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 pgg(-1) fat basis, respectively. The mean dl-PCB concentration was 2.01 ngg(-1) fat basis, while cumulative ndl-PCB levels ranged from 1.02 to 20.42, with a mean of 4.92 ngg(-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.
在意大利撒丁岛工业化地区的 80 个绵羊奶样本中，测量了 7 种多氯二苯并对二恶英（PCDDs）、10 种多氯二苯并呋喃（PCDFs）和 22 种多氯联苯（PCBs）的浓度，包括 12 种非和单-邻位多氯联苯（dl-PCBs）。PCDDs 和 PCDFs 的平均浓度分别为 2.45 和 3.69 pg/g 脂肪。dl-PCB 的平均浓度为 2.01 ng/g 脂肪，而累积非 dl-PCB 水平范围为 1.02 至 20.42，平均值为 4.92 ng/g 脂肪。以 WHO-TEQ/g 脂肪表示的结果表明，牛奶的污染水平低于 EC 法规规定的人类消费限量值。同样，所有调查的牛奶的 PCDD/Fs 浓度均低于欧盟行动水平，而 dl-PCBs 浓度超过了 2.0 pg WHO-TEQ/g 脂肪的行动水平。这些发现表明，需要继续开展一般性监测计划，包括来自远离污染物排放工业地区的牛奶样本，以便更好地评估工业活动对周围环境的影响。
