Abstract：In China, the most intensive burning of firework event occurs in the New Year Festivities, which release the high concentrations of particles, and cause acute short term air pollution. Concentrations and chemical components of PM10 were measured and analyzed in Nanjing, during the Spring Festival on January 19~31, 2012, for assessing the impacts of fireworks on ambient air quality. The PM1.0 concentration increased at the rate of 15.5μg/(m3·h) and the visibility was reduced at the rate of 1.625km/h during the study period. The results of the mass spectra and water-soluble ions spectrum can be described as trimodal distributions during the burning periods and bimodal distributions during non-burning periods. The ions of K+, SO42-, NO3-, Cl- and Mg2+ in PM2.1 and PM1.1 increased by the range of 16%~38% during the burning periods. For aerosol in the range of 0.2~2.0μm, nitrate, zinc, copper and part of K-including particles were mainly originated from firework burning, however, sulfate particles were hardly originated by this process, Pb-including particles were from industry emission.
