description	This study aimed to determine the composition, source apportionment and health riskassessment (HRA) of indoor particulate matter (PM2.5) in selected Malaysia traininginstitutes. PM2.5 samples were collected from lecture halls, laboratories and lecturer offices inInstitut Latihan Kementerian Kesihatan Malaysia Sungai Buloh (SB) and Institut Latihan KementerianKesihatan Malaysia Sultan Azlan Shah (SAS). Sampling were conducted over a period of eighthours sampling for five consecutive days with a total number of 30 samples. The samples werecollected on 47 mm micro fiber glass filter paper (0.2 m pore size, Whatman) using low volumeair sampler (LVS) at 5 L min? flow rate. The composition of PM2.5 for water-solubleionic species (WSIS) and trace metals were determined using ion chromatography (IC) and inductively coupled plasma-mass spectrometry (ICP-MS), respectively. Sourceapportionment of PM2.5 was determined using the combination of Principal Component Analysisand Multiple Linear Regression (PCA-MLR) receptor model. HRA was conducted to evaluate thepotential health hazard to adolescent and adult groups in the institutes. The result showed thatthe mean of PM2.5 at SB (51.39 29.95 g m?) was higher than SAS (45.83 20.47 g m?). However,most of WSIS and trace metals were found higher at SAS compared to SB. PCA-MLR results identifiedfour factors, where the main sources of PM2.5 in SB and SAS were biomass burning (48%) andbuilding material / crustal origin (81%), respectively. The adult group has higher hazard index(HI) and incremental lifetime carcinogenic risk (ILCR) values than adolescent group for bothinstitutes. In conclusion, these two institutes have moderate level of air quality, but theyhave the potential to develop adverse health effects. As an implication, this study hasprovided a holistic view of indoor air quality, hence the effective control strategies need to beimplemented to enhance indoor air quality for the comfort ofall building occupants.
