FC: Rayah Baldwin Kelsie Thompson | Air Pollution

1: Description | - Air pollution is a mixture of natural and man made substances in the air we breathe. - Such as fine particles produced by burning fossil fuels, ground level ozone, which is a reactive form of oxygen that is a primary component of urban smog, and noxious gases such as sulfur dioxide, nitrogen oxides, carbon monoxide, and chemical vapors. - The health of air pollution have been reported in research studies over the past 30 years. -Effects include respiratory diseases such as asthma, cardiovascular diseases, changes in lung function, and death. -There is also evidence of exposure to air pollution can have long-term effects on lung development in children.

2: Causes | Air pollution is caused by a wide variety of things. The earth is great at cleaning the air on its own. However, air pollution has grown so much, the earth can no longer clean all of it. This is starting to have a many effects on the environment. Such as causing acid rain, smog, and a wide variety of heath problems. Some causes of air pollution is cars, trucks, jet airplanes, and other combustion engine vehicles. The exhaust from these contain carbon monoxide, nitrous oxide, and gaseous oxide. This type of air pollution creates smog which causes respiratory health problems and holes in the ozone layer which increases the exposure to the suns harmful rays.

3: The burning of oil and coal which are fossil fuels also contribute to smog like in China and LA. Pesticides used to kill indoor and outdoor pests insecticides to kill them all cause air pollution do to the chemicals they release. Mining is another cause of air pollution because as the people drill and blast the coal it releases chemicals such as Methane Sulfur dioxide and Oxide of Nitrogen as well as Carbon monoxide.

4: Acid rain is an environmental cause from air pollution. Air pollution has many effects on wildlife. Toxic pollutants in the air or deposited on soils or surface waters can impact wildlife in many ways. Like humans animals can have health problems if they are exposed to air toxic over time. Studies show that air toxics are contributing to birth defects, reproductive failure, and diseases in animals. Air pollution also impacts our ozone it allows more harmful rays to entire earths atmosphere. It effects our climate it messes up the delicate balance in our atmosphere. | Effects on Environment

6: Stopping Air Pollution | Air pollution control act of 1955 which was the nations first piece of federal legislation dealing with air pollution. It identified air pollution as a national problem and announced that research and additional steps to improved the situation needed to be taken. Clean air act of 1963 dealt with reducing air pollution by setting emissions standards for stationary sources such as Power plants and Steel mills. Did not take into account mobile sources. Amendments to the clean air act were passed in 1965, 1966, 1967, and 1969. They authorized the secretary of health common welfare and education to set standards for auto emissions expanded local air pollution control programs, established air quality control regions, set air quality standards and compliance deadlines for stationary source emissions, and authorized research on low emissions fuels and automobiles

7: The Clean Air Act of 1970 was a major revision and set much more demanding standards. It established new primary and secondary standards for ambient air quality,new limits on emissions and increased research funds. The Clean Air Act of 1990 Addressed five main areas: air-quality standards, motor vehicle emissions and alternative fuels, toxic air pollutants, acid rain, and stratospheric ozone depletion.
