Safeopedia Explains Milligram Per Cubic Meter
Milligram per cubic meter is commonly used by the industrial hygienists in measuring air pollution. Worker’s exposure to particulates or dusts is usually quantified in mg/m3. This is a measurement of a certain amount of particulates or dusts spread evenly throughout a cubic meter of air at ambient temperature. Occupational health & Safety Administration (OSHA) has established a permissible exposure limit (PEL) of various air pollutants e.g. Cyclohexanol 200 mg/m3 or Phenol 19 mg/m3.
