Serum levels of PCDDs, PCDFs and PCBs in non-occupationally exposed population groups living near two incineration plants in Tuscany, Italy

摘要: Abstract A pilot study was carried out in Tuscany, Italy, to provide preliminary information on the concentrations of polychlorinated dibenzodioxins (PCDDs), dibenzofurans (PCDFs), dioxin-like polychlorobiphenyls (DL-PCBs), and selected non-dioxin-like PCBs (NDL-PCBs) groups subjects living vicinity two incineration plants. Seventy-four volunteers were enrolled from areas identified as under a potential impact incinerator emissions not exposed areas. No significant differences observed between types Total PCDDs, PCDFs, DL-PCBs resulted be range 23–30 pg WHO–TEQ g −1 , lipid base, for 27–54 year age groups, while increased 40–44 pgTEQ g 55–67 year groups. The levels PCDDs PCDFs good agreement with those unexposed population contribution total TEQ appreciably higher than currently general Italy other countries. As NDL-PCBs, serum six “indicator” congeners 240–300 ng g raise NDL-PCB body burden (430–470 ng g base) 55+ year expected age-dependent increase. findings this do show an incremental exposure samples around plants, whereas PCB congener profiles all suggest possible area interest industrial activities near settlements.
