The aims of the study was to set up the Canister-Automated gas chromatography/mass spectrometry (GC/MS) for monitoring volatile organic compounds toxic chemicals in environmental air of Hsin-chu Science-based Industrial Park.and assess the accuracy, practicability, and widespread of this method.This monitoring system is to refer the EPA-TO serious methods for basis and was to analyze simultaneously and precisely widespread species (C2-C10 HCs, CFCs, included 56 polar and non-polar compounds shown in method TO-15). The system has been practically applied to demonstrate the spatial distribution of pollutant concentrations in Hsin-chu Science-based Industrial Park,and acquired data with the combination of local meteorological information were discussed to notice the sources of pollutant emission and further to establish fingerprints of pollutant sources, assessments of the quality of air, and applications of exclusive indicator.
