Chlorinated and nonchlorinated-volatile organic compounds (VOCs) in drinking water of peninsular Malaysia

A survey undertaken in Peninsular Malaysia has shown that volatile organic compounds (VOCs), both chlorinated and non-chlorinated, are present in selected drinking water samples. In this study, analyses of VOCs were performed by means of solid phase microextraction (SPME) with a 100 μm polydimethyls...
