市区居民熄灭煤炭等化学燃料发生的烟气，各类工矿企业排放的废气，汽车等机动车辆放出的尾气，都是大气污染物的重要起源。

Urban residents in combustion flue gas generated coal chemical fuel, exhaust gas of various industrial and mining enterprises emissions, exhaust gas released automobile and other motor vehicles, are a major source of atmospheric pollutants.大气污染物的种类很多，环境专家曾经测出有害人体肥壮的挥发无机物就有260多种；其中5种污染物的影响范畴最广，要挟最大，它们是悬浮颗粒物、硫氧化合物、一氧化碳、二氧化碳和氮氧化合物。

Many kinds of air pollutants, environmental experts have detected volatile organic compoundsharmful to human health will have 260 kinds of influence scope; among them 5 kinds of pollutants the most wide, the greatest threat, they are suspended particles, sulfur oxides,carbon monoxide, carbon dioxide and nitrogen oxide compounds.少量排放污染物的结果，大气成分越来越复杂，虽然同大气的重要成分氮、氧相比污染物的浓度少得不幸，常在十万分之一以下，然而它们对环境形成的影响，特意是给人类肥壮和动物成长带来的危害，却是十分重大的。

A large number of emissions of pollutants results, the composition of the atmosphere more and more complex, although the main components of the same atmospheric nitrogen and oxygen concentration of pollutants than less poor, often below 1/, but the impact they have on the environment, especially the growth brings harm to human health and biological,are very serious.依据环球大气污染监测系统最近提供的数据，占环球市区人口差不多一半的居民（约9亿人）不得不在二氧化硫的浓度只能勉强接受或难以接受的大气条件下生存；有约60%的市区人口（共10亿多），生存在烟雾和灰尘等悬浮颗粒物浓度超越规则规范的环境中；大少数国度市区空气中一氧化碳的含量，经常超越环球卫生组织规则的规范。

According to the global atmospheric pollution monitoring system recently available data,accounting for almost half of the world population of urban residents (about people) had in the concentration of sulfur dioxide only marginally acceptable or unacceptableunder atmospheric conditions of life; about 60% of the urban population (10 million), living in the smoke and dust and other suspended particles concentration exceeds the environmental regulations standard; content of carbon monoxide in most cities in the air, often exceeds thestandards set by the world health organization.全环球每天有800人因呼吸受污染的空气而早亡，每年有300多万人死于重要由环境污染——包含大气污染引发的癌症。

The day the world has 800 people affected by pollution from air to breathe and early death,about people died in the main by the environmental pollution -- including theatmospheric pollution caused by the cancer every year.大气污染也使农业大受其害：作物枯败，食粮增产，牲畜中毒，渔业败落，土壤蜕变，森林死亡。

Air pollution also make great harm: the blight of agriculture, food production, poisoning of livestock, fisheries decline, soil deterioration, the forest of death.大气污染还使人们在经济上付出高昂代价。

在美国，仅仅为了消弭大气烟尘所形成的污染，一年中用于修建物从新粉刷所需的费用就高达1亿美元，洗濯纤维品的费用为8亿美元，洗车费用2.4亿美元。

想想看，这还是大气污染形成的直接损失，一个美国便这么多，全环球加在一同该有多少啊！Air pollution also makes people pay a high price in the economy. In the United States, only in order to eliminate the pollution caused by the atmospheric dust, for buildings requiredrepainting costs up to $ a year, washing fiber product costs $, car cost$. Think about it, this is the indirect losses caused by air pollution, a USA is so much, the rest of the world put together how much ah!——大气曾经变成了“废气渣滓箱”。

这个“废气渣滓箱”无异于关上了的“潘多拉的盒子”，不断窜出一只只杀人不眨眼的恶魔。

-- the atmosphere has become waste bins. This waste bins would open up a Pandoras box, from time to time out only kill without spilling blood demon.
