Hexachlorocyclohexane, a saturated compound formed by the substitution of a hydrogen atom on each carbon atom of cyclohexane with a chlorine atom. English referred to as BHC. Molecular formula C6H6Cl6. Structure due to molecular carbon, hydrogen, chlorine atoms of the 6, can be seen as the benzene of the six chlorine addition products. White crystals, there are eight kinds of isomers. 666 pairs of insects have contact to kill, smoked and stomach poisoning effect, in which the gamma isomer insecticidal effect of high ***, a isomer, followed by the δ isomer, β isomer efficiency is extremely low. Hexachlorobenzene on acid stability in alkaline solution or in the presence of zinc, iron, tin, easy to decompose, long-term moisture or sun will fail.
DDT, and for DDT, scientific name double p-chlorophenyl trichloroethane (Dichloro-Diphenyl-Trichloroethane), the chemical formula: (ClC6H4) 2CH (CCl3). White crystal, insoluble in water, soluble in kerosene, can be made into emulsion, low toxicity to humans, was once the famous synthetic pesticides and pesticides. DDT was later found to be difficult to degrade, accumulate in fish and birds, and destroy the ecological balance. Therefore, DDT has been discontinued in most parts of the world, and only a few areas continue to be used against malaria.

六六六即六氯环己烷，是环己烷每个碳原子上的一个氢原子被氯原子取代形成的饱和化合物。英文简称BHC。分子式C6H6Cl6。结构式因分子中含碳、氢、氯原子各6个，可以看作是苯的六个氯原子加成产物。白色晶体，有8种同分异构体。666对昆虫有触杀、熏杀和胃毒作用，其中γ异构体杀虫效力***高，a异构体次之，δ异构体又次之，β异构体效率极低。六氯化苯对酸稳定，在碱性溶液中或锌、铁、锡等存在下易分解，长期受潮或日晒会失效。
DDT，又作滴滴涕，学名双对氯苯基三氯乙烷（Dichloro-Diphenyl-Trichloroethane），化学式：(ClC₆H₄)₂CH(CCl₃)。白色晶体，不溶于水，溶于煤油，可制成乳剂，对人类毒性低，曾经是***的合成农药和杀虫剂。后来人们发现DDT不易降解，积累下来对鱼类和鸟类生存繁殖不利，破坏生态平衡，因此在世界大部分地区已经停止使用DDT，只有少数地区继续使用以对抗疟疾。
