%X Nine PAHs were surveyed in communication air of Hangzhou. The results indicated that the PAHs pollution is very serious and the total sum of 9 PAHs, on the average are 3.39-13.82 micrograms/m3. The PAHs signatures for all streets are similar to each other. Multivariate statistical techniques were used to investigate source apportionment for PAHs. A factor analysis/multiple regression model was successfully applied to the study. The most important three PAHs sources in communication air are diesel emission, gasoline engine emission, coal-burning accounting for 61.1 +/- 6.4%, 19.9 +/- 8.3%, 10.8 +/- 10.8% of total PAHs, respectively. The relationship for three source tracers and total PAHs is: PAHs] = 1.471 (+/- 0.155) Phen] + 2.538 (+/- 2.522) 1 - Mepy] + 2.254 (+/- 0.943) Chry] + 1.022 (+/- 1.767).
