Bottlenose dolphins in the English Channel harbor a 'toxic cocktail' of chemicals

Bottlenose dolphins in the English Channel harbor a "toxic cocktail" of chemicals, some of which have been banned for decades and which may be harming the rare marine mammals' health, scientists said Thursday. Belgian and French scientists said they've detected high accumulations of industrial fluids and mercury in the blubber and skin of dolphins in the Normanno-Breton Gulf, off the northwest coast of France.
