What is SPM? What are the air quality standard of PM10 and PM2.5 . A glass fiber filter paper is found to have an initial weight of 8.023 grams. After 24 hours of sapling, using high volume air sampler, the final paper weighed 8.162 grams and the air flow at the start and end of the experiment is 1.4 m3/min and 0.6 m3/min. calculate the concentration of suspended
particulate matter.
