[目的]确定玉米对土壤中老化滴滴涕和六六六的累积、迁移和转化能力。[方法]温室盆栽试验。取均匀掺入梯度浓度滴滴涕和六六六农药的科研土壤装盆,收集持续盆栽过程中不同时段的土壤和植物样品进行残留测试。[结果]所选择的玉米植株在所设计的土壤污染浓度范围内具有宽域的滴滴涕和六氯环己烷清除能力,其茎秆、根系的生物浓缩系数分别介于0.004至0.027和0.036到0.097之间,但去除率均低于0.1,滴滴涕和六六六梯度处理间无显著差异。滴滴涕可通过被动吸附和主动吸收被玉米植体积累,且由还原性脱卤化介导,p,p’-DDT向p,p’-DDE转化。[结论]玉米对土壤有机氯农药具有清除修复能力,且有机氯农药的对玉米脂肪的亲和力是影响其在植物体内的吸收和转运的主要因素之一。 [Objective] To determine the accumulation, migration and transformation ability of corn on DDT and BHC in the soil. [Method] greenhouse pot experiment. Soil and plant samples collected from different periods of continuous potting were collected for residual testing by collecting soil from scientific research soils uniformly mixed with DDT and BHC pesticides. [Result] The selected corn plants had a wide range of DDT and HCH removal ability in the range of designed soil pollution concentration. The bioconcentration coefficients of stems and roots ranged from 0.004 to 0.027 and from 0.036 to 0.097 , But the removal rates were lower than 0.1, there was no significant difference between DDT and BHC treatment. DDT is converted into p, p’-DDE by passive adsorption and active absorption by corn plants and mediated by reductive dehalogenation. [Conclusion] Corn had the capability of removing and repairing soil organic chlorine pesticides. And the affinity of organochlorine pesticides to corn fat was one of the main factors affecting its absorption and transport in plants.
