The volatile metals like Hg and Pb introduce to the atmosphere mostly through burning of fossil fuel. Generally, the distribution of mercury in environmental media is related to pH, oxygen content, organic matter, reducing agents and microbial activity. In this paper we report for the first time, observed concentration of total dissolved mercury in the water samples. Water samples were collected during the austral summer of 2009 from lakes of Schirmacher Hills, and Larsemann Hills- the two sites of Indian research stations in Antarctica. Mercury was determined using a Cold Vapor Atomic Absorption Spectroscopy (CVAAS) method. The results show that mercury distribution varies in the range of 0.063-0.56 ?gL-1 in lakes of Schirmacher Hills and 0.27-0.72 ?gL-1 in lakes of Larsemann Hills ?gL-1. The main objective of this study was to evaluate the concentration of total mercury in the lakes of Schirmacher Hills and Larsemann Hills.
