摘要

@@ Organochlorine pesticides (OCPs), classified as persistent organic pollutants (POPs),have been banned as pesticides since early 1970s in Japan. Declining trends in atmospheric OCP concentrations began decreasing gradually in recent years, ranging from a few pg/m3 to 1,000 pg/m3, but data related to their nationwide or East Asian distribution in the atmosphere remain sparse. A large-scale passive air sampling survey was therefore conducted across East Asia. Polyurethane foam disks were deployed simultaneously at 54 sites in Japan, 20 sites in China, 30 sites in Korea and 1 site in Taiwan to evaluate OCPs distribution in the atmosphere, during March 21 to May 16, 2008.
