The history of metal pollution in the semi-enclosed and human-influenced marine system of the Boka Kotorska Bay (Southern Adriatic) was studied considering geological composition of the surrounding catchment, the sedimentation rate and the mineralogical and early diagenetic processes in the recent sediments. The determination of background concentrations of metals, undertaken for the first time in this environment, proved to be particularly important for Ni and Cr, which are naturally enriched in the sediments of the southern Adriatic. The results showed widespread moderate contamination with Pb and Sn since the 1970s, while the upper layers of sediments near shipyards, marinas and urban areas were more contaminated with Sn, Cu, Pb, Zn, Cd, As, Sb and Mo. The transport of material through the narrow straits separating different parts of Boka Kotorska Bay resulted in a different geochemical composition of the smaller bays and a limited distribution of contaminated sediments from local sources.
通过考虑博卡科托尔斯卡湾（亚得里亚海南部）半封闭且受人类影响的海洋系统周边集水区的地质组成、沉积速率以及近期沉积物中的矿物学和早期成岩过程，对该海湾的金属污染历史进行了研究。在这种环境中首次对金属背景浓度进行测定，结果表明这对于镍和铬尤为重要，因为亚得里亚海南部的沉积物中天然富含这两种元素。结果显示，自20世纪70年代以来，铅和锡存在广泛的中度污染，而造船厂、码头和城市地区附近沉积物的上层受到锡、铜、铅、锌、镉、砷、锑和钼的污染更为严重。物质通过分隔博卡科托尔斯卡湾不同区域的狭窄海峡进行传输，导致较小海湾的地球化学组成不同，且来自当地源的污染沉积物分布有限。
