| Abstract | Indoor pollutants concentration, including PM2.5, PM10 and TSP were monitored in different locations in the AIT campus, located in the Northern suburb of Bangkok Metropolitan Region. Sampling was conducted at six locations: Environmental Engineering Laboratory (EEM Lab), student villages (SV), Standard dormitory, EEM offices and class room. All samples were collected during dry and rainy seasons 2018. The indoor level of PM2.5, PM10 and TSP were found highest in the accommodation campus, with 45.1 μg/m3,150.7 μg/m3,160.4 μg/m3, respectively. Office 1 had the lowest concentration of all PM2.5, PM10 and TSP. The average concentration of PM2.5 in office 2 was also less than the WHO guideline, but the concentration in the class room and laboratory were more than the WHO guide line. The class room and dormitory standard room had PM10 concentrations more than the WHO guideline. Generally, there is no difference among the ratio between PM10 and TSP in all locations. For the ratio of PM2.5 to TSP, some variations can be observed, ranging from 0.47 in SV to 0.73 in office. The 24- hr concentration monitoring was done in different locations. Higher level of particulate matter concentration was found during cooking in AIT. The survey was conducted at different AIT clusters (staffs, students and family). Cluster sampling was used in the study area in order to select the representative number of people for questionnaire survey and better identify the perception on IAP in the AIT community. The survey was conducted with 166 respondents. Among on campus accommodations about 55 percent of the campus accommodations have kitchen inside the house (attached kitchen), 30 percent of the houses have separated kitchen and 15 percent don’t have kitchen. All the campus accommodations have mechanical ventilation and windows. Among the total classroom selected for the survey, about 63 percent of the classrooms did not have windows. About 97% of students felt some symptoms during class time. Among the total office samples, about 62.5 % of the offices did not have windows. Of all the respondents, thirteen people considered good indoor air quality in the areas. In order to better identify the perception of indoor air quality in the AIT community. PM concentration was measured, and the indoor air quality was evaluated by the questionnaire survey. The indoor level of PM2.5 was found in the campus at 45.1 μg/m3, and 65 percent of respondents in campus experienced with the poor air quality. Fifty- one percent of the students in the classroom answered that they were exposed with poor indoor air quality, and the indoor level of PM2.5 was found in the classroom at 26.7 μg/m3. The indoor high level of PM2.5 was found in the office at 15.3 μg/m3, and 21 percent of respondents in campus reported that AIT had poor air quality. The methodology in this study, including survey questionnaire, monitoring methods and equipment, can be used to apply in Kabul city, Afghanistan to assess the current concentration of indoor air quality in the city. However, the indoor particulate matter concentration in Kabul city were expected to be higher than the concentration in AIT since soil fuel burning was a common practice in Kabul city. |
