“I think we could see more fish deaths happen because of this.” “I have a feeling that you’re going to be seeing much more of these short sharp rainfall events after dry periods of weather,” he says. “And then there was this flash flood, which led to sewage systems being overwhelmed by rainwater, leading to the release of raw sewage into this river.”īoxall suspects that climate change will lead to more mass deaths of fish around the country.
“The weather in the UK in recent weeks has been very dry and this led to a massive reduction in the of the river Foss,” says Boxall. Paracetamol isn’t likely to kill fish, he says, but raw sewage can dramatically deoxygenate a river and lead to high fish mortalities. Paracetamol concentration in rivers is a good indicator of raw sewage being dumped into the water, as sewage treatment works are usually quite effective at removing the drug, says Boxall.
