摘要:A study of River Jhelum was conducted to determine the physico-chemical characteristics of the sediments from June to November 2011, in order to check the effects of effluents coming from Srinagar city on the river sediments at four different sites in River Jhelum. The results revealed that physico-chemical weathering of minerals and anthropogenic activities influence the physico-chemical properties of the sediments. The sediments were slightly alkaline except at site III, where slightly acidic pH was observed. Among the cations Calcium and Potassium were found dominant as compared to Magnesium and Sodium, the overall cationic order being K > Na > Ca > Mg. Among the anions Chloride dominated the Bicarbonates. Total Nitrogen was the highest at site III, and was the lowest at site I. Among the different textural classes sand was found to be dominant and its composition decreased downstream. Overall the physico-chemical parameters of sediments did not show any significant trend among sites, as all the parameters were positively correlated with each other, however, most of the parameters showed peak values at site II and III which were receiving most of the sewage from Srinagar city. Thus the sites located in urban areas were facing more anthropogenic stress than ones located in rural areas.
