A killer whale found dead on a Scottish island had one of the highest ever levels of toxic chemicals found in its body.
A postmortem for the whale, known as Lulu, found her blubber contained 100 times more polychlorinated biphenyls pollutants (PCBs) than what would usually give marine animals health problems.
Lulu was discovered on the Scottish island of Tiree having become tangled in fishing ropes last year.
But scientists have now claimed the dangerous toxins could have played a role in her death by weakening the killer whale.
Dr Andrew Brownlow, head of the Scottish Marine Animal Stranding Scheme told the BBC that Lulu had "shocking levels of PCBs".
Manmade chemicals found to contain PCBs have been widely used in plastics to paints and electrical equipment over the past century and can be found in landfill sites.
