Abstract
"Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like. polychlorinated biphenyls (DL-PCBs) are widespread contaminants with important implications for. environmental and human health. Milk and dairy products consumption has been classified. as one of the primary pathways of human exposure to these toxic chemicals. In this study. we evaluated the levels of 17 laterally substituted PCDD\/Fs and 12 DL-PCBs in 45 sheep milk. samples collected from 15 farms in Sardinia (Italy). Mean concentrations of PCDDs and PCDFs. were 2.31 and 3.11 pg.g. -1. fat basis, respectively. Among DL-PCBs, only PCB 118 was detected. in 51.1% of samples. Contamination of milk by PCDD\/Fs and DL-PCBs (0.92 pg WHO-TEQ g. . fat) being within the permissible limit set by the European Commission (6 pg WHO-TEQ g. fat). gives no indication of particular health risk. However, continuous surveillance in milk is needed. to correctly evaluate both the environmental impact and the human health risk."I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
