AbstractThis study focused on determination of the concentration of selected Organochlorine Pesticides (OCPs) in both particulate matter and gas phase in the Bangkok Metropolitan Region during the dry season 2001-2002. The analyzed samples were collected from 4 sites representing traffic, industry, suburban and mixed areas. The samples were collected by using two different sampling methods paralelly, active and passive, which were set on the roof of the automatic monitoring stations. The active sampling method uses the Anderson-type high volume sampler which can pull the ambient air greater than 300 standard m3 in a 24-hour period. The gaseous phase was trapped by Polyurethane Foam (PUF) adsorbent, and particle phase by Quaiiz Fiber Filter (QFF). The passive sampling method uses the Semipermable Membrane Device (SPMD) which can trap only the gaseous phase of OCPs. The analysis was done by GC/ECD for 16 OCPs compounds following the USEP A Compendium Method T0-4A for active sampling and the SPMD Analytical Guide. The levels of OCPs in the dry season 2001 and 2002 are in order of less than 1 ng/m3 which are lower than the levels in the wet season 2001, possibly due to the higher amount of OCPs applied for pests control during the season. The active sampling method can trap larger numbers of OCPs compounds than the SPMD. However, most of OCPs detected by SPMD were at higher levels than the active sampler. The results of this study can be used to build up a data base and guidelines for the suitable environmental management plan regarding pesticides as air pollutants.
