![]() ![]() CDC - Air Quality - Particle Pollution. Particle pollution . These particles may include: Dust. Dirt. Soot. Smoke. Drops of liquid. Some particles are big enough (or appear dark enough) to see . Others are so small that you can't see them in the air.
![]() Where does particle pollution come from? Particle pollution can come from two different kinds of sources . Primary sources cause particle pollution on their own. For example, wood stoves and forest fires are primary sources. Secondary sources let off gases that can form particles. Background: Outdoor fine particulate matter (. Research; The relation between. The relation between past exposure to fine particulate air pollution and prevalent anxiety: observational cohort study. Particulate Matter Air Pollution and Cardiovascular Disease An Update to the Scientific Statement From the American Heart Association. Sources of atmospheric particulate matter. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of. Particulate matter air pollution exposure: role in the development and exacerbation of chronic obstructive pulmonary disease. ![]() Power plants and coal fires are examples of secondary sources. Some other common sources of particle pollution can be either primary or secondary . Coarse (bigger) particles, called PM1. Dust from roads, farms, dry riverbeds, construction sites, and mines are types of PM1. Fine (smaller) particles, called PM2. People most likely to experience health effects caused by particle pollution include: People with heart or lung diseases (for example, asthma)Older adults. Babies and children. If you have asthma, particle pollution can make your symptoms worse. Carefully follow your asthma management plan on days when pollution levels are high. Particle pollution has also been linked to: Eye irritation. Lung and throat irritation. Trouble breathing. Lung cancer. Problems with babies at birth (for example, low birth weight)Heart Disease.

Protect Yourself and Your Family. The good news is there's a lot you can do to protect yourself and your family from the health effects caused by particle pollution. Start by learning about the Air Quality Index from the U. S. Environmental Protection Agency (EPA). Air Quality Index (AQI)The EPA Air Quality Index (AQI) tells you when air pollution is likely to reach levels that could be harmful. You can use the AQI as a tool to help you avoid particle pollution. Local TV stations, radio programs, and newspapers report the AQI. Try checking it when you're planning your daily activities. Take Action. When particle pollution levels are high, take steps to limit the amount of air you breathe in while you're outside. For example: Think about spending more time indoors, where particle pollution levels are usually lower. Choose easier outdoor activities (like walking instead of running) so you don't breathe as hard. Avoid busy roads and highways where PM is usually worse because of emissions from cars and trucks.
