摘要: DDT和六六六(BHC)一类有机氯农药脂溶性强且不易分解,因而具有残效长、易在生物有机体内累积的特点。随着近代工业的高度发展和农业生产的需要,这类农药的踪迹已遍布地理环境的每一个角落。因此,研究 DDT 和 BHC 在地理环境中的迁移、转化过程和残留累积规律,对有效地控制利用这类有机氯农药和保护环境具有很重要的意义。

Abstract: The present article is the result of the investigation in the lower reaches ofthe Jiyun River,which flows through the industrial area that produces organo-chlorine insecticides,and primarily discusses the problem about the distribution,transportation and transformation of DDT and BHC in the lower reaches.According to the result fo the investigation,we hold that:(1) Primarycause for DDT and BHC pollution in local occurrence is the discharge of the pe-sticide factory;(2) Remain ratio of DDT is ten times higher than BHC undersame condition;(3) According to calculation,it shows that DDT is the moststable accumulation pollutant in water body,and yet there is still 35% DDT that maybe transformed into DDD or DDE in the sediment.As far as β-BHC is the moststable BHC isomer in water body,and α-BHC is the easisest to be degradated.
