South Durban basin of South Africa has witnessed tremendous urban, industrial expansion and mass tourism impacts exerting significant pressure over marine environments. 43 sediment samples from 7 different beaches (Bluff beach; Ansteys beach; Brighton beach; Cutting beach; Isipingo beach; Tiger Rocks beach; Amanzimtoti beach) were analyzed for acid leachable metals (ALMs) Fe, Mg, Mn, Cr, Cu, Mo, Ni, Co, Pb, Cd, Zn and Hg. The metal concentrations found in all the beaches were higher than the background reference values (avg. in μgg) for Cr (223-352), Cu (27.67-42.10), Mo (3.11-4.70), Ni (93-118), Co (45.52-52.44), Zn (31.26-57.01) and Hg (1.13-2.36) suggesting the influence of industrial effluents and harbor activities in this region. Calculated geochemical indexes revealed that extreme contamination of Cr and Hg in all the beach sediments and high Cr and Ni levels poses adverse biological effects.
南非南部德班盆地见证了城市和工业的迅猛扩张以及大众旅游业的飞速发展，这些都对海洋环境造成了巨大压力。7 个不同海滩（布拉夫海滩、安斯蒂斯海滩、布莱顿海滩、切割海滩、伊西平戈海滩、虎岩海滩、阿马祖祖蒂海滩）的 43 个沉积物样本被分析了酸可提取金属（ALM）Fe、Mg、Mn、Cr、Cu、Mo、Ni、Co、Pb、Cd、Zn 和 Hg。所有海滩的金属浓度都高于铬（223-352）、铜（27.67-42.10）、钼（3.11-4.70）、镍（93-118）、钴（45.52-52.44）、锌（31.26-57.01）和汞（1.13-2.36）的背景参考值，这表明该地区受到工业废水和港口活动的影响。计算出的地球化学指标表明，所有海滩沉积物中 Cr 和 Hg 的污染程度非常严重，Cr 和 Ni 的含量也很高，这对生物造成了不良影响。
