A study on indoor and outdoor air particulate matter (PM10) concentration and composition in the classroom / Mohd Farid Masdar

A study was conducted at inside and outside classroom at room B404 at Faculty of Applied Science, Universiti Teknologi Mara (UiTM) for indoor and outdoor air Quality. The indicator of air pollutants were particulate matter (PMio). The instruments used for this study are Air mini Volume Sampler and ICP-OES. The monitoring was conducted during semester on for weekdays and weekends. From the study carried out had shown that the level of air pollutant (PMio) at outside classroom at weekdays was generally high, exceeding the Malaysian Ambient Air Guidelines, (1995). From the measurement, concentration of PMio exceeds the limit because of the vehicles and the construction activities. The highest value of PMio measurement reaches almost 157ug/m3 , which is obtained at outside classroom at weekdays. Four elements were determined that are, lead, zinc, copper and calcium. The elements had highest concentration was calcium and the element had lowest concentration was lead at all 4 separate days.
