“…Several researchers have examined degradation in air quality due to the Diwali celebration in various regions of India [20,27,[29][30][31], and have also reported an increase in particulate matters and pollutant gases, such as PM2.5, PM10,O3, NO2, SO2, and trace metals during the Diwali celebration.According to Attri et al, burning and huge fireworks displays during Diwali led to the creation of the potent secondary pollutant ozone at ground level [32,33].Research on the ambient air quality in Lucknow during the celebrations of Diwali revealed a range of PM10, SO2, and NOx concentrations [30,34]. When compared to their respective concentrations on pre-Diwali and regular days, the 24-hour average concentrations of NOx, SO2, and PM10 on Diwali day were found to be 6.59 times higher for NOx, 1.95 times higher for SO2, and 2.49 times higher for PM10 [30,34].…”

The current study focuses on the impact of firecrackers emission on particulate matter (PM2.5 and PM10), carbon monoxide (CO), carbon dioxide (CO2), and total volatile organic compounds (TVOC) and the noise was analyzed on pre, during, and post-Diwali 2022 period (5 days) in a residential area of Tamil Nadu state of India. The findings demonstrated that, for 24-hour mean values of PM2.5 and PM10 concentrations over the study period were consistently higher than the NAAQS (National Ambient Air Quality Standard) permitted limit. On the day of Diwali, the mean CO concentration reaches 2.5 mg/m3, exceeding the NAAQSrecommended allowable limit of 2 mg/m3. The CO2 concentration during Diwali day is 1.8 times higher than the pre-Diwali day. In addition, the 24-hour mean concentration of TVOC during pre-Diwali, Diwali, and post-Diwali was found to be 915.21 µg/m³, 1513.52 µg/m³ and 1617.12 µg/m³ respectively which is quite higher than normal days. Furthermore, the average noise level in the study site during pre, during, and post-Diwali was found to be 57.71 dB (A), 75.5 dB (A), and 63.66 dB (A) respectively which were higher than the safer limit on the residential zone. As a result of the widespread usage of firecrackers during Diwali festivities, these pollutants are significantly increased, which may have a negative influence on the general public’s health.
