- Accumulation of contaminant residues in marine animals
Nature
Environmental pollution is characterized by the accumulation of toxic metals, chemical and petrochemical residues and radionuclides in marine wildlife. Radionuclides are accumulated as a result of fallout from nuclear weapons testing and from nuclear reactor accidents.
Incidence
The level of PCBs, polychlorinated biphenyls, in marine mammals' fat is rising worldwide.
Counter-claim
The so-called "accumulation of pollutants in marine wildlife" is vastly overstated and not an important problem at all. Marine ecosystems have always adapted to changes, and the levels of pollutants are often exaggerated by alarmists. There is little concrete evidence that these pollutants cause significant harm to marine species or disrupt food chains. Instead of panicking, we should focus on real, pressing issues rather than hypothetical threats to ocean life.
