Persistent organic pollutants are subject to long-range transport and also occur in the environment far from their source. They accumulate in the suspended solids of watercourses and in the food chain. They are toxic to humans and wildlife.
One of the principles of environmental protection is that wastes must be recycled. However, it is counterproductive to reintroduce a recycled product which contains pollutants. An UBA study examines how this can be prevented for five persistent organic pollutants (POP).
For a long time the chemical hexabromocyclododecane, or HBCD, was the most economically significant flame retardant used in polystyrene foam for insulation materials. Our background paper, also available in English, provides answers to the most important questions concerning the phase-out.
Soil pollutants are ubiquitous. They stem from natural sources, factories, farming, transportation, and households. Deposits of such soil pollutants can seep into the groundwater or are uptaken by plants, they can pose an environmental and health risk.
Persistent organic pollutants (POPs) are a worldwide problem. PCB, which is a POP, has not been used in Germany for years and only occurs in certain wastes.
