摘 要：In the study, a new method based on the second-order calibration of three-way fingerprints of PAHs（SCTFP） was developed for the source apportionment of urban PM10 for the first time. First, simulated three-way data arrays of GC-MS were used to verify the feasibility of SCTFP. Then, PM10 and pollution source samples were collected during July and August, 2018 in Loudi City, China. After resolving the problems of GC-MS including baseline drift, retention-time shift and unexpected peaks overlapping, chromatographic and mass spectral profiles and concentrations of PAHs were accurately obtained by the second-order calibration of GC-MS data of samples. Last, a contribution matrix of the source to the receptor was estimated according to the obtained concentrations of PAHs. The proposed method was employed to apportion the source contributions to PM10 at five locations and reasonable results were obtained, thus presenting a promising tool for source apportionment of complex ambient particulate matter.
