Heavy metal analysis in selected water bodies of Sivakasi town, Tamil Nadu during different seasons

Author(s): C Alagumurugan, Rajan MK
Abstract: The present study was undertaken in Periyar colony and Thiruthangal water bodies in Sivakasi town for analysis of seasonal variations in heavy metals such as lead (Pb), cadmium (Cd), silver (Ag) and copper (Cu). Heavy metal analysis was carried out for a period of two years from June 2014 to May 2016 in four seasons as pre-monsoon, monsoon, early post monsoon and late post monsoon. Concentration of heavy metals Pb, Cd, Ag and Cu were determined by continuous flame method using atomic absorption spectrophotometer. High level of Cd was reported in Thiruthangal water body (0.0220 ppm± 0.72) during monsoon season and during late post monsoon (0.2522 ppm ± 1.43) in Periyar colony. High level of Pb was reported during monsoon (0. 0510 ppm ± 0.93) and low during late post monsoon (0. 0089 ppm ± 0.90). High level of Cu was recorded during late post monsoon (0.0116 ppm ± 0.98) in Periyar colony and during pre-monsoon (0.0159 ppm ± 0.45) season in Thiruthangal water body. Our study revealed that, accumulation of heavy metals such as Cd, Ag, Pb and Cu showed slight variation between the years 2014-2015 and 2015-2016. However, concentrations of some metals are higher during summer season. Concentrations of most of heavy metals in water are observed during monsoon season and this may be mainly due to the addition of heavy metals by run off during monsoon season.
