Did You Know?
PM2.5 is a major component of wood smoke, vehicle exhaust, wildfires, and tobacco and cannabis smoke.
Fine Particulate Matter is defined as particles smaller than 2.5 µm (microns) in diameter and can consist of solids, liquids, and gasses.
These tiny particles are not captured by the filtering hairs in our nostrils and can be inhaled deep into the lungs. Inside the lungs, the particles can get stuck in the sensitive tissues, and, similar to a splinter, can cause inflammation.
Because of the serious health effects associated with exposure to fine particulate matter, PM2.5 is a component of the Air Quality Health Index (AQHI).
There is no “safe” level of PM2.5 in the air. Even low concentrations can:
- Increase respiratory symptoms
- Increase risk of developing asthma
- Increase risk of cardiovascular disease
In New Brunswick, home heating with wood is the number 1 source of PM2.5 in the wintertime.
You can reduce the PM2.5 you contribute to our air by:
- Avoiding burning wood
- Opting for healthy transportation as much as possible
- Choosing electric appliances and yard equipment
