World Health Organization and the United Nations Environment Organization issued a report, said: "Air pollution has become the worlds urban population lives in an inescapable reality." If human beings living in the air pollution is very serious, it will be in a few minutes all died. Industrial civilization and urban development, creating great wealth for mankind, but also taking into account the billions of tons of emissions and waste discharged into the atmosphere, the atmosphere of human beings has become the air and toxic waste repository libraries. Therefore, the atmosphere of harmful gases and pollutants reaches a certain concentration, the effects on humans and the environment a huge disaster.

    An atmospheric pollution on human health and harm air pollutants harmful to human mainly through three channels: one is hurt after contact surface of the body, the second is atmospheric pollutants containing edible food and water poisoning, three is the inhalation of contaminated air troubles various serious diseases. From the table below, you can see: a variety of atmospheric pollutants enter the body through a variety of ways, the effect on human health is multifaceted. Moreover, the harm is extremely serious.

     Second, the atmospheric pollution hazards of biological survival and development of air pollution mainly through three channels endanger the survival and growth of organisms: First, depletion of biological poisoning or death, the second is to slow the normal development of the three is to reduce biological resilience against pests capability. Plants in the growing season and long-term contact with atmospheric pollution, damage the foliage, weakening the photosynthesis; hurt the internal structure, the plants wither, until death. A variety of harmful gases, sulfur dioxide, chlorine and hydrogen fluoride damaging the plants. Atmospheric pollution damage to animals, mainly respiratory infections and consumption of food contaminated by the atmosphere. Among them, arsenic, fluorine, lead, molybdenum and other hazards max. Atmospheric pollution weaken the animal body, and even death. Form acid rain, air pollution also kills microbial, making soil acidification, reduced soil fertility, harm to crops and forests.

    Third, the corrosion of air pollution on atmospheric pollutants on the object apparatus, equipment and buildings, which have corrosion. Rust occurs like metal buildings, relics severe weathering.

    Four, atmospheric pollution on the environmental impact of the global atmosphere atmospheric pollution has been in development beyond the borders, the harm throughout the world. The impact on the global atmosphere evident in three aspects: First, ozone depletion, acid rain corrosion second, third, global warming

 1 appears over the Antarctic ozone hole in the ground 10-55 km in the stratosphere, the relative concentration of ozone in the atmosphere, forming the ozone layer. With the ozone layer in the atmosphere, air purification and sterilization plays a role, you can put most of the harmful ultraviolet rays are filtered out, reducing the harm to human body, but also a lot of crop production. Make the body too thick ozone poisoning, while reducing ozone levels, ultraviolet to drive straight, so that the increased incidence of skin cancer, crop production. Scientists have found that ozone depletion over the north and south poles, as if the sky collapsed a hollow, called "ozone hole." Ultraviolet light through the "ozone hole" into the atmosphere, crimes against humanity and other creatures of nature. "Ozone hole" appears, with the widespread use of Freon (refrigerators, air conditioners and other cooling material). Now, the United States and Europe and other countries decided that from 2000 onwards, to stop production of Freon.

2 the harm to the world of acid rain acid rain damage spread throughout Europe and North America, China are mainly distributed in Guiyang, Chongqing and Liuzhou and other places. After the rain down to the ground, resulting in deterioration of water quality on a variety of aquatic animals and plants are threatened with death. Plant leaves and roots to absorb a large number of acidic substances, caused withered and died. Acid rain enters the soil, so that soil fertility decline. Long-term human lives in acid rain, drinking acidic water, can cause respiratory, kidney disease and cancer and a series of diseases. It is estimated that acid rain each year claiming 7500-12000 lives.

    3. "Greenhouse effect" serious consequences around the earth we live, wrapped in a thick layer of the atmosphere, forming an invisible "glass house" in the earth produced a similar glass greenhouse effect. Originally, the "greenhouse effect" is normal. However, to enter the industrial revolution, due to human burning of coal, oil and natural gas and other fuels, carbon dioxide levels in the atmosphere surge, "glass house" in the amount of absorbed solar energy also increases. Thus, in the earth produce droughts, heat waves, tropical storms and rising sea levels and a series of severe natural disasters, human caused huge threat
