Particle Pollution

Particle pollution (also called particulate matter or PM) is simply solid particles or liquid droplets suspended in the air. Exposure to these suspended particles and droplets can cause serious health problems in humans, especially those with respiratory conditions such as asthma and cardiac disease. The Air Management Program monitors particle pollution around the state and issues advisories when levels become potentially harmful.

To reduce particle pollution, the state and federal regulations target Nitrogen Oxides (NOx) and Sulfur Dioxide (SO2) emissions from power plants and industrial combustion sources. Additionally, mobile source control programs such low-emission vehicles and cleaner gasoline help reduce Volatile Organic Compounds (VOC) and NOx emissions from mobile sources.
