SPATIAL AND TEMPORAL PATTERN OF ORGANOCHLORINE AND CURRENTUSE PESTICIDES IN THE GLOBAL ATMOSPHERE

摘要

Introduction In the past organochlorine pesticides (OCPs) were used intensively around the world in agriculture and also to control vector borne diseases. Because these pesticides were found to persist in the environment and to bioaccumulate in the food chain, many industrialized countries banned or restricted the use of legacy OCPs in the 1970s. Eventually, the Stockholm Convention on Persistent Organic Pollutants (POPs) led to world-wide bans and restrictions on OCPs (aldrin, endrin, dieldrin, heptachlor, chlordane, mirex, toxaphene, DDT and hexachlorobenzene (HCB), and more recently on hexachlorocyclohexanes (HCHs)). Less persistent pesticides continue to be used in large quantities and are often referred to as current use pesticides (CUPs).
