Particulate Matter (PM) can be defined as a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids, organic chemicals, metals, and soil or dust particles. The Clean Air Act, written by the United States government, requires the Environmental Protection Agency (EPA), to set National Ambient Air Quality Standards (NAAQS) for six criteria pollutants, particle pollution, or PM, is one of these. Standards are in place to set limits to protect public health, including the health of “sensitive” populations such as asthmatics, children, and the elderly. In addition, secondary standards were also created that focus on setting limits to protect public welfare, including protection against visibility impairment, damage to animals, crops, vegetation, and building.
If you are concerned about the PM levels in your indoor environment, contact Environmental Analytics to perform real-time, on-site investigations that will help determine whether your environment meets compliance to EPA’s NAAQS for particle pollution.
