酸沉降分子式：CAS号：性质：又称酸性(降)雨，有时代称酸沉降。通常指pH值<5.6的雨雪或其他形式的大气降水(如雾、露、霜等)。纯净的雨雪降落时，自然大气中的二氧化碳溶入其中形成碳酸而具弱酸性，pH值达5.6；故把pH值>5.6的降水，作为非污染或不酸的降水；pH值<4多为人为的强酸性物质造成的。如燃煤燃油排放的二氧化硫、氮氧化物，在大气中转化成硫酸、硝酸或其盐类，造成环境与生态的成危害。水体酸化后，会导致水生生物的组成结构变化和鱼类的死亡，西欧、北美许多湖的酸化而无鱼生存。酸雨还会造成森林毁坏、金属结构和建筑物的腐蚀。预防酸雨，主要是采用低硫优质煤，发电厂和钢铁厂等大型工业采用脱硫、脱硝技术，以降低二氧化硫和氮氧化物的排放量；改善汽车发动机的燃烧条件或用尾气脱硝装置，以降低氮氧化物的排放。
