Studies of cetaceans stranded in UK waters show high levels of toxins 20 years since global ban of most PCBs, say scientists
Nearly half of the whales and dolphins found in UK waters over the past five years contained harmful concentrations of toxic chemicals banned decades ago, an investigation has found.
Among orcas stranded in the UK, levels of PCBs, a group of highly dangerous and persistent chemicals that do not degrade easily, were 30 times the concentration at which the animals would begin to suffer health impacts, researchers said.
