A method using SOXHLET, extracted liquid and Vortex Nitrogen Sweeping as its sample pretreatment method has been developed for the determination of 17 organochlorine pesticide residues in Atmosphere by GC-ECD standard curve. This method determinated blank spike precision and accuracy, and spiked standards precision and accuracy. The results showed that blank spike precision was from 7.4% to 19.5%, accuracy was from 81.7% to 114%. The detection limit estimation was from 0.06 ng/m3 to 0.23 ng/m3 in the air.
