我国自五十年代初期开始用工业六六六原粉加工成多种六六六制剂,用于防治粮、棉害虫,对农业增产起了重要作用。但是由于六六六有高残留性质,从1974年开始各地区逐步限制了六六六制剂的使用范围,用其他农药取代六六六。主要原因: 一、高残留:六六六在土壤、水域和动、植物体内,降解慢,在人体中也能有一定数量蓄积。据我国医学研究单位研究,证明工业六六六对肝脏有损害。许多国家早已禁用工业六六六,只准使用纯丙体六六六(林丹),並对食品中六六六的残留限量作了严格规定。我国也对农、畜产品规定了残留限量。实践证明在一个地区,单在几种作物上停用六六六,不一定能完全解决六六六的污染问题,有时受附近用药的影响。例如中国农
Since the early 1950s, China started to process a variety of BHC products with 666 industrial raw materials to control grain and cotton pests and play an important role in increasing agricultural output. However, due to the high residue nature of 666, the use of 666 preparations has been gradually reduced in all regions since 1974, replacing 666 with other pesticides. Main reasons: First, the high residue: BHC in the soil, water and animals and plants, slow degradation, but also in the human body can have a certain amount of accumulation. According to the research of medical research institutes in our country, it is proved that industrial 666 causes damage to the liver. Many countries have already banned industrial use of 666 and allowed only the use of purely hexamer BHC (lindane), with strict stipulations on the residues of 666 in food. Our country also stipulates the residual limit for agriculture and animal products. Practice has shown that stopping the use of BHC on a few crops in one area may not completely solve the BHC’s pollution problem and is sometimes affected by the use of nearby medicines. For example, Chinese farmers
