The effects of combustion of the fire crackers on the air quality in eastern Central India were studied for the first time during Diwali festival. This case study analyzes the size distribution and temporal variation of aerosols collected in the rural area of eastern Central India during pre-diwali, Diwali and post-diwali period for the year of 2011. Fifteen aerosol samples were collected during the special case study of Diwali period using Andersen sampler. The mean concentrations of PM10 (respirable particulate matter) were found to be 212.8 ± 4.2, 555.5 ± 20.2 and 284.4 ± 5.8 during pre-diwali, Diwali and post-diwali period, respectively. During Diwali festival PM10 concentration was about 2.6 and 1.9 times higher than pre-diwali and post-diwali period, respectively. PM2.5 (fine) and PM1 (submicron) concentrations during Diwali festival were more than 2 times higher than pre-diwali and post-diwali.
首次在排灯节期间研究了印度中部东部地区鞭炮燃烧对空气质量的影响。本案例研究分析了 2011 年排灯节前、排灯节期间和排灯节后印度中部东部农村地区采集的气溶胶的粒径分布和时间变化。在排灯节的特别案例研究中，使用 Andersen 采样器采集了 15 个气溶胶样本。结果表明，在排灯节前、排灯节期间和排灯节后，PM10（可吸入颗粒物）的平均浓度分别为 212.8±4.2、555.5±20.2 和 284.4±5.8μg/m3。在排灯节期间，PM10 浓度分别比排灯节前和排灯节后高约 2.6 和 1.9 倍。排灯节期间的 PM2.5（细颗粒物）和 PM1（亚微米颗粒物）浓度比排灯节前和排灯节后分别高出 2 倍以上。
