Assessing the Dietary Exposure of Harbour Seals (Phoca vitulina) to Persistent Organic Pollutants (POPs) in the Strait of Georgia (British Columbia, Canada) and Puget Sound (Washington State, USA)

Elevated Persistent Organic Pollutants (POPs) concentrations have been detected in high trophic level wildlife and have been associated with endocrine disruption and other adverse health effects. Recent evidence indicates that harbour seals (Phoca vitulina) inhabiting Puget Sound, WA are approximately seven times more contaminated with polychlorinated biphenyls (PCBs) than those inhabiting the ...

Long-term Effects of Bioaccumulation in Ecosystems

Extensive damage to organisms and declines in wildlife populations have been observed together with long-term bioaccumulation and biomagnification of persistent xenobiotic chemicals. Heavy metals, especially organic or biomethylated mercury, lead, cadmium and organic tin compounds have caused environmental damage through bioaccumulation on a local scale. Effects on wildife caused by bioaccumula...

Organochlorine pollution in tropical rivers (Guadeloupe): role of ecological factors in food web bioaccumulation.

Concentrations of organochlorine pesticides and stable isotope ratios of nitrogen and carbon were measured in a tropical freshwater ecosystem to evaluate the contamination level of biota and examine the bioaccumulation patterns of pollutants through the food web. Chemical analyses showed a general and heavy contamination of the entire food web. They revealed the strong accumulation of pollutant...
