WHAT IS POLLUTION
There are many kinds of air pollution. The Environmental Protection Agency (EPA) calculates the Air Quality Index (AQI) for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide, and nitrogen dioxide. Ozone and particle pollution are two common pollutants found in many parts of the country.
Ozone is a colorless odorless gas. It’s the same kind of gas that’s found in the ozone layer. But in the ozone layer – high in the Earth’s stratosphere – ozone protects us from the sun. At ground level, where we live, ozone pollution is unhealthy to breathe. Ground-level ozone forms when pollutants from cars, trucks, power plants, industries, and some consumer products “cook” in the sun. Ozone usually peaks during the afternoon hours, when sunlight is the most intense.More about ozone.
Particle pollution, also called particulate matter, consists of microscopic particles in the air. It can be a problem in the winter or summer, depending on where you live. Particle pollution causes haze, blurring the view in many cities and national parks. And like ozone, it’s not healthy to breathe. More about particle pollution

WHAT CAUSES AIR POLLUTION!!
1.Vehicle exhaust emissions are the major human-produced air pollution in South-east Queensland; up to 72% of all pollutants. Lead is also released to the air from vehicles using leaded petrol (Super), although this is decreasing as more cars use unleaded petrol.
2. 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 There are many different chemical substances that contribute to air 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, 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 combust fuel. Combined, these two sources are responsible for about 90% of all air pollution in the United States.
Some cities suffer severely because of heavy industrial use of chemicals that cause air pollution. Places like Mexico City and Sao Paulo have some of the most deadly pollution levels in the world.
3. We cause air pollution directly through our use of electricity, fuels, and transportation.
We also cause air pollution indirectly, when we buy goods and services that use energy in their production and delivery. Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles.
Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result. Using carbon dioxide as an example, the average family in the United States causes air pollution in the following ways:






What are rhe effects
1. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics. People who exercise outdoors, for example, on hot, smoggy days increase their exposure to pollutants in the air.
The health effects caused by air pollutants may range from subtle biochemical and physiological changes to difficulty breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and even premature death.
