PM10

PARTICULATE MATTER 10-PM

WHAT IS PM10?

PM10 is suspended particulate matter in the air that when viewed under a microscope measures less than 10 microns in diameter. Particulate matter is formed by many processes including wind, the pollination of plants, and forest fires. The primary man-made sources of PM10 include the combustion of solid fuels such as wood and coal, agricultural activities such as fertilization and grain storage, and construction activities. PM10 was recognized as a criteria pollutant in 1987 (revised from the original total suspended particulate matter pollutant included in The Clean Air Act of 1970).

EFFECTS OF PM10

Particulate matter can have both health and welfare effects on humans. PM10 can contribute to increased respiratory illnesses such as bronchitis and can exacerbate the effects of other cardiovascular diseases. Visibility and the speed of deterioration of many man made materials can also be effected by particulate matter.

CONTROL EFFORTS

Many steps can be used to control PM10. Often businesses are required to treat gravel parking lots and alleys with chemicals designed to prevent the distribution of fugitive dust into the air. Furthermore control equipment may be required in various industries to impede the release of particulate matter produced as a by-product of their operations.
