The study aims at investigating whether, and if so, to what extent the strong presence of urban and industrial waste in a territory may cause PCB contamination in goat milk produced therein.
We compared PCB concentrations in goat milk from three different locations in the Campania region (Italy). One of the three locations, together with its surrounding area, has long suffered from illegal waste disposal and burning mainly by the so-called Ecomafia. The other locations, not involved in these illegal activities, allowed us to create a control group of goats with characteristics very similar to those of main interest.
In milk from the waste contaminated area we identified high PCB concentrations (six indicator PCBs amounted to 170 ng g on lipid weight, on average), whereas there was an almost total absence of such pollutants in milk from the control group. Concentrations of the six indicator PCBs were above the current European maximum residue limit fixed by the EU. At the same time, we found a lower average value of lipid content and a negative relationship between lipid content and PCB concentrations.
Evidence indicates the potential health risk for consumers living in areas involved in illegal dumping of waste.
本研究旨在调查某一地区城市和工业废物的大量存在是否会导致该地区生产的山羊奶受到多氯联苯污染，若会，污染程度如何。
我们比较了意大利坎帕尼亚地区三个不同地点的山羊奶中多氯联苯的浓度。三个地点中的一个及其周边地区长期遭受非法废物处理和焚烧的困扰，主要是所谓的“生态黑手党”所为。另外两个地点未涉及这些非法活动，这使我们能够创建一个特征与主要研究对象非常相似的山羊对照组。
在受废物污染地区的牛奶中，我们检测到了高浓度的多氯联苯（六种指示性多氯联苯的平均脂重含量达170纳克/克），而对照组牛奶中几乎完全没有此类污染物。六种指示性多氯联苯的浓度超过了欧盟规定的现行欧洲最大残留限量。同时，我们发现脂肪含量平均值较低，且脂肪含量与多氯联苯浓度之间呈负相关。
有证据表明，生活在涉及非法倾倒废物地区的消费者存在潜在健康风险。
