Total Suspended Particulate (TSP)
Definition - What does Total Suspended Particulate (TSP) mean?
Total suspended particulate (TSP) refers to the totality of small solid matter released, documented and/or otherwise observed in the atmosphere. Total suspended particulates are considered to be a primary contributor to air pollution, smog formation and environmental contamination. Corrosion is often a source of certain particulate contributions to TSP.
Corrosionpedia explains Total Suspended Particulate (TSP)
When metals become severely corroded, rust and other particles are formed and displaced from the metal's surface. These dust-like substances contribute to particle emissions in the surrounding atmosphere. As such, corrosion may be a contributing factor to air pollution and a component of the total suspended particulates (TSP) observed and recorded.
Particulate pollution and TSP consist of two main particle sizes: PM10 and PM2.5. PM10 particles have diameters that are generally 10 micrometers and smaller, while PM2.5 particles are fine particles with diameters 2.5 micrometers and smaller.
