Spatial and temporal variations in concentration of dissolved metals viz. Copper (Cu), Lead (Pb), Chromium (Cr), Nickel (Ni), Zinc (Zn), Cadmium (Cd) and Mercury (Hg) in surface waters of southwest coast of India were studied. Concentrations of metals showed an aberration both temporally and spatially. Seasonal average concentrations of the analyzed metals followed the order Zn > Ni > Cu > Pb > Cd > Cr > Hg. The degree of contamination due to metal was determined by comparison with coastal water quality criteria. It established enrichment of Cu, Zn, Ni and Hg due to anthropogenic influence along southwest coast of India.
本研究旨在探讨印度西南海岸表层水中溶解态金属（铜、铅、铬、镍、锌、镉和汞）浓度的时空变化。金属浓度在时空上均表现出异常。分析金属的季节平均浓度顺序为 Zn > Ni > Cu > Pb > Cd > Cr > Hg。通过与沿海水质标准进行比较，确定了金属污染的程度。结果表明，由于人类活动的影响，印度西南海岸的 Cu、Zn、Ni 和 Hg 出现了富集。
