Hazardous Air

HAZARDOUS AIR PM2.5: Particles less than 2.5 micrometers in diameter are called "fine" particles. These particles, approximately 1/30 the average width of a human hair, can lodge deep in the lungs. Sources of fine particles include all types of combustion, including power plants, motor vehicles and residential wood burning. PM2.5 is easily inhalable and can penetrate deep into the lungs. PM2.5 allows many chemicals harmful to human health to be carried to the internal organs, causing a wide range of illnesses, including cancer (especially lung cancer), stroke and damage to unborn children. They have a strong association with most types of respiratory illnesses, heart disease and even deaths.
