| Popis: | Indoor air quality (IAQ) consolidates various detrimental health consequences include respiratory problems and premature deaths. Debased IAQ inside educational structures may influence students' strength, which can affect their concentration and efficiency. In this study, we measured Size segregated Particulate Matter (PM10, PM2.5, PM1) and CO2 concentration in the four major student occupants area of IIT(ISM) Dhanbad like the Central Library, Main Canteen, Health Centre, and Department of ESE. All the readings were taken during their working hours and found that the canteen area has the highest PM level (PM10: 138 ± 34.19 μg/m3, PM2.5: 87 ± 26.45 μg/m3, PM1: 58 ± 20.63 μg/m3) with lower CO2 concentration (455.56 ± 94.71 ppm). Fine particles (PM2.5) exceed the value of the NAAQS standards at half of the locations, and all locations for the WHO guidelines. Fine particles (PM2.5 & PM1) are mainly caused by the cooking activities in the attached kitchen in the main canteen. PM level in the library is beneath WHO standards because of their closed structure and less outdoor interaction, and thus it gives higher CO2 values (968.76 ± 267.24 ppm). Results shown in the current investigation portray the alarming micro-environmental conditions in the monitored zone. |
