Eve Irvine is pleased to welcome Hélène Duguy, Senior Environmental Lawyer at ClientEarth. PFAS pollution is widespread, these highly persistent chemicals have been detected in water and soil, food and consumer products, and even the human body. The risks are increasingly well documented, alternatives now exist for many uses, and there is an extensive regulatory framework that is in place. Duguy argues that the central problem is therefore not simply a lack of scientific knowledge or legislation, but rather weak enforcement, slow regulation and corporate resistance. And so hazardous chemicals remain in circulation even when restrictions exist.
