Brominated dioxins (PBDD/Fs) and PBDEs in Marine Shellfish in the UK
International audience The occurrence of brominated dioxins (PBDD/Fs) and polybrominated diphenyl ethers (PBDEs) was investigated in commonly consumed species of marine shellfish in the UK. Individual samples of Pacific oysters (Crassostrea gigas), native oysters (Ostrea edulis), mussels (Mytilus ed...
