Sources and processes controlling the occurrence of legacy POPs and organic contaminants of emerging concern in European air
Persistent Organic Pollutants (POPs) are chemicals that have harmful impact on human health and the environment. POPs are now regulated but were previously widely used in different applications as additives in products and as pesticides. Despite emission reductions, possible unintentional emissions...
