EPA and CDC develop online course on Particle Pollution

Particle pollution, also known as particulate matter or PM, is the main component of haze, smoke, and dust. An extensive body of scientific evidence shows exposure to ambient particles can cause adverse cardiovascular effects and premature death and is likely to cause respiratory effects. People with heart or lung diseases, children (less than 18 years old), older adults, people with diabetes, and people of lower socio-economic status (SES) are the most likely to be affected by particle pollution exposure.
