Particle pollution (also known as particulate matter (PM)) is composed of solid or liquid particles (small pieces) in the air. These particles may include:
·Drops of liquid
You can see that some particles are big enough (or look dark enough), for example, you can often see smoke in the air. The others are too small for you to see in the air.
Particle pollution can come from two different sources: primary or secondary. The main pollution source itself will cause particle pollution. For example, firewood stoves and forest fires are the main sources.
The secondary source releases gases that can form particles. Power plants and coal fires are examples of secondary energy. Other common sources of particulate pollution may be primary or secondary, such as factories, cars and trucks, and construction sites.
PM2.5 is contained in smoke generated by fire and exhaust gas from power plants, industrial facilities, automobiles and trucks.
Inhalation of particulate pollution is harmful to your health. Coarse (larger) particles, called PM10, can irritate your eyes, nose, and throat. Dust from roads, farms, dry river beds, construction sites and mines is a type of PM10.
Fine particles called PM2.5 are more dangerous because they can go deep into the lungs and even into the blood.

When the level of particle pollution is high, take measures to limit the amount of air you inhale outside. For example:
Think about spending more time indoors, where particle pollution levels are usually lower.
Choose simpler outdoor activities (such as walking rather than running) so you don't have breathing difficulties.
Avoid driving on busy roads and expressways because the emissions from cars and trucks usually increase the concentration of particles.
