光化学烟雾的形成机制

摘要

Environmental problems is the world today confronting the social problems, including environmental pollution and environmental pollution and chemical pollution.Studies show that the cause of environmental pollution is particularly serious, the photochemical smog cause pollution to be neglected.Therefore, the photochemical smog damage to the environment and lands and transformation, with the continuing rapid development of our economy, the fuel consumption increased year by year, the atmosphere, carbon monoxide and carbon compound for pollutant emissions also, these are formed the photochemical smog materials.the photochemical smog once formed, influence, the dangers of the urban environment and human health, the ecological environment balance enormous the very real.Therefore carry out energy reduction policies and control of the atmospheric pollutant emissions must be enforced.Article analyses the photochemical smog the terms and mechanisms, the hazards and control measures.%环境问题是当今世界共同面临的社会问题, 主要包括环境污染和生态污染.研究表明, 化学污染引起的环境污染尤为严重, 光化学烟雾引起的污染不容忽视.因此, 探讨光化学烟雾对环境的危害、迁移和转化规律, 采取行之有效的防治措施显得非常必要.伴随我国经济的持续高速发展, 燃料的消耗量逐年增长, 大气中一氧化碳、氮氧化物及碳氢化物等污染物的排放量也迅速增长, 这些都是形成光化学烟雾的原料.光化学烟雾一旦形成, 影响范围广, 其威害性已对城市环境、人体健康、生态环境平衡造成巨大危胁.因此贯彻节能减排政策, 控制大气污染物排放量势在必行.文章分析了光化学烟雾形成的条件及机理, 阐述了造成的危害和防治措施.
