对福建省１０８个有代表性的茶园有机氯农药六六六（ＢＨＣ）、滴滴涕（ＤＤＴ）残留量现状进行调查，共采茶树鲜叶、土样和背景土样３４４个．分析结果表明：（１）ＢＨＣ在茶树及土壤中分布均匀，且主要残留于土壤中，但均已自然降解到较低水平；ＤＤＴ主要残留于树体，茶树与土壤中的分布有明显差异．ＢＨＣ污染来自以往施药所致，ＤＤＴ污染主要是８０年代引起，ＤＤＴ残留量高于ＢＨＣ．（２）名贵品种种植园土壤ＤＤＴ残留量比一般品种园高，但其叶片农药残留量却比一般品种园低．（３）各品种茶树叶片及其种植土壤农药残留量均与树龄、海拔高度、土壤深度等有一定相关 A total of 344 fresh leaves, soil samples and background soil samples from 108 representative tea plantation organochlorine pesticide residues (BHC) and DDT residues in Fujian Province were investigated. The results showed that: (1) BHC was evenly distributed in tea plants and soil, and mainly remained in the soil, but both of them were naturally degraded to a lower level. DDT mainly remained in the tree body and the distribution of tea tree and soil was significantly different. BHC pollution from the past due to pesticides, DDT pollution was mainly caused in the 1980s, DDT residues higher than the BHC. (2) The residues of DDT in valuable cultivated plantation soils were higher than those in common cultivars, but the residual pesticide residues in leaves were lower than those in common cultivars. (3) The leaf residues of tea plants and their pesticide residues in soils were all related to their age, altitude and soil depth
