Trace element concentration in blubber biopsies of Humpback whales (Megaptera novaeangliae) from Madagascar: gender differences and correlation between different elements
Contaminants monitoring in wild, large cetaceans may be performed using internal organs of stranded animals. Although extremely valuable, data obtained from dead animals can be biased by poor health conditions, modifying the concentrations of pollutants. Blubber biopsies represent the most feasible...

Contaminants monitoring in wild, large cetaceans may be performed using internal organs of stranded animals.
