A conventional method for the quantitative and simultaneous analysis of a large number of pesticides was proposed using a combination of commercial extraction disks and a quartz-fiber disk. Pesticides contained in air were collected on these disks at a flow rate of 10 l min-1 and extracted by acetone. The extracted solution was analyzed quantitatively with GC/MS. In order to evaluate the accuracy of this method, a recovery test was performed. Forty-five kinds of pesticides were spiked on the quartz-fiber disk at a concentration level of 0.2 μg by collecting 10 m3 of clean air. The recovery efficiencies of almost 40 kinds of pesticides showed more than 80%, and the coefficients of variations were less than 20%. The method was applied to a practical environmental analysis of pesticides, and an appropriate result could be obtained.
