The quality of water and sediment in the Batllava Lake were determined using the inductively coupled plasma–atomic emission spectroscopy (ICP–AES), fractionation method, and pollution indicators. The quality of the water has complied with the Council Directive (98/83 EC) and Kosovo Administrative Instruction (AI No.16/2012), except for Al and Fe. The total metals in the sediment Ba, Ni, and V exceeded the limits according to Dutch Target and Intervention Values, 2000 (the New Dutch List). Most of the analyzed metals were strongly associated with crystalline sedimentary components and were found at high levels in the residual fraction. The pollution load index (PLI), enrichment factor (EF), index of geoaccumulation (I_geo), and ecological risk index (ERI) were used for assessment of sediment contamination. The PLI values indicate a progressive deterioration. The contamination factor values indicate moderate to a considerable degree. The EF values for Ni, Cr, Cu, Zn, and V were at moderate levels, while those of As and Pb at significant levels. The ERI values for all analyzed elements were at low-risk levels. The significant percent of the Pb content was found in the organic fraction and Fe-Mn oxides, Zn in the fraction of Fe-Mn oxides, Mn in the exchangeable and carbonate fractions, and Cu in the organic fraction. The metals related to sediments in non-residual fractions should be carefully treated with a strategic management plan, and with frequent monitoring.

使用分馏方法和污染指标评估科索沃Batllava湖的水质和沉积物污染

利用感应耦合等离子体-原子发射光谱法（ICP-AES），分馏方法和污染指标确定了Batllava湖中水和沉积物的质量。除铝和铁外，水质均符合理事会指令（98/83 EC）和科索沃行政指令（AI No.16 / 2012）。根据荷兰目标和干预值，2000年（新荷兰清单），沉积物中Ba，Ni和V中的金属总量超过了限值。大部分被分析的金属与晶体沉积成分密切相关，并且在残留物中的含量很高。污染负荷指数（PLI），富集因子（EF），_地质累积指数（I _geo）和生态风险指数（ERI）用于评估沉积物污染。PLI值表明逐渐恶化。污染因子值表明中等程度。Ni，Cr，Cu，Zn和V的EF值处于中等水平，而As和Pb的EF值处于显着水平。所有分析元素的ERI值均处于低风险水平。在有机部分和Fe-Mn氧化物中发现了大量的Pb含量，在Fe-Mn氧化物部分中发现了Zn，在可交换和碳酸盐部分中发现了Mn，在有机部分中发现了Cu。与非残留馏分中的沉积物有关的金属应通过战略管理计划进行仔细处理，并进行频繁监测。
