摘要
汞是一种剧毒物质,其在地壳中的含量大约为 5～6 g/kg,主要是以单质的形式存在.汞是一种半金属,以它为原料可以制造水银,即汞和汞合金.自然界中的汞大多以气态形式存在于空气中,少量存在于无机化合物中,在地壳中的含量大约为 0.002%.人体内的汞是从其它金属代谢转化而来,并在血液中循环流动.由于汞具有化学性质稳定、易于降解、生物富集性强和毒性大等特点,因此具有很大的危害性.
Abstract
Mercury is a highly toxic substance,its content in the crust is about 5～6 g/kg,mainly in the form of single quality.Mercury is a semi metallic metal,from which it makes mercury,namely mercury and amalgam.Most of the mercury in nature exists in air in gaseous form,with a small amount in inorganic compounds,containing about 0.002%in the crust.Mercury in the body is metabolized from other metals and circulates in the blood.Due to the stable chemical properties of mercury,easy degradation,strong biological enrichment and great toxicity characteristics,so it has a great harm.
