SPM (Suspended Particulate Matter) refers to particles suspended in the air, such as dust, dirt, smoke, and aerosols. These particles can come from natural sources such as wind-blown dust, sea spray, and volcanic eruptions, as well as from human activities like burning of fossil fuels, construction, industrial activities, and vehicular emissions. SPM can have many adverse effects on human health, including reduced lung function, asthma, respiratory irritation, and decreased visibility. It can also lead to increased acid rain and the deposition of hazardous metals in the environment. Additionally, SPM can decrease crop yields and reduce the growth of vegetation.
Suspended matter consists of dust, fumes, mist and smoke. The main chemical component of SPM that is of major concern is lead, others being nickel, arsenic, and those present in diesel exhaust. These particles when breathed in, lodge in our lung tissues and cause lung damage and respiratory problems.
Definition: Suspended particulate matter (SPM) are finely divided solids or liquids that may be dispersed through the air from combustion processes, industrial activities or natural sources.
