六六六作为杀虫剂应用于农业和卫生上已有三十余年。它的化学性质稳定,易在生物体内蓄积,污染环境,对人有潜在的危害性。一些国家对它采取了不同程度和范围的限用和禁用。 一、食物中六六六残留 据测定六六六广泛残留于各类食物中;在动物的脂肪组织、肝、脑、肾、脾、睾丸、肌肉等器官和血、乳中,以及藻类、浮游生物中均有六六六残留。 在工业品六六六中,所含各异构体比例变动较大。通常,α-六六六占55—70％,β-六六六5—14％,γ-六六六12—15％,δ-六六六6～8％。在使用工业品
For more than thirty years, it has been applied to agriculture and health as a pesticide. Its chemical properties are stable, easy to accumulate in the body, pollute the environment, potentially harmful to humans. Some countries have restricted and banned it to varying degrees and ranges. First, the determination of 666 residues in food It is determined that 666 residues in various types of food widely; in animal fat tissue, liver, brain, kidney, spleen, testis, muscle and other organs and blood, milk, and algae, There are six six six biological residues. In the industrial product BHC, the content of isomers varies greatly. Generally, α-hexacosane accounts for 55-70%, β-hexacos 6 5-14%, γ-hexacoshane 12-15%, δ- hexacosal 6~8%. In the use of industrial products
