Trace element concentration in the beach placer mining areas of Kanyakumari coast, South India was assessed. Sewage and contaminated sediments from mining sites has contaminated the surface sediments. Enrichment factor indicates moderately severe enrichment for Pb, minor enrichment for Mn, Zn, Ni, Fe and no enrichment for Cr and Cu. The Igeo values show higher concentration of Pb ranging in the scale of 3-4, which shows strong contamination due to high anthropogenic activity such as mining and terrestrial influences into the coastal regions. Correlation coefficient shows that most of the elements are associated with each other except Ni and Pb. Factor analysis reveals that Mn, Zn, Fe, Cr, Pb and Cu are having a significant loading and it indicates that these elements are mainly derived from similar origin. The cluster analysis clearly indicated that the mining areas are grouped under cluster 2 and non-mining areas are clustered under group 1.
对印度南部坎亚库马里海岸海滩砂矿开采区的微量元素浓度进行了评估。来自采矿场地的污水和受污染沉积物已污染了表层沉积物。富集因子表明，铅为中度严重富集，锰、锌、镍、铁为轻度富集，铬和铜无富集。地积累指数值显示铅的浓度较高，范围在3 - 4级，这表明由于采矿等高强度人为活动以及陆地对沿海地区的影响，存在强烈污染。相关系数表明，除镍和铅外，大多数元素彼此相关。因子分析显示，锰、锌、铁、铬、铅和铜具有显著载荷，这表明这些元素主要源自相似的来源。聚类分析清楚地表明，采矿区归为第2类，非采矿区归为第1类。
