Assessment of Heavy Metal Pollution in Sediment for Thamiraparani River, India

Abstract

An investigation of sediment characterization was led along a stretch of the Thamiraparani Stream, Tamilnadu, India, during September, 2020 to assess the effect of anthropogenic actions. Ten locations were chosen from Authoor to Punnakayal for the examination. Sediments were analysed with ICP-OES instrument. From the obtained results (stated in mg/kg of dry weight) revealed that Fe wide-ranging from 1623.95 to 53003.83, Pb ranged between 0.02 to 0.3, Zn varies from 0.2 to 2.08, Cu from 0.02 to 0.83, Ni from 0.41 to 2.8, and Mn from 2.01 to 17.39. Assessed Pollution Load Index (PLI) and geo-accumulation index (Igeo) discovered the sediments at all places were almost not affected by metallic element. The obtained results were compared with heavy metal Guidelines for Sediments (EPA).

Effect of pesticide toxicity in aquatic environments: A recent review

“…This pattern of pesticide pollution has been repeatedly observed in studies conducted on other rivers in India like the Ghaggar river in Haryana, Cauvery river in Karnataka and Hindon river in Uttar Pradesh [12,24] . Analysis of pollution in the perennial Tamiraparani river basin in southern India showed the presence of DDT, HCH and 15 other organochlorine pesticide residues exceeding the acceptable limits [29][30] . Contamination of water and sediment samples with organochlorine pesticides residues in surface water and sediments from the Tamiraparani river basin can be explained by the agricultural and municipal outfalls in this region [31] .…”
