Perfluorinated chemicals (PFCs), such as those used to make non-stick and water-repellent coatings on kitchenware and clothing, are contaminating vulnerable eel populations in lakes and rivers across Europe, according to a Greenpeace report. The report, 'Slipping Away: the presence of perfluorinated chemicals in eels from 11 European countries', reveals that European eels, once common but now in rapid decline, are widely contaminated with these man-made chemicals, a source of rising concern due to their toxicity and widespread distribution in the environment.
