有机氯农药残留及分布状况.结果表明:稻田土壤中残留的有机氯农药主要为六六六(HCHs)和滴滴涕(DDTs)类,共占有机氯农药残留总量的84.6%,
本标准规定了测定土壤和沉积物中有机氯农药的气相色谱法。本标准适用于土壤和沉积物中α-六六六、六氯苯、γ-六六六、β-六六六、δ-六六六、硫丹I、艾氏剂、硫丹Ⅱ、环氧七氯、外环氧七氯、o,p′-滴滴伊、γ-氯丹、α-氯丹、反式-九氯、p,p′-滴滴伊、o,p′-滴滴滴、狄氏剂、异狄氏剂、o,p′-滴滴涕、p,p′-滴滴滴、顺式-九氯、p,p′-滴滴涕、灭蚁灵等23种有机氯农药的测定。其他有机氯农药若通过验证，也可采用本标准测定。当取样量为10.0g时，23种有机氯农药的方法检出限为0.04μg/kg～0.09μg/kg，测定下限为0.16μg/kg～0.36μg/kg。详
浩瀚色谱（山东）应用技术开发有限公司，采用气相色谱测定土壤中的痕量半挥发性有机氯农药.有机氯农药(α-HCH、β-HCH、γ-HCH、δ-HCH、七氯、艾氏剂、环氧七氯、硫丹Ⅰ、p,p'-DDE、狄氏剂、异狄氏剂、硫丹Ⅱ、p,p'-DDD、o,p'-DDT、异狄氏剂醛、硫丹硫酸酯、p,p'-DDT、甲氧滴滴涕)的回收率在87.56%～124.22%.
在安捷伦，岛津，赛默飞，瓦里安，布鲁克，PE/磐诺等仪器上测定有机氯农残，分离良好，面积外标法定量，结果满意。

Residue and distribution of organochlorine pesticides The results showed that the residual organochlorine pesticides in paddy soil were mainly composed of hexachlorocyclohexane (HCHs) and DDT, accounting for 84.6% of the total organochlorine pesticide residues,
This standard specifies the gas chromatography method for determining organochlorine pesticides in soil and sediment. This standard is applicable to the determination of 23 organochlorine pesticides in soil and sediment, including alpha hexachlorocyclohexane, hexachlorobenzene, gamma hexachlorocyclohexane, beta hexachlorocyclohexane, delta hexachlorocyclohexane, endosulfan I, aldrin, endosulfan II, epoxyheptachloride, epoxyheptachloride, o, p '- diquat, gamma chlordane, alpha chlordane, trans nonachloride, p, p' - diquat, o, p '- diquat, dieldrin, endrin, o, p' - DDT, p, p '- diquat, cis nonachloride, p, p' - DDT, and imidacloprid. If other organochlorine pesticides pass validation, this standard can also be used for determination. When the sampling amount is 10.0g, the detection limit of 23 organochlorine pesticides is 0.04 μ g/kg to 0.09 μ g/kg, and the lower limit of determination is 0.16 μ g/kg to 0.36 μ g/kg. detailed
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography to determine trace amounts of semi volatile organic chlorine pesticides in soil Organochlorine pesticides (α - HCH, β - HCH, γ - HCH, δ - HCH, heptachlor, aldrin, epoxyheptachlor, endosulfan I) p,p'-DDE、 Dieldrin, Endrin, Endosulfan II p,p'-DDD、o,p'-DDT、 Endrin aldehyde, endosulfate p,p'-DDT、 The recovery rate of methoxy DDT ranges from 87.56% to 124.22%
Organic chlorine pesticide residues were determined on instruments such as Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, PE/Panno, etc. The separation was good, and the quantitative results were satisfactory using the area external standard method.
