Serum levels of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and polychlorinated biphenyls in a population living in the Naples area, southern Italy

The objective of this study was to estimate the levels of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (DL-PCBs and NDL-PCBs) in blood serum obtained from non-occupationally exposed volunteers living in the Naples area (Campania Region, southern Italy).The samples were taken from two geographical zones: one was an urban area of Naples and its surroundings and the other was located in an area deemed to be at high environmental risk.Total mean concentrations of these persistent pollutants proved to be in the range 1.43-17.38pgWHO-TEQ1998g-1 lipid for PCDD/Fs, and 0.98-25.45pgWHO-TEQ1998g-1 lipid for DL-PCBs. NDL-PCBs were in the range 316.57-482.90ngg-1 lipid.No significant differences were observed between women and men, nor between donors living in the two different areas.The mean levels of PCDD/Fs and PCBs in the population living in the Naples area were lower than those observed in some studies of populations living in exposed areas (near incineration plants or industrial sites) and urban or rural areas. © 2013 Elsevier Ltd.
