“…Meanwhile, fireworks burning becomes an important pollution source during the Spring Festival. There have been some studies on the characteristics of fireworks pollution, including its impacts on fine and coarse particles (Chang et al, 2011;Huang et al, 2012;Li et al, 2013;Jing et al, 2014;Zhao et al, 2014;Jiang et al, 2015;Lin et al, 2016), source apportionment (Feng et al, 2012;Tian et al, 2014b) and human health risk assessment Shi et al, 2014;Yang et al, 2014).…”

Air pollution especially of PM 2.5 pollution is a serious problem in Beijing. In order to quantify the effect of a festival in which pollution was expected to be reduced, we collected and analyzed PM 2.5 samples in urban Beijing during the 2015 Spring Festival (from February 9 th to March 6 th 2015). We divided the sampling period into three phases: non-haze, haze and firework days. The average concentration of PM 2.5 was highest on firework days at 248.9 µg m -3 , followed by haze days (199.9 µg m -3 ) and non-haze days (90.8 µg m -3 ). The air quality of non-haze days during the holiday was better than that during non-holiday periods. 2-/K + and Cl -/K + effectively distinguished the characteristics of PM 2.5 between firework events and haze days. Ion balance calculations indicated that the acidity of PM 2.5 from firework days was higher than that from haze and non-haze days. A method using enrichment factors (EF) found that crustal elements (EF < 10 on all three types of days) included Ca, Al, Fe, Na, Co, Ni, P, Ti, and V; firework elements (EF > 10 on firework days, significantly higher than haze days) were made up of Ba, Cr, Cu, Mg, Pb, S, Si, and Zn; common anthropogenic pollution elements (EF > 10 in all three types of days) were As, Cd, Cu, Pb, S, Sb, Zn. Differences in chemical characteristics indicated that holidays such as the Spring Festival can affect air pollution patterns in two ways: a decrease in the population and vehicles but an increase in activities such as firework displays.

“…Those values were in accordance with the range 0.20 to 0.50, where in previous studies it was shown that, for these values, the PAHs originate from petroleum sources such as liquid fossil fuel, vehicle and oil combustion [53], and those between 0.35 and 0.70 imply diesel emissions [54]. The BaA/(BaA + Chry) ratios obtained, 0.40-0.52 (0.47 ± 0.04) for Centro and 0.35-0.56 (0.44 ± 0.05) for Miravalle, were similar to 0.38-0.64 and 0.22-0.55, which have been associated with diesel and gasoline emissions, respectively [55,56]. The values of Flt/(Flt + Pyr) were 0.22-0.50 (0.45 ± 0.07) for Centro and 0.16-0.56 (0.45 ± 0.08) for Miravalle.…”

. Spatial variations were found during the dry-warm season, which were attributed mainly to differing intensities of local traffic and less dispersion of air pollutants in Miravalle. Seasonal variations were associated with increases in rainfall (June-September) and differences in temperature (January-May and October-January). The benzo(a)pyrene-equivalent (BaPE) and BaP results suggest that exposure to PM 2.5 -containing carcinogenic PAHs (C-PAHs) in Miravalle during the warm-dry and cold-dry seasons can be seen as representing a serious risk to human health. The contributions from potential sources to PAHs in PM 2.5 were evaluated by the diagnostic ratios between PAHs and principal component analysis (PCA). In the whole sampling period, vehicular emission activity, probably related to light and heavy traffic, was found to be the predominant contributor to PM 2.5 -bound PAHs.

“…. S6), likely due to the intensive firecrackers and fireworks displaying for celebrating the two festivals (Jing et al, 2014;Shi et al, 2014;Zhao et al, 2014). The concentrations of EC and OC showed variations up to one order of magnitude (Fig.…”

“…The Chinese Spring Festival (Chinese Lunar New Year; 1st January of Chinese Lunar Calendar) and the succeeding Lantern Festival (15th January of Chinese Lunar Calendar) are important traditional festivals for China and other Eastern Asian countries (Feng et al, 2012;Shi et al, 2014;Tian et al, 2014). All kinds of human activities such as firework displaying, large-scale population migrating from urban to rural areas, etc., are carried out before and after the two Festivals.…”

“…The atmospheric conditions and the source emission patterns during the CSFP (approximately one month) are significantly distinct from usual periods . Thus, there have been a great deal of studies on the characterization of particulate pollution, impacts on air quality of firework-burning, variation and toxicity assessment of particle-associated PAHs and the characteristics of carbonaceous aerosol, etc., during the CSFP (Jing et al, 2014;Jiang et al, 2015;Kong et al, 2015a;Kong et al, 2015b;Liu et al, 2014;Shi et al, 2014;Tian et al, 2014;Zhao et al, 2014). Moreover, during the CSFP, the firecrackers and fireworks displaying is one of the most typical activities, which can release a number of carbonaceous aerosols (OC and EC) into atmosphere (Feng et al, 2012;Tsai et al, 2012;Tian et al, 2014;Yang et al, 2014).…”
