In this study, the concentrations of 13 elements (Al, Fe, Mn, Cr, Ni, Zn, Co, As, Pb, Cu, Mo, Hg, and Cd) were determined in the sediments of three different sites in the Kapulukaya Dam Lake between May 2007 and November 2008. They ranged from 1.47 to 4.64 for Al, 0.92 to 3.48 for Fe (in percent), 326.60 to 1053.00 for Mn, 98.00 to 1,116.00 for Cr, 24.70 to 127.10 for Ni, 14.80 to 124.20 for Zn, 11.0 to 43.20 for Co, 5.00 to 29.30 for Cu, 9.10 to 69.70 for As, 8.60 to 34.00 for Pb, 2.50 to 5.20 for Mo, 1.00 to 1.60 for Hg, and 0.50 to1.80 for Cd in microgram per gram dry weight sediment. The contamination degree of the sediment was assessed on the basis of enrichment factor and corresponding sediment quality guideline. The calculated enrichment factors (EF, measured metal vs. background concentrations) indicated that the effect of man-made activities on the occurrence of concentrations could be accounted for the majority of heavy metals namely Mn, As, Ni, Cu, Zn, Cr, Co, Mo, and Cd, whereas such affect was not detected for Hg and Pb. The maximum values of the EF were represented by As, minimum values by Hg at all sites. Mean EF values were 36.60 and 0.70 for As and Hg, respectively. This study has clearly assessed a certain level of heavy metal pollution in the region, based particularly on the findings from sediment.
在本研究中，于 2007 年 5 月至 2008 年 11 月期间，在 Kapulukaya 大坝湖的三个不同地点对 13 种元素（Al、Fe、Mn、Cr、Ni、Zn、Co、As、Pb、Cu、Mo、Hg 和 Cd）的浓度进行了测定。Al 的浓度范围为 1.47 至 4.64，Fe（以百分比计）的浓度范围为 0.92 至 3.48，Mn 的浓度范围为 326.60 至 1053.00，Cr 的浓度范围为 98.00 至 1116.00，Ni 的浓度范围为 24.70 至 127.10，Zn 的浓度范围为 14.80 至 124.20，Co 的浓度范围为 11.0 至 43.20，Cu 的浓度范围为 5.00 至 29.30，As 的浓度范围为 9.10 至 69.70，Pb 的浓度范围为 8.60 至 34.00，Mo 的浓度范围为 2.50 至 5.20，Hg 的浓度范围为 1.00 至 1.60，Cd 的浓度范围为 0.50 至 1.80，均为每克干重沉积物中的微克数。根据富集因子和相应的沉积物质量准则，对沉积物的污染程度进行了评估。计算出的富集因子（EF，测量金属与背景浓度之比）表明，人为活动对重金属（Mn、As、Ni、Cu、Zn、Cr、Co、Mo 和 Cd）浓度的影响可以解释大部分重金属的浓度，而 Hg 和 Pb 的浓度则没有受到影响。所有地点的 EF 值最大值均由 As 表示，最小值由 Hg 表示。As 和 Hg 的平均 EF 值分别为 36.60 和 0.70。本研究基于沉积物的发现，明确评估了该地区重金属污染的一定水平。
