An overview of POP levels and trends in Antarctic trophic webs: a starting point for future research
Contamination in the Antarctic ecosystems was first reported in 1966 and there has been an increasing interest in studying the presence of pollutants in this pristine polar region since then. This awareness has been growing in recent years, as the Arctic has been reported as a final sink for persist...
