Abstract

Diwali is an important festival of India and a lot of firecrackers bursting take place in every part of the country during festive occasions. Short term effect of firecrackers on ambient air quality was assessed by monitoring suspended particulate matter (SPM) and heavy metal analysis (Fe, Zn, Pb, Mn and Ni) during Diwali festival at an urban-industrial city Raipur, India from 3rd November to 11th November 2018. The daily average SPM concentrations were found about two times higher on 7th November (Diwali-425.64 µg/m3) and 8th November (next day of Diwali- 417.92 µg/m3) as compared to 3rd November (pre Diwali day- 247.56 µg/m3). Heavy metal analysis (Fe, Zn, Pb, Mn and Ni) was carried out using atomic absorption spectroscopy (AAS) and found the same concentration trend in the order of Fe>Zn>Pb>Mn>Ni during day and night time. Significant increment in SPM and heavy metal concentrations has been observed post-Diwali. Back trajectory analysis revealed that trajectories at surface level (50 and 1000 m a.g.l) originated from local sources, depicting local anthropogenic activities like burning of firecrackers and industrial activities as major pollution source. Wind rose diagram depicts higher SPM concentration, when the wind was northeasterly. The present study reveals that pollution levels were considerably increased during Diwali and firecrackers bursting played a major role by contributing to air pollution.

排灯节期间的悬浮颗粒物和重金属分析评估

排灯节是印度的一个重要节日，在节日期间，印度各地都会燃放大量鞭炮。2018年11月3日至11月11日，在印度城市工业城市赖布尔举行的排灯节期间，通过监测悬浮颗粒物（SPM）和重金属分析（Fe、Zn、Pb、Mn和Ni），评估了鞭炮对环境空气质量的短期影响。11月7日，SPM的日均浓度高出约两倍（排灯节425.64 µg/m3）和11月8日（排灯节的第二天-417.92 µg/m3）与11月3日（排灯节前-247.56 µg/m3）。用原子吸收光谱法对重金属（Fe、Zn、Pb、Mn和Ni）进行了分析，发现在白天和晚上的浓度趋势相同，依次为Fe>Zn>Pb>Mn>Ni。排灯节后，SPM和重金属浓度显著增加。背面轨迹分析显示，地表（50和1000）的轨迹 m a.g.l）来源于当地，将当地的人为活动（如燃放鞭炮和工业活动）描述为主要污染源。风玫瑰图描绘了东北风时SPM浓度较高的情况。目前的研究表明，排灯节期间污染水平大幅上升，鞭炮爆裂是造成空气污染的主要原因。
