Anthropogenic activity in east Antarctica has increased since the last 2-3 decades because of the various scientific expeditions. Additionally, global pollution due to various newly introduced pollutants like pesticides is on use since the past century and many factors contribute to contamination even in Antarctica. Persistent Organic Pollutants (POP’s) are semi-volatile, toxic organic compounds which resist photolytic, chemical and biological degradation. POP’s are persistence in nature and includes some pesticides, PCB’s and dioxins. Due to volatile nature these contaminate are transported across the earth by “grasshopper effect”. The study reported the occurrence of several POP’s in the lake water samples which were collected from Grovnes peninsula, Larsemann Hills, East Antarctica. A total of 45 lake water samples from fifteen different selected locations were collected, during 34th Indian Scientific Expedition to Antarctica (ISEA) in austral summer of 2014 to 2015. In these samples, twenty-seven compounds of POP’s were estimated. POP’s residue levels were found in the lake water samples from 10.00 pg/mL - 75.00 pg/mL in fifteen different lakes. Presence of p,p’-DDT was detected in all different lakes but high concentration found in L1E NG & L5 SG lake water. It has been observed that the lakes of Grovnes peninsula have a trace amount of POP’s and it is an alarming situation which needs to be investigated further to maintain the pristine environment in Antarctica. The presence of POP’s may be attributed to orographic effects, migratory birds, bio magnification and anthropogenic sources.
