Abstract

Concentrations of 7 polychlorinated dibenzo-p-dioxins (PCDDs), 10 polychlorinated dibenzofurans (PCDFs) and 22 polychlorinated biphenyls (PCBs), including 12 dioxin like-PCBs (non- and mono-ortho PCBs) were measured in 80 sheep milk samples from farms located in an industrialized area of Sardinia, Italy. PCDDs and PCDFs mean concentrations were 2.45 and 3.69 pg g−1 fat basis, respectively. The mean dl-PCB concentration was 2.01 ng g−1 fat basis, while cumulative ndl-PCB levels ranged from 1.02 to 20.42, with a mean of 4.92 ng g−1 fat. The results expressed in pg WHO-TEQ/g fat showed that contamination level of milk was below the limit values for human consumption established by EC legislation. In the same way, all the investigated milk exhibited PCDD/Fs concentrations below EU action levels, while dl-PCBs concentrations exceeded the action level of 2.0 pg WHO-TEQ/g fat. These findings point to the need to continue to conduct general monitoring programmes, including also milk samples from areas not close to the contaminant-emitting industries, in order to better evaluate the impact of industrial activities on surrounding environment. ⺠PCDD/Fs and PCBs were determined in sheep milk samples. ⺠Milk samples were collected from an industrialized area of Sardinia, Italy. ⺠Overall milk contamination level was below the limit values for human consumption. ⺠Samples the nearest to pollution sources had concentrations above the action level. ⺠On the whole the results revealed a situation of moderate contamination.
