Assessment of Pollution in a Freshwater Lake at Fisher Island, Larsemann Hills over East Antarctica

Pawan Kumar Bharti and U.K. Niyogi

Background and Objectives: The Larsemann Hills area (69°20’-69°28’S, 76°00’–76°30’E) is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, that includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula and several other islands, promontories and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills and the Amery Ice Shelf on the South-Eastern coast of Prydz Bay, Princess Elizabeth Land, East Antarctica. The ice-free area consists of two major peninsulas (Stornes and Broknes), four minor peninsulas and approximately 130 near shore islands. The Larsemann Hills area contains more than 150 lakes at different islands and peninsulas. Methodology: Fisher Island of Larsemann Hills in east Antarctica was selected as a sampling site for the present study. Water sample was collected from a freshwater lake of Fisher Island during 30th Indian Scientific Expedition to Antarctica (ISEA) and analysed for the physico-chemical parameters, major elements and trace metal in surface lake water. Physico-chemical parameters were analysed using standard methodology. Results: The concentrations of metals Cu, Pb, Cd, Zn and Cr were measured using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Pesticide residues were also analysed using GC-MS and LC-MS. Radiation contamination was detected with the help of an automatic and handy radiation detector. Pesticide residues and radiation contamination was found below detection level of instruments in lake water sample. Conclusion: After evaluating general physico-chemical parameters, heavy metals and organic compounds in lake water, it has been observed that the lake water of lake has no pollution load and no impact of any anthropogenic activity.
