CFC replacements behind hundreds of thousands of tonnes of global ‘forever chemical’ pollution
Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic ‘forever chemical’ around the globe, a new study shows.
Atmospheric scientists, led by researchers at Lancaster University, have for the first time calculated that CFC replacement chemicals and anaesthetics are behind around a third of a million tonnes (335,500 tonnes) of a persistent forever chemical called trifluoroacetic acid (TFA) being deposited from the atmosphere across the Earth’s surface between the years 2000 and 2022.
And the rate ...
