For information on Particulate Matter click on links below:
Particulate Matter- (PM-10) is the general term used for
the mixture of solid particles and liquid droplets found in the
air. Some particles are large or dark enough to be seen as soot
or smoke. Others are so small they can be detected only by an electron
microscope. Coarse particles are generally emitted from sources
such as, vehicles traveling on unpaved roads, materials handling,
and crushing and grinding operations, as well as windblown dust.
Inhalable PM includes both fine and coarse materials. Exposure to
coarse particles is primarily associated with the aggravation of
the respiratory conditions, such as asthma. Fine particles are most
closely associated with health effects as increased hospital admissions
and emergency visits for heart and lung disease, increased respiratory
symptoms and disease, decreased lung function, and even premature
death.
