6 common pollutants
1. Ozone- Ozone is a gas composed of three oxygen atoms. It isn’t usually emitted directly into the air, but at ground level is created by a chemical reaction between oxides of nitrogen and volatile organic compounds in the presence of heat and sunlight.
Concerns:
-Triggers a variety of health problems even at very low levels
-May cause permanent lung damage after long-term exposure
-Damages plants and ecosystems
Health Problems:
-Ozone can irritate lung airways and cause inflammation much like a sunburn. Other symptoms include wheezing, coughing, pain when taking a deep breath, and breathing difficulties during exercise or outdoor activities. People with respiratory problems are most vulnerable, but even healthy people that are active outdoors can be affected when ozone levels are high.
-Repeated exposure to ozone pollution for several months may cause permanent lung damage. Anyone who spends time outdoors in the summer is at risk, particularly children and other people who are active outdoors..
-Even at very low levels, ground-level ozone triggers a variety of health problems including aggravated asthma, reduced lung capacity, and increased susceptibility to respiratory illnesses like pneumonia and bronchitis.
Plant and Ecosystem Damage
-Ground-level ozone interferes with the ability of plants to produce and store food, which makes them more susceptible to disease, insects, other pollutants, and harsh weather.
-Ozone damages the leaves of trees and other plants, ruining the appearance of cities, national parks, and recreation areas.
-Ozone reduces crop and forest yields and increases plant vulnerability to disease, pests, and harsh weather.
2. Particulate Matter- the term for particles found in the air, including dust, dirt, soot, smoke, and liquid droplets. Some particles are directly emitted into the air. They come from a variety of sources such as cars, trucks, buses, factories, construction sites, tilled fields, unpaved roads, stone crushing, and burning of wood.
3. Carbon Monoxide-
4. Nitrogen Dioxide-
5. Sulfur Dioxide-
6. Lead-
