Today a Greenpeace study shows how toxic man-made chemicals are contaminating the European eel population [1]. The study of European eels (Anguilla anguilla) from 20 rivers and lakes in 10 EU countries [2] found that eels from every location contained residues of at least one brominated flame retardant (BFR) compound, indicating the widespread dispersal of these chemicals in European waters. Levels of BFRs found in a sample of UK eels from the River Thames were more than double those recorded in the majority of other samples in this study.
