Combinations of 7 adsorbents and 6 extractive solvents were evaluated with collection and extraction efficiencies for measuring 43 pesticides in air by GC/MS. Dichloromethane and acetone were easier to extract such pesticides from the adsorbents. Collection efficiencies of the pesticides on activated carbon fiber paper and ORBO-49P were higher average values and most of them were over 60%. From the results of principal ingredient analyses, the extraction efficiencies show that the 1st factor is characteristics of solvents. Factors of collection efficiencies were considered to be concerned with sampling time and characteristics of the adsorbents. So it is concluded that dichloromethane extraction from activated carbon fiber paper and acetone extraction from ORBO-49P are effective for measuring these airborne pesticides.
