Six criteria pollutants monitored by the EPA:

Ground-Level Ozone

Carbon Monoxide

Sulfur Dioxide

Nitrogen Dioxide

Lead

Particulate Matter

Each pollutant is linked to the EPA website where specific information about each pollutant can be found.

The National Ambient Air Quality Standards (NAAQS) sets the standards on the levels of these pollutants that is safe for the environment. This link gives the standards for the six air pollutants.

Problems From Air Pollutants - The Environment

# data[].attributes.body
Ozone affects the sensitive vegetation in forests and wilderness areas especially during growing season

Carbon monoxide does not have large environmental problems as it mostly effects human health

Sulfur dioxide can damage trees and plants by harming leaves and growth; contributes to acid rain

Nitrogen dioxide can interact with water to cause aide rain and make the air hazy

Particulate Matter mainly contributes to the haze which cause less visibility

Lead can lead to less growth in plants and animals as well as affect their reproductive rates

Problems From Air Pollutants - Human Health

# data[].attributes.body
Ozone can cause chest pain, cough, throat irritation, inflammation of airways and/or lungs

Carbon monoxide can reduce the oxygen that gets delivered to the brain or heart; thus causing dizziness or confusion

Sulfur dioxide harms the respiratory system and greatly effects those with asthma

Nitrogen dioxide harms the respiratory system causing coughing or wheezing, especially in those with asthma

Particulate Matter can get stuck in lungs and causes serious health problems related to breathing

Lead can affect many important systems of the body such as the digestive, developmental, and immune systems

People all over the world suffer from long term and short term effects of air pollution. Currently, more children are being diagnosed with asthma and are becoming more sensitive to air pollutants. Also, it is affecting the way we live and our quality of life. The more air pollution in the air, the more environment that will be destroyed; and we won't be able to get it back.
Air pollutants are also causing global warming and damage to the stratospheric ozone, which protects us from the harmful UV rays from the sun. It is important for us to find other sources of energy and find ways to limit what we put into the air. Additionally, the EPA is important in creating federal policies for air quality and takes measures to assist the country in finding ways to limit emissions.

There are many solutions to reducing your contributions to air pollution.

Carpool, use public transit, or bike/walk

Conserve energy by turning off lights, limiting appliance use

Avoid burning trash or leaves

The EPA also has many regulations from the Clean Air Act that help to keep pollutant levels under control

Transportation and vehicle standards

Visibility rules with respect to haze from particulate matter
