What is the full form of SPM?

SPM Full Form is Suspended Particulate Matter.
SPM are particulate air pollutants, particularly sourced from vehicle exhaust, ash, soot, atmospheric dust, dust due to wind, sandstorms and dust storms etc. Tiny particles found in liquids and solids are called particulate matter. These particles are too big to dissolve in water. They are the third most important part of aquatic ecosystems, providing structure and function. Each body of water has its own type and amount of particulate matter, influenced by factors like urban development, land use, and the type of rocks in the area. The amount of particulate matter can also change based on the season, weather, water flow, and the use of fertilizers.
