Abstract: This study consists of a comparison of the concentration of particulate matter in indoor air in the laboratories of a technical institute. For this, sampling is done with a portable indoor air sampler from July to October 2021. The total of 228 samples were collected for each particulate matter size i.e., PM2.5 and PM10 in a total of five laboratories. In descriptive statistics, the highest level of concentration of PM was found in the chemical lab and the lowest value was interpreted in the research lab. Further, the comparison study states the means concentration level of both Particulate Matter of sizes <2.5 µm and <10 µm is higher than the prescribed value set by the WHO in all the monitored labs. The average concentration of both Particulate Matter was found higher than the prescribed limit set by WHO. Finally, it can be concluded that poor ventilation, presence of furniture, paints, oils, and electronics, etc., along with the additional influence of the outdoor air pollutants, location of laboratories, and outdoor construction activities, etc. are some of the prime reasons for the high concentration of indoor air particulate matter.
