Air pollution has wide-ranging and deleterious effects on human health and is a major issue for the global community.
The Global Burden of Disease study has described the worldwide impact of air pollution with as many as 3.1 million of 52.8 million all-cause and all-age deaths being attributable to ambient air pollution in the year 2010.
The ozone layer is found in the stratosphere found about 30 miles above the earth.
According to the website The Environment A Global Challenge " The highest regions of the stratosphere contain about 90% of all ozone." (n.p.) The suns rays are absorbed by these ozone molecules, which keeps the rays from reaching the earth. The main pollutant is chlorofluorocarbons (CFCs) which is the major cause of depletion of the ozone layer.
From a health perspective, important components of this mixture include airborne particulate matter (PM) and the gaseous pollutants ozone, nitrogen dioxide (NO are motorized road traffic, power generation, industrial sources, and residential heating.

Secondary pollutants are formed in the atmosphere from other components.Ozone concentrations are highest during the warmest, high-intensity sunlight hours of the day, often showing a broad peak from noon to about 9 pm when many people are outdoors, resulting in significant human exposure.Traffic-related pollutants, such as ultrafine particles and soot, often peak during the morning and evening rush hours, resulting in high exposures for people commuting.Air Pollution is a harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life.One of many forms of air pollution occurs inside homes, schools, offices, in cities , across continents and even globally. Air pollution cause depletion of the ozone layer, which allows a greater amount of ultraviolet rays to earth, that can be harmful for humans.Particles are often classified into three major size groups ( as well, but typically contribute a negligible fraction to the mass, whereas they dominate particle numbers.Resuspension of soil and road dust by wind or moving vehicles, as well as construction work and industrial emissions, result in coarse particles (PM).Moreover, ambient air pollution ranked ninth among the modifiable disease risk factors, being listed above other commonly recognized factors, such as low physical activity, a high-sodium diet, high cholesterol, and drug use.Finally, air pollution accounts for 3.1% of global disability-adjusted life years, an index that measures the time spent in states of reduced health.Some air pollutants return to earth in the form of acid rain , which it can corrode statues and buildings, damage crops, forests, makes lakes, and streams unsuitable for fish and other plant and animal life .Smog is another result from air pollutant which is in the form of fog that is harmful to humans.
