Abstract :
The study investigates the pollution status of sediment of the Shitalakhya River, Bangladesh. The sediment sample have been collected from five sampling sites of Shitalakshya river and those are analyzed to determine the concentrations of Lead (Pb), Nickel (Ni), Chromium (Cr), Copper (Cu). Samples are digested by aqua regia and analysis is performed by Atomic Absorption Spectrophotometry. Average concentration of Pb, Ni, Cr and Cu have been found 13.29, 22.98, 32.68 and 18.46 mg/kg in sediments respectively. Based on USEPA sediment quality guideline, the sediment samples are not polluted by Pb, however, slightly polluted by Cr, Cu and Ni. Different pollution indices, such as, metal pollution index and Degree of contamination index have also been analysed to identify the pollution status according to various index. Also, the principal component and cluster analysis have been performed. The Risk index suggests that the sediments have low potential risk. Only one principle component was found and all metals have strong correlation to sediment sample contaminants. The Cluster analysis suggests that sediments of Kachpur Bridge (S-2), Shadur Ghat (S-3) and Nabiganj (S-3) are similar and South Rupshi (S-1) and Nabiganj (S-2) are similar based on tested heavy metal contamination
