What Are the Common Pollutants Regulated by Air Quality Standards?
Several key pollutants are commonly regulated by air quality standards: - Particulate Matter (PM10 and PM2.5): These tiny particles can penetrate deep into the lungs and even enter the bloodstream, causing serious health issues. - Nitrogen Dioxide (NO2): This gas can irritate the airways and exacerbate respiratory diseases. - Sulfur Dioxide (SO2): High levels can lead to respiratory problems and aggravate existing heart disease. - Ozone (O3): Ground-level ozone can cause lung inflammation and decrease lung function. - Carbon Monoxide (CO): This colorless, odorless gas can interfere with the oxygen-carrying capacity of blood. - Lead (Pb): Exposure to lead can affect almost every organ and system in the body, particularly the nervous system.
