Abstract

Introduction: Taranto Province (Puglia Region, Southern Italy) is of particular Public Health relevance due to the presence of industrial sources of dioxins and PCBs. The aim of this study was to analyze the spatio-temporal distribution of these pollutants in milk and cheese produced from 2013 to 2018.

Materials and methods: Raw milk and dairy products were sampled in the farms located within 20 km from the industrial area.

Results: 1005 milk samples were collected. Median (IQR) concentrations were: dioxins 0.21 (0.21) pg WHO-TEQ/g fat; dioxins+DL-PCBs 0.83 (0.71) pg WHO-TEQ/g fat; NDL-PCBs 1.92 (1.56) ng/g fat. Overall, only 6 (0.6%) samples were found to be non-compliant for at least one pollutants group. Temporal analysis showed a decreasing trend in dioxins and PCBs concentrations over the observed years and higher values in the first trimester. Spatial analysis showed higher levels of PCBs in areas closest to the industrial pole. 70 dairy products samples were collected. Median pollutants concentrations were far below the EU limits and no exceedances were observed.

Conclusions: The extremely low number of exceedances appeared as an encouraging result and supported the validity of the Public Health measures adopted by the Department of Prevention of Taranto.

塔兰托省(意大利南部普利亚地区)牛奶和乳制品中的二恶英和多氯联苯污染:六年时空监测研究。

导言:塔兰托省(意大利南部普利亚地区)由于存在二恶英和多氯联苯的工业来源，具有特别的公共卫生相关性。本研究的目的是分析2013年至2018年牛奶和奶酪中这些污染物的时空分布。材料和方法:在距工业区20公里范围内的农场取样原料奶和乳制品。结果:共采集牛奶样品1005份。中位(IQR)浓度为:二恶英0.21 (0.21)pg WHO-TEQ/g脂肪;二恶英+ dl -多氯联苯0.83 (0.71)pg WHO-TEQ/g脂肪;NDL-PCBs 1.92 (1.56) ng/g脂肪。总体而言，只有6个(0.6%)样本被发现至少有一个污染物组不符合要求。时间分析显示，二恶英和多氯联苯浓度在观测年份呈下降趋势，在妊娠早期呈较高水平。空间分析显示，在最靠近工业极点的地区，多氯联苯水平较高。采集了70份乳制品样品。污染物浓度中位数远低于欧盟限值，没有发现超标现象。结论:极低的超标次数是一个令人鼓舞的结果，支持了塔兰托省防治厅采取的公共卫生措施的有效性。
