Substantial decline of polychlorinated biphenyls serum levels 10Â years after public health interventions in a population living near a contaminated site in Northern Italy

PCBs serum levels declined from the 2003 to 2013 survey though they are still high in the elderly mainly because of past intake of locally produced contaminated food. Present findings suggest that PCBs food chain contamination and human absorption have been interrupted successfully in the area since discovery of the pollution in 2001.
