The concentration of Acid Leachable Trace Metals (ALTMs) was assessed in urbanized tourist beaches (96 samples from Marina beach, 34 samples from Edward Elliot's beach, and 28 samples from Silver beach) of southeast coast of India. The concentration of metals accumulated in the beach sediment was less than the Upper Continental Crust (UCC) background reference values. The mean enrichment of ALTMs in the studied urban tourist beaches showed the following descending order: Marina beach - Cr > Pb > Ni > Zn > Cu > Mn > Co; Edward Elliot's beach - Cr > Pb > Ni > Mn > Co > Zn > Cu; Silver beach - Cr > Pb > Ni > Co > Mn > Cu > Zn. The ALTMs such as Fe, Mn, Co, Cu, and Zn were probably derived from natural weathering and mild anthropogenic influences whereas other metals were derived from anthropogenic induced factors.
本研究测定了印度东南沿海城市化旅游海滩（Marina 海滩 96 个样本、Edward Elliot 海滩 34 个样本和 Silver 海滩 28 个样本）中酸可提取痕量金属（ALTMs）的浓度。海滩沉积物中金属的积累浓度低于上地壳（UCC）背景参考值。在所研究的城市旅游海滩中，ALTMs 的平均富集程度表现出以下降序排列：Marina 海滩 - Cr > Pb > Ni > Zn > Cu > Mn > Co；Edward Elliot 海滩 - Cr > Pb > Ni > Mn > Co > Zn > Cu；Silver 海滩 - Cr > Pb > Ni > Co > Mn > Cu > Zn。Fe、Mn、Co、Cu 和 Zn 等 ALTMs 可能来源于自然风化和轻度人为影响，而其他金属则来源于人为诱导因素。
