震惊世界的日本东京毒气杀人事件给人们留下的印象是深刻的。据悉,导致这一事件的毒气是“沙林”。沙林,学名为甲氟磷酸异丙酯,本世纪30年代第二次世界大战前夕发明于德国,最初用于农药,后由纳粹进一步开发成化学武器。沙林为稻草色液体,易于在常温下蒸发气化,它本身没有气味,只有与其他化学物质混合之后才会产生气味。沙林类似于杀虫剂马拉硫磷,但毒性更强烈,其作用对象是在人体神经交汇处传递神经细胞间脉冲信号的胆碱酯酶。液态沙林滴在皮肤上一滴就足以致人死命;但空气中弥散的沙林蒸气通过呼吸道进入到人体内之后的危害更大,是这种毒剂对生命构成最大威胁的途径。
The shock to the world Japan’s Tokyo gas murders left a deep impression on people. It is reported that the poison that led to this incident is “Sarin.” Sarin, whose scientific name is isopropyl isophthalate, was invented in Germany on the eve of the Second World War in the 1930s and was initially used in pesticides and further developed into a chemical weapon by the Nazis. Sarin is a straw-colored liquid that is easily evaporated and vaporized at room temperature. It is odorless in itself and does not smell unless mixed with other chemicals. Sarin is similar to the insecticide malathion, but more toxic, its role is to cholinesterase transmission of pulse signals between nerve cells at the intersection of human nerves. Drops of liquid sarin on the skin are enough to cause human death; however, the sarin vapor diffused through the air into the human body through the respiratory tract is even more detrimental and constitutes the greatest threat to life.
