“…To exclude the effects caused by meteorological conditions, CO [ 41 , 50 , 51 ] was selected as a reference indicator to compare and analyze the contribution of fireworks burning to PM 2.5 before and after the POFB policy and RHFB policy, and calculated as follows:

The findings underscored the necessity of implementing the POFB policy during the Spring Festival [ 41 ]. Yao et al analyzed the changes in air quality before and after fireworks burning by measuring the concentrations of gaseous pollutants in Shanghai from 2013 to 2017 and found that PM 2.5 concentrations showed a decreasing trend after the implementation of the POFB policy [ 42 ].…”

Fireworks burning significantly degrades air quality over a short duration. The prohibition of fireworks burning (POFB) policy of 2016 and the restricted-hours fireworks burning (RHFB) policy of 2023 in Zhengzhou City provide an ideal opportunity to investigate the effects of such policies and of fireworks burning on air quality during the Spring Festival period. Based on air quality ground-based monitoring data and meteorological data for Zhengzhou City, the article analyzes the impact of the POFB policy and the RHFB policy on air quality. The results show that: (1) The ban on fireworks burning significantly affects Spring Festival air quality, with a decrease of 16.0% in the Air Quality Index (AQI) value in 2016 compared to 2015 and a 74.9% increase in 2023 compared to 2022. (2) From 2016 to 2022, the Spring Festival period witnessed a substantial decrease in average concentration of main pollutants, along with a delayed occurrence of peak concentrations, indicating a noticeable “peak-shaving” effect. However, in 2023, there was an increase in pollutant concentrations, volatility, and a significant surge in hourly concentration. (3) The POFB policy and RHFB policy notably impacted PM2.5 and PM10, with a decrease of 16.1% and 23.6% in PM2.5 and PM10 concentrations, respectively, in 2016 compared to 2015, but an increase of 74.5% and 79.2%, respectively, in 2023 compared to 2022. (4) The contribution of fireworks burning to PM2.5 concentrations significantly decreased during the fireworks burning period (FBP) in 2016 after the POFB policy and increased significantly in 2023 during FBP after the implementation of the RHFB policy. Unfavorable meteorological conditions will undoubtedly exacerbate air quality pollution caused by fireworks burning.

“…As the scope continued to expand, nearly 160 prefecture-level cities had implemented the fireworks ban by the end of 2018 [17,18]. Several studies have examined the positive impact of fireworks bans on controlling air pollution [19][20][21][22][23]. Before the arrival of the 2023 CNY, the debate surrounding whether fireworks burning should be reinstated has once again become a topic of public concern, with an intensity exceeding previous years.…”

During the 2023 Chinese New Year (CNY), many city governments relaxed restrictions on residents setting off fireworks. Fireworks contain large amounts of sulfur powder, which releases the toxic air pollutant sulfur dioxide (SO2) when combusted rapidly. In this study, we employed a four-dimensional variational (4DVar) assimilation system to examine variations in SO2 emissions in China by assimilating hourly ground-based observation data. Two sets of experiments were conducted during the CNY in 2022 and 2023 to quantify the variations in SO2 emissions. On CNY's Eve in 2022, nationwide SO2 emissions increased by 4.701 Gg compared to the preceding day. During the CNY in 2023, following the relaxation of the fireworks ban, there was a significant upsurge of 8.22 Gg in SO2 emissions on CNY's Eve compared to the previous day. This increase included a rise of 2.037 Gg in the Energy Golden Triangle region, 1.709 Gg in the North China Plain and 0.945 Gg in northeastern China. After reaching the peak on CNY's Eve, the overall national SO2 emissions during the 2023 CNY showed a rapid decline in the following two days. However, the emission levels remained elevated compared to the pre-CNY period, indicating the lingering effects of fireworks burning. Compared to the forecasts using the prior emissions, the optimized emissions markedly improved the model forecasts of SO2 during the 2023 CNY period, evidenced by an increase in the correlation coefficient (R) from 0.12 to 0.63 and a reduction in the root-mean-square error (RMSE) by 49.9%, demonstrating the effectiveness of the optimized emissions. These findings will be useful for local governments in formulating strategies for fireworks burning during the CNY period.
