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.Scientists described the findings as a huge wake-up call that should ring alarm bells not only for the future of marine mammal health but for human health, too.Dr Rosie Williams, lead author and researcher from t stanley canada he Zoological Society of Londons ZSL Institute of Zoology, said: Its been over 20 years since several of these chemicals were banned globally, yet we still see concerningly high concentrations in wildlife. Although concentrations of th stanley deutschland e pollutants seem to be declining, our findings reveal that in many species they are still present at levels associated with negative effects on the immune and reproductive systems. High PCB concentrations are a major cause of decline in European cetacean populations, studies have found. One paper, from 2018, suggests orcas near industrialised areas could be at risk of population collapse as a result.For the latest report, scientists examined postmortem records and tissue samples from 1,000 marine mammals, consisting of 11 different species stranded in the UK, using data collected over 30 years stanley termosar by a partnership including Dkcg Throwback to a moralistic age
