Causes of air pollution There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. 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 contribute substantially more to the air pollution problem. Forest fires‚ volcanic eruptions‚ wind erosion‚ pollen dispersal‚

Air Pollution in California In the 1940’s California was supporting a population of seven million people and contained 2.8 million registered vehicles. Within the next twenty years the population more than doubled to reach 16 million while the number of registered vehicles all but tripled increasing to eight million. This has been a common trend in California’s documented history from the early twentieth century to today. There have been many historical and environmental factors that have assisted

Many people think of pollution as the air that we breathe outdoors. Not everyone realizes that the air we breathe indoors is much more polluted. There are pollutants in the atmosphere that have reached a level that is causing a threat to the health of individuals. Pollution began in the early times from the gases of molten volcanic activity being released into the atmosphere. Additional pollutants were caused by the combustion of biomass‚ volatilization of organic compounds‚ and the release of

Ohio is one of the many states that suffer from air pollution. Numbers are rising‚ deaths are occurring and many health risks are involved because of air pollution. Different toxins that are being released into our air cause a great deal of concern because this causes many frequent weather changes as well as population issues. People tend to move away from certain areas located near factories which release massive amounts of pollutants daily. There are land issues as well as waterways where contaminants
