Method Development for Quantification of Different Persistent Organic Pollutants in Ringed Seal (Phoca hispida) from the Baltic Sea
Persistent organic pollutants such as polychlorinated biphenyls (PCBs), DDT and polybrominated diphenyl ethers (PBDEs) tend to accumulate in biota and are transferred through the aquatic food web, which result in a high accumulation in marine mammals. In recent years various novel flame retardants (...
