A., & Yoneda, M. (2017). Characterization and source profiling of volatile organic compounds in indoor air of private residences in Selangor State, Malaysia. Science of the total environment, 586, 1279-1286.https://repoemc.ukm.my/handle/123456789/555Volatile Organic Compounds (VOCs) in indoor air were investigated at 39 private residences in Selangor State, Malaysia to characterize the indoor air quality and to identify pollution sources. Twenty-two VOCs including isomers (14 aldehydes, 5 aromatic hydrocarbons, acetone, trichloroethylene and tetrachloroethylene) were collected by 2 passive samplers for 24 h and quantitated using high performance liquid chromatography and gas chromatography mass spectrometry. Source profiling based on benzene/toluene ratio as well as statistical analysis (cluster analysis, bivariate correlation analysis and principal component analysis) was performed to identify pollution sources of the detected VOCs.enVolatile organic compoundsIndoor airHPLCGC-MSSource profilingCharacterizationJournal
