N2 - The samples of PM2.5 with 8 times periods were collected using Automated Cartridge Collection Unit (ACCU) of Rupprecht& Patashnick (R&P)Corporation, and monitored by R&P1400a instrument of TEOM series online during 2011 Spring Festival in Xi'an city. The organic carbon (OC), elemental carbon (EC), water-soluble organic carbon (WSOC) and water-insoluble organic carbon (WIOC) contents of 3 h integrated PM2.5 were analyzed to evaluate the influence of firework display on the carbonaceous components in urban air. The mass concentration of PM2.5 was found increased significantly from 00: 00 A.M. to 02: 59 A.M. at the Chinese Lunar New Year's Eve than the non-firework periods, reaching 1 514.8 μg·m-3 at 01: 00 A.M. The mass concentrations of OC, EC, WSOC, and WIOC during the same time period were 123.3 μg·m-3, 18.6 μg·m-3, 66.7 μg·m-3, and 56.6 μg·m-3, about 1.7, 1.2, 1.4, and 2.2 times higher than the average in normal days, respectively. Correlation analysis among WSOC, OC, and EC contents in PM2.5 showed that firework emission was an obvious source of carbonaceous aerosol in the Spring Festival vacation. However, it only contributes to 9.4% for aerosol in fireworks emission.
