Brief Description (Abstract):

Sampling of aerosols was carried out at two East Antarctic sites during 20th January to 3rd February 2009 at Larsemann Hills (LH) and 23rd February - 7th March 2009 near Maitri station at Schirmarcher Oasis (SO), using a high volume sampler. The elemental concentration was analyzed through Ion Chromatography. Sea salt aerosol (Na) dominated the elements forming 90-92% of the total elemental mass concentration. Crustal aerosols were enriched with Sc and Co whereas Mo, Cd, Sb enrichment in aerosols indicated anthropogenic sources in both the study regions. Further, the Efc of Pb showed crustal source in Larsemann Hills but anthropogenic influence in aerosols near Maitri at Schirmarcher Oasis. During blizzards, the aerosols were found to be enriched with anthropogenic elements like Cd, Mo and Cu at both the sampling sites.

Status: Completed

Purpose: This study not only draws a comparative analysis of aerosols at two east Antarctic sites but also provides the baseline data on aerosol trace elemental concentration before the third Indian Antarctic station, Bharati was commissioned at Larsemann hills.
