The concentrations of thirteen metals (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn) were analyzed in waters and sediments of the Badovci Lake. The total metal concentrations in the water followed the descending order: Fe > Al > Mn > Cu > Ba > Zn > As > Ni > Pb > V > Co > Cd > Cr, and the total metal content in the sediments also followed the descending order: Fe > Al > Mn > Ni > Cr > Pb > Ba > Zn > V > Cu > As > Co > Cd. According to EC 98/83, Al, Fe, and Mn at some sampling sites exceeded safety limits for drinking water, whereas other elements were at acceptable levels. The total content of Cr, Cu, Ni, Pb, and V in the sediments exceeded the target values of the New Dutch List. Using pollution indicators such as the contamination factor (CF) and geoaccumulation index (I), most of the samples were unpolluted to moderately polluted by Cu, Cr, Pb, V, and Ni. The values of the pollution load index (PLI) were more than one (>1), indicating progressive deterioration of the sediment quality. The enrichment factor (EF) for all the studied metals suggests their enrichments in sediments of the Badovci Lake. Most of the elements were found in the residual fraction strongly bonded to the crystalline component. Pb, Mn, and Cu were bound in the organic and exchangeable components. The extent of pollution by heavy metals in sediments of the Badovci Lake implies that the environmental condition is relatively stable, and attention should be paid to metals bonded in the extractable and organic phases. It is recommended to periodically monitor water and sediment quality.
对巴多维奇湖水体和沉积物中的13种金属（铝、砷、钡、镉、钴、铬、铜、铁、锰、镍、铅、钒和锌）浓度进行了分析。水中金属总浓度排序为：铁＞铝＞锰＞铜＞钡＞锌＞砷＞镍＞铅＞钒＞钴＞镉＞铬，沉积物中金属总含量排序为：铁＞铝＞锰＞镍＞铬＞铅＞钡＞锌＞钒＞铜＞砷＞钴＞镉。根据欧盟理事会指令98/83，部分采样点的铝、铁和锰超过了饮用水安全限值，而其他元素处于可接受水平。沉积物中铬、铜、镍、铅和钒的总含量超过了荷兰新列表的目标值。使用污染因子（CF）和地累积指数（I）等污染指标，大多数样品受到铜、铬、铅、钒和镍的污染程度为未污染至中度污染。污染负荷指数（PLI）值大于1，表明沉积物质量在逐渐恶化。所有研究金属的富集因子（EF）表明它们在巴多维奇湖沉积物中存在富集。大多数元素存在于与结晶成分强烈结合的残留部分中。铅、锰和铜则结合在有机和可交换部分中。巴多维奇湖沉积物中重金属的污染程度意味着环境状况相对稳定，应关注结合在可提取和有机相中的金属。建议定期监测水体和沉积物质量。
