Question

At any particular place the relation between the suspended particulate matter (SPM) and respirable particulate matter (RPM) is

• A. SPM>RPM
• B. SPM<RPM
• C. SPM = RPM
• D. No relation between SPM and RPM

Hint:

Monitoring SPM and RPM in mining environments is crucial for assessing air quality and protecting workers from respiratory health risks.

Answer 1

The Correct Option is A

Suspended Particulate Matter (SPM) refers to all airborne particles, including those of various sizes, while Respirable Particulate Matter (RPM) specifically refers to particles small enough (typically less than 10 micrometers) to be inhaled into the lungs. Since RPM is a subset of SPM, the total amount of SPM at any given place will always be greater than or equal to the RPM. In practice, SPM includes larger particles that are not respirable, so SPM>RPM. There is a clear relationship between the two, as RPM is part of SPM.
Thus, the correct answer is SPM>RPM.
