarctic mammals, blubber samples of 3 killer whales (Type C) and 77 pinnipeds (Weddell, Ross and crabeater seals) were collected from the Southern Ocean, Antarct...
