Fine Particulate Matter (PM2.5) Information
Industrial and residential combustion and vehicle exhausts emit fine particles into the air. These activities include burning oil, coal, wood, or residential waste. Fine particles also form in the atmosphere when chemical reactions transform gases such as sulfur dioxide, nitrogen oxides, and volatile organic compounds, emitted by combustion activities in the air. Fine particles can effect the health of everyone but primarily affect children, elderly and individuals with asthma and cardiopulmonary disease.
