The aim of this study is to evaluate the pollution caused by fireworks on the day of what is known as Diwali festival which is celebrated every year in October–November. The increase in particle pollutants such as the particulate matter 2.5 (PM_2.5) over a time period around the festival days is noted for a year of 2017 in the city of Chennai, South India, and this increase in pollutant levels is correlated with the increase in health issues present among public during this festival time. It was observed that PM_2.5 varied from 30.06 ± 1.5 to 146.82 ± 7.3 µg/m³ with an average of 68.18 ± 26.84 µg/m³, and the mean concentration for three consecutive years (2015–2017) was lower than National Ambient Air Quality Standards. All the important pollutants such as sulphur dioxide (SO₂), nitrogen dioxide (NO₂) and PM_2.5 have been measured during pre-Diwali, Diwali day and after Diwali at Choolaimedu (CM) and Chinmayanagar (CN) areas. Due to dense population, these areas are expected to have high levels of firework activity and are typical for the study. The gaseous pollutants SO₂ and NO₂ correlated with wind speed, wind direction, temperature and relative humidity. PM_2.5 had good correlation with SO₂. Eye irritation was found to be the most common health issue, which affected 44.3% of the total surveyed residents during these festival days.

这项研究的目的是在每年10月至11月庆祝的排灯节这一天，评估烟花造成的污染。在印度南部金奈市，节日期间的某个时间段内，颗粒污染物2.5（PM _2.5）等颗粒污染物的增加在2017年被注意到，而污染物水平的增加与该增加相关在节日期间公众中出现的健康问题。观察到PM _2.5从30.06±1.5到146.82±7.3 µg / m ^3变化，平均为68​​.18±26.84 µg / m ³，并且连续三年（2015-2017年）的平均浓度低于国家环境空气质量标准。在排灯节之前，排灯节期间以及排灯节之后，在Choolaimedu（CM）和Chinmayanagar（CN）地区都测量了所有重要的污染物，例如二氧化硫（SO ₂），二氧化氮（NO ₂）和PM _2.5。由于人口稠密，这些地区的烟火活动预计会很高，这是该研究的典型结果。气态污染物SO ₂和NO ₂与风速，风向，温度和相对湿度有关。PM _2.5与SO ₂具有良好的相关性。人们发现，眼睛刺激是最常见的健康问题，在这些节日期间，它影响了全部被调查居民的44.3％。
