Health and Environmental Effects of Particulate Matter (PM)
Health Effects
The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter pose the greatest problems, because they can get deep into your lungs, and some may even get into your bloodstream.
Exposure to such particles can affect both your lungs and your heart. Numerous scientific studies have linked particle pollution exposure to a variety of problems, including:
premature death in people with heart or lung disease
nonfatal heart attacks
irregular heartbeat
aggravated asthma
decreased lung function
increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing.
People with heart or lung diseases, children, and older adults are the most likely to be affected by particle pollution exposure.
AirNow can help you monitor air quality near you, and protect yourself and your family from elevated PM levels.
Environmental Effects
Visibility impairment
Fine particles (PM2.5) are the main cause of reduced visibility (haze) in parts of the United States, including many of our treasured national parks and wilderness areas. Learn more about visibility and haze
Environmental damage
Particles can be carried over long distances by wind and then settle on ground or water. Depending on their chemical composition, the effects of this settling may include:
making lakes and streams acidic
changing the nutrient balance in coastal waters and large river basins
depleting the nutrients in soil
damaging sensitive forests and farm crops
affecting the diversity of ecosystems
contributing to acid rain effects.
Materials damage
PM can stain and damage stone and other materials, including culturally important objects such as statues and monuments. Some of these effects are related to acid rain effects on materials.
