Fine airborne particles called ?PM10 ? are considered the most important outdoor air pollutant in British Columbia today. They are a concern because they can be inhaled into the lungs, where they can remain for weeks to months before being removed by the body?s natural defense mechanisms. Medical studies indicate that PM10 is associated with a variety of health effects, ranging in severity from increased coughing and school absenteeism, to a significant rise in the number of premature deaths. PM10 consists of a mixture of particles of varied size, composition and origin. These particles originate from both natural and human-related activities. In addition, they are emitted directly to the atmosphere (primary particles) and produced in the atmosphere from chemical and physical processes involving various gases (secondaryparticles). BC Environment has monitored PM10 levels at close to 100 sites in British Columbia since the mid-1980?s. The current network consists of a mix of over 40 manual samplers and 20 con
