There are many sources of contamination to which milk could be exposed: grazing animals can ingest contaminants present in nature, such as lead in soil, or that have been deposited on grass, resulting from industrial emissions. Another possible route of contamination is represented by feed for animals, which may contain heavy and essential metals. The potential of high-resolution inductively coupled plasma spectrometry was evaluated to quantify reliably various toxic and essential elements (Fe, Zn, Pb, Cr, Ni, Cu, As, Se, Cd) in 47 samples of goat and ovine milk from various farms in Calabria (southern Italy). The results showed that concentrations of cadmium were below the limit of detection. Lead levels were below the maximum limits as set by the EC in almost all samples tested. The highest values were those of Zn followed by Fe, Cu and Se.
放牧的动物会摄入自然界中存在的污染物，如土壤中的铅，或工业排放物沉积在草上的污染物。另一种可能的污染途径是动物饲料，其可能含有重金属和必需金属。评估了高分辨率电感耦合等离子体质谱法可靠定量来自意大利南部卡拉布里亚不同农场的47份山羊奶和绵羊奶样品中各种有毒和必需元素（铁、锌、铅、铬、镍、铜、砷、硒、镉）的潜力。结果表明，镉浓度低于检测限。几乎所有测试样品中的铅含量均低于欧盟规定的最高限量。含量最高的是锌，其次是铁、铜和硒。
