Analytical results are reported for the determination of heavy metals in environmental matrices, sampled in an ecosystem inside a protected area: the Park of the Po Delta, located near the thermoelectric power station ENEL of Porto Tolle, one of the greater in Italy. The elements determined, in sediments and superficial water, are Ni and V, linked to the fuel oil combustion. However, in order to obtain a complete picture enough of heavy metals polluting load in the study areas, the following elements: Cd, Co, Cr, Cu, Fe, Mn, Pb and Zn are also determined. For all the elements, in addition to the detection limits, precision and accuracy are also given: the former, expressed as relative standard deviation (s(r)), and the latter, expressed as relative error (e), were good, being in all cases lower than 6%.
报告了在一个保护区内的生态系统（位于意大利较大的热电厂之一托雷港埃尼电力公司附近的波河三角洲公园）中采集的环境基质中重金属测定的分析结果。在沉积物和表层水中测定的元素是与燃油燃烧有关的镍和钒。然而，为了充分了解研究区域中重金属污染负荷的全貌，还测定了以下元素：镉、钴、铬、铜、铁、锰、铅和锌。对于所有元素，除了检测限外，还给出了精密度和准确度：前者以相对标准偏差（s(r)）表示，后者以相对误差（e）表示，结果良好，在所有情况下均低于6%。
