These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. Because it is located in the atmosphere, air pollution is able to travel easily. As result, air pollution sis global problem and has been the subject of global cooperation and conflict, CAUSES Among the many types of air pollutants are nitrogen oxides, carbon monoxides, and organic compounds that can evaporate and enter the atmosphere-Air pollutants have sources that are both natural and human.
Now, humans nutrient substantially more to the air pollution problem. Forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity are all among the natural causes of air pollution. Usually, natural air pollution does not occur in abundance in particular locations. The pollution is spread around throughout the world, and as a result, poses little threat to the health of people and ecosystems. Though some pollution comes from these natural sources, most pollution is the result of human activity.
The biggest causes are the operation of fossil fuel-burning power plants and automobiles that combustion fuel. Combined, these two sources are responsible for about Of all air pollution in the United Staterooms cities suffer severely because of heavy industrial use of chemicals that cause air pollution. Places like Mexico City and SAA Paulo have some Of the most deadly pollution levels in the world. EFFECTS Air pollution is responsible for major health effects. Every year, the health of countless people is ruined or endangered by air pollution.
Many different chemicals in the air affect the human body in negative ways. Just how sick people will get depends on what chemicals they are exposed to, in what incinerations, and for how long. Studies have estimated that the number of people killed annually in the US alone could be over 50,000. Deer people are highly vulnerable to diseases induced by air pollution. Those with heart or lung disorders are under additional risk, Children and infants are also at serious risk.
Because people are exposed to so many potentially dangerous pollutants, it is often hard to know exactly which pollutants are responsible for causing sickness. Also, because a mixture of different pollutants can intensify sickness, it is often difficult to isolate those pollutants that are at fault. Many diseases could be caused by air pollution without their becoming apparent for a long time. Diseases such as bronchitis, lung cancer, and heart disease may all eventually appear in people exposed to air pollution.
