Progress in Detection Technology of Organochlorine Pesticide Residues in Soil

Organochlorine pesticide residues are widely concerned by the public.Current situation of pesticide residue detection technology was analyzed，and development trends of new technology were given.Accuracy of detecting organochlorine by mass spectrometry and chromatography was relatively low，respectively.With progress of technology，pretreatment and detection of organic chlorine has been made a breakthrough and improved.Integrated coupling technology of extraction and purification has improved pretreatment efficiency.Combined use of various detection technologies could make results more accurate and efficient and make detection limit lower.
