Seasonal variation of heavy metals in Vellar estuary, South East Coast of India, Tamilnadu

  K.Shameem Rani

In the present research work, the heavy metal contamination in Vellar estuary, South east coastal of India were evaluated in this study, heavy metals such as copper, zinc, lead, iron, chromium and cadmium were analyzed in the water samples. The metals concentration in water during the present study period showed pronounced spatio-temporal variations. The spatio- temporal variations of heavy metals at different stations were due to the variations in point sources. Occurrence of higher levels of heavy metals at all the three stations may be due to agricultural runoff, effluent discharge from the discharge of tanneries and distilleries at the upstream of the river and to the air-borne automobile emissions due to the recently developed East Coast Road (ECR). The sample analysis was done by acid digestion and atomic adsorption spectrophotometer (AAS).

Keywords- Key words: Vellar estuary, Heavy metals and Atomic Absorption Spectrophotometry (AAS).
