Hexachlorobutadiene (HCBD) as predominant POPs in Ambient Air : all POPs levels and trends at frequent monitoring super-sites of Japan

摘要

The POPs frequent monitoring of ambient air at the super-site Japan were started on 2009 with high sensitive analysis such as using GC-HRMS and LC-MS/MS by Ministry of the Environment, Japan (MOEJ). 24 POP chemicals (groups) with the exception of dioxins and furans, the analytical methods were established and evaluated as monitoring techniques from frequent monitoring. Data on their short-term spatial variations will contribute to a clarification and understanding of environmental transport and background levels in ambient air.
