Major Air Pollutants
Air pollution is caused by the release of harmful gases and particles into the air. These pollutants can cause a variety of respiratory diseases, including asthma, bronchitis, and COPD (chronic obstructive pulmonary disease). The major air pollutants that cause respiratory diseases include:
Particulate Matter (PM): Particulate matter, often referred to as PM, is a type of air pollutant that consists of tiny particles suspended in the air. These particles can include dust, soot, smoke, and other pollutants. Long-term exposure to PM can cause a variety of respiratory diseases, including asthma, bronchitis, and COPD.
Nitrogen Dioxide (NO2): Nitrogen dioxide is a pollutant that is produced by burning fossil fuels, such as gasoline and diesel. It can cause a variety of respiratory diseases, including asthma and COPD. Long-term exposure to nitrogen dioxide can also lead to an increased risk of developing lung cancer.
Sulfur Dioxide (SO2): Sulfur dioxide is a pollutant that is produced by burning fossil fuels, such as coal and oil. It can cause inflammation of the airways and can worsen existing respiratory conditions, such as asthma. Long-term exposure to sulfur dioxide can also lead to an increased risk of developing lung cancer.
Volatile Organic Compounds (VOCs): Volatile organic compounds, often referred to as VOCs, are a type of air pollutant that are emitted by a variety of sources, such as paint, cleaners, and solvents. Long-term exposure to VOCs can cause a variety of respiratory diseases, including asthma and COPD.
Ozone (O3): Ozone is a pollutant that is produced by the reaction of sunlight with certain pollutants in the air. It can irritate the airways and can worsen existing respiratory conditions, such as asthma. Long-term exposure to ozone can also lead to an increased risk of developing lung cancer.
