近期,一些地区灰霾、酸雨和光化学烟雾等区域性大气污染问题频繁发生,这些问题的产生都与化石燃料的燃烧、机动车尾气的排放、室内污染空气的排放密切相关,从而使我国大气开始呈现出煤烟和机动车尾气等复合污染的特点。下面就从三个方面来例谈以大气污染为背景的化学试题,供大家参考。一、化石燃料燃烧产生的污染煤、石油等化石燃料是当今世界最重要的能源。煤主要含有碳元素,还含有氢、氧、氮和硫等元素,以及无机矿物质。煤等燃料燃烧 Recently, some regions such as haze, acid rain and photochemical smog and other regional air pollution problems occur frequently, these problems are generated with the combustion of fossil fuels, vehicle exhaust emissions, indoor air pollution is closely related to emissions, so that our atmosphere begins Showing the characteristics of compound pollution such as soot and motor vehicle exhaust. The following three cases to talk about the chemical pollution in the background of the chemical questions for your reference. First, the fossil fuel combustion pollution, coal, petroleum and other fossil fuels is the most important energy in the world today. Coal contains mainly carbon, but also contains hydrogen, oxygen, nitrogen and sulfur and other elements, as well as inorganic minerals. Coal and other fuel combustion
