一、氮污染的来源氮是一种相对惰性的气体,但是在某些细菌的作用下或是在石油燃烧、肥料制造过程中,氮能生成一系列活性分子,统称为活性氮。这个分子家族的成员包括氨、硝酸盐离子和氮氧化物。大气中的二氧化氮主要是土壤中的微生物分解含氮化合物产生的。大气中的氮在高温下能氧化成一氧化氮,进而转化为二氧化氮。火山爆发和森林失火 First, the source of nitrogen pollution Nitrogen is a relatively inert gas, but under the action of some bacteria or in the oil combustion, fertilizer manufacturing process, nitrogen can generate a series of active molecules, collectively referred to as reactive nitrogen. Members of this molecular family include ammonia, nitrate ions and nitrogen oxides. Nitrogen dioxide in the atmosphere is mainly produced by microorganisms in the soil that decompose nitrogenous compounds. Atmospheric nitrogen at high temperatures can be oxidized to nitric oxide, and then converted to nitrogen dioxide. Volcanic eruptions and forest fires
