自1982年成立以来，Alang-Sosiya船厂已成为世界上最大的船舶拆解工厂。每年都有几百艘船到达这里。研究了这个拆船厂潮间带的大块和细粒沉积物的重金属污染程度，拆船厂有两个站点，一个在距离5公里的两侧，另一个参考站点在靠近Mahuva的60公里处，向南。样品采用全消化技术，分析了Cd、Co、Cu、Cr、Fe、Mn、Ni、Pb、Zn、Al和%TOC元素。金属绝对浓度反映了BF和FF沉积物样品中有机质含量的变化。计算了富集系数（EF）和地质堆积指数（Igeo），并对这些地点的相对污染水平进行了评价。在Alang-Sosiya，观察到重金属的富集程度相对较高。
Since its inception in 1982, the Alang–Sosiya yard has become the largest ship scrapping works in the world. Several hundreds of ships arrive every year. The degree of heavy metal contamination has been studied in bulk and fine sediments from the intertidal zone of this ship scrapping yard, two stations, one on either side at 5 km distance and one reference station 60 km distance near Mahuva, towards the south. The samples have been subjected to a total digestion technique and analysed for elements: Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Zn and Al, and %TOC. The absolute metal concentrations reflected variations in BF and FF sediment samples with organic matter content. Enrichment factors (EF) and geoaccumulation indices (Igeo) have been calculated and the relative contamination levels are assessed at these sites. At Alang–Sosiya, the enrichment of heavy metals has been observed to be relatively high.
