Research of killer whales in the southern Atlantic ocean and Mediterranean have shown that their blubber contains high levels of pollutants called PCBs, whilst killer whales found along the Norwegian coast have been assumed to be healthy and at low risk from pollution. This is because when researchers took samples from nine Norwegian killer whales in 2002, they found lower levels of pollutants than other populations.
