A Study on the indoor air quality (IAQ) at primary school in Industrial Area: A case study to Sekolah Kebangsaan Pasir Gudang 3(SKPG3)

Abstract

Abstract Existing research has shown that numerous air contaminants are present in classrooms, sometimes in high concentrations, which may have an impact on children’s health and academic performance. In order to create a safe, healthy, productive, and comfortable atmosphere for students, instructors, and other school personnel, schools must have good indoor air quality. This study has assessed the current IAQ’s level at selected school in one of the industrial areas in Johor Bahru, which is Pasir Gudang. To measure the quality of the indoor air parameters, three chemical substances which are Formaldehyde (HCHO), Total Volatile Organic Compound (TVOC) and Particulate Matter (PM) in the classroom were assessed. Besides that, this study also analyzed the temperature and relative humidity of the classroom surrounding. Furthermore, the students’ insight on the impact of IAQ parameters towards their class performances were also explored using questionnaire survey. It was found that physical parameters of the classroom were in good state, but the relative humidity percentage range was too high. Meanwhile, on the chemical contaminants, the measurement shows that the concentration of PM, HCHO and TVOC for the classroom are still in the permissible exposure range. In the end, some suggestions have been made to provide good indoor quality in the classroom by emphasizing proper design, construction, and ongoing maintenance procedures.
