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.
