Heavy Metals, Organochlorines and Polycyclic Aromatic Hydrocarbons in Sperm Whales Stranded in the Southern North Sea During the 1994/1995 Winter
Context of the study
In the winter of 1994-1995 21 sperm whales beached along the North Sea shorelines. The reason for the mass strandings was that these sperm whales became trapped as a group in the unfavorable North sea. However, these animals can be used to obtain valuable information on accumulation and excretion mechanics of stable pollutants and the overall health status of these long-living marine mammals.
Content of the study
7 of the 21 sperm whales beached on Belgian and Dutch territory. One of them died at least a day before beaching, the six others died shortly after stranding. The muscles, livers kidneys and fat of these 7 whales were examined for the presence of heavy metals, organochlorines and PAH's.
Main results
High concentrations of cadmium, mercury and PCB were retrieved in these sperm whales.
