The cause of concern caused death killer whales washed ashore

The whale named Lulu is dead and washed ashore. More important than the cause may cause many scientists startled and worried.

A killer whale named Lulu (named after last year's landing on Tiree (Scotland)) died of an "ominous" cause for scientists.

The Scottland (SMASS) Marine Animal Research Program, along with Aberdeen University, studied the whale's body and found something less positive.

Dr. Andrew Brownlow, Director of SMASS expressed his astonishment after examining and analyzing Lulu's corpse, he discovered that the whale died of infection with a high concentration of polyclorinated biphenyl (PCB) and high concentration. most ever recorded.

PCB is a persistent organic pollutant , it is regulated in the Stockholm Convention since the 1970s and has been banned in many countries around the world.

Dr. Andrew thinks that Lulu has a high level of poisoning 80 times the safe level that this fish can tolerate. He also said that just 20-40mg / kg stored in tissues can cause serious physiological harms such as weakening the immune system, high infertility.

But in Lulu whale carcass, this number is up to 957mg / kg! A number that is so terrible that Lulu could say is the most poisoned individual on the planet.

Director Simon Walmsley of the International Fund for Nature Protection (WWF) also warned: "In this case, PCBs will stay in the environment and may continue to poison many other animals for decades". .

Environmental experts are also concerned that, not only Lulu, many other individuals in her herd (including 8) can be poisoned as well.

Veterinary pathologist Andrew Brownlow said many studies show that killer whale populations may suffer severe PCB poisoning when they accumulate toxins from their prey. On the other hand, dolphins kill at the top of the food chain so they can be the most poisoned.

This is the last killer whale in the waters around England, so ocean pollution can make this fish disappear from here in the near future.
