Abstract :

<p>Trace element analyses were carried out in South Chennai coastal area, and its concentration (Fe, Mn, Cu, Cr, Zn, Pb, Ni, Co) in groundwater were quantified. Totally, fifty groundwater samples were collected during pre and post&ndash;monsoon of the year 2014&ndash;2015 and analyzed in Atomic Absorption Spectroscopy (AAS). The analytical results were compared with Bureau of Indian Standards (BIS, 2012). The Cu concentrations were above permissible limit in Pudhupakkam, Sathankuppam, Vanuvampettai, Chromepet, Vengadamangalam, Sirucheri, Palavakkakuppam and Chinnadikuppam during both seasons. In Thiruvanmiyur, Guindy, Sathankuppam and Pallavaram locations Cr value was observed to be above permissible limit. The Fe concentrations were observed to be above permissible limit in Palavakkam, Sathankuppam, Vanuvampettai and B.V. Nagar locations. In Kumenan Nagar, and Besant Nagar locations Mn concentration were above the permissible limit. Health hazards that are related to Cu, Cr, Fe and Mn are given. The other trace elements concentrations in groundwater of the study area were within the permissible limit</p>
