Particulate matter two-point-five (PM2.5) is a tiny suspended
particle of air pollution that can penetrate deeply into our lungs
and potentially enter the bloodstream. The 2.5 unit means that
the particles are smaller than 2.5 micrometers (a micrometer is
one millionth of a meter). In Cache Valley and along the Wasatch
Front, these tiny particles form and accumulate to unhealthy
levels when air is trapped in the bottom of the valley during
cold winter days.
