Deposition of organochlorine pesticides into the surface snow of East Antarctica
Organochlorine pesticides (OCPs) were measured in surface snow collected on a -1400-km inland traverse beginning from the coastal regions of East Antarctica during the Japanese Antarctic Research Expedition (JARE) of 2007/2008. Of the 22 OCPs, alpha-hexachlorocyclohexane (HCH), gamma-HCH, and hexach...
