| 中文摘要: |
| 结合2003—2014年南京城区春节除夕前后主要空气污染物监测数据，分析烟花爆竹集中燃放时空气污染指数及PM10、SO2、NO2质量浓度的变化趋势。指出除夕燃放烟花爆竹会引起PM10、SO2、NO2质量浓度上升，在大气扩散条件不佳的情况下影响了环境空气质量。建议在大中城市城区采取适当的禁放措施，并加快研制安全环保型的烟花爆竹替代产品。 |
| 英文摘要: |
| Based on the main pollutants monitoring data in Nanjing city during the Spring Festivals from 2003 to 2014, the variation trend of air pollution index and the concentration of PM10, SO2 and NO2 was analyzed when huge number of firecrackers were set off in short time. The concentration increase was observed as for PM10, SO2 and NO2 during the period of setting off fireworks on the New Year′s Eve, which affects the air quality in case of bad air diffusion condition. It suggests that proper countermeasures such as prohibition to set off fireworks should be taken in big or middle scale cities, and researches on environmental friendly and safety fireworks should be promoted. |
