Halogenated flame retardants in stranded sperm whales (Physeter macrocephalus) from the Mediterranean Sea
In recent years, decline of marine mammals' populations and increased frequency of strandings have arised the interest on the role that pollution may have in these events. The present work aimed at quantifying levels of brominated flame retardants (BFRs) and dechloranes (DECs) in tissues of 3 a...
