Total Suspended Particulate (TSP) refers to microscopic particles of solid or liquid matter suspended in the air. TSP is measured in micrograms per cubic meter of air (µg/m3) and is determined by a gravimetric method using a sampler with a downward pointing tube and a face velocity of 0.5 m/sec. The annual standard level is defined to one decimal place, such as 15.0 µg/m3. TSP includes all airborne particles and is related to other particulate matter measurements such as PM10 and PM2.5. Sources of TSP can be both natural and anthropogenic, and it is an important component in assessing air quality and environmental health.
