Particle pollution comes from
many different type of sources.
The HHTP21 Particulate meter and particle counter is ideal for
monitoring particulate pollution
in department stores, burning
plants, petrochemical facilities,
thermal power plants, restaurants,
hospitals, mining facilities, metal
refineries, commercial and
public buildings. Fine particle
(2.5 micrometers in diameter
and smaller) are found in power
plants, industrial processes,
vehicle tailpipes, wood stoves,
and wildfires. Coarse particles
(between 2.5 and 10 micrometers)
come from crushing and grinding
operations, road dust, and some
agricultural operations. Particle
pollution is linked a number
of health problems, including
coughing, wheezing, reduced lung
function, asthma attacks, heart
attacks and strokes. It also is
linked to early death.
