In 2016, an orca known as Lulu was found dead on the coast of the Isle of Tiree, the most westerly island of the Inner Hebrides in Scotland, after becoming entangled in fishing gear. A post-mortem of her body found that her body contained extremely high levels of PCBs (100 times the toxicity threshold for PCBs in marine mammal blubber) and scientists concluded that she was one of the most contaminated animals on the planet in terms of PCB burden. On examination of her ovaries, the scientists at the Scottish marine animal stranding scheme found no evidence of her ever having been reproductively active. | |
