Airborne Particulate Monitoring

摘要

Monitoring particle pollution in air can be a challenging task. Unlike pollutant gases which are well defined compounds, particulate pollution is a mixture of compounds which can exist in various physical states. Current air quality legislation requires the measurement of all particulate matter (PM) in terms of mass per cubic meter of air. However many specialists believe that the number of particles and their chemical composition are just as important as mass in terms of health effects.
