“…PM 10 ) on BFN. Large celebratory events using fireworks, such as Diwali in India, which last several days, enhance air pollutant concentrations sufficiently that it can be detected from space through tropospheric column NO 2 and aerosol optical depth (AOD) measurements (Sati and Mohan, ; Devara et al ., ). This is despite the large uncertainties/errors associated with satellite measurements.…”

UK Bonfire Night (BFN) is an annual event on 5 November which celebrates the failed ‘gunpowder plot’ of Guy Fawkes, who intended to blow up the Houses of Parliament. This event is celebrated with firework and bonfire displays, which reduce visibility and increase air pollutant concentrations. A two‐ to four‐fold increase in particulate matter concentrations was seen at some surface monitoring sites. Satellite measurements of aerosol optical depth found increases of 10–90% between days before and after BFN.

“…Satellite measured Aerosol Optical Depth (AOD), a measure of PM quantity distributed within a column of air from the Earth's surface to the top of the atmosphere, can also be used to understand and investigate the effect of fireworks on visibility and air quality (Kessner et al, 2013;Khor et al, 2014;Pope et al, 2016;Wu et al, 2014;Zheng et al, 2017). Devara et al (2015) reported an approximately four-fold increase in AOD values during the Diwali festival in India. These results are similar to the observations in the UK where a significant increase (2-4 fold) in the aerosol loading during Guy Fawkes Night was reported (Pope et al, 2016).…”

“…As a part of celebration, crackers are fired. Fire crackers are classified into those exploding at the ground level and in air (Devara et al., 2015). Crackers contain chemicals such as salts of potassium (K), sulphur (S), manganese (Mn), sodium (Na), aluminum (Al), iron (Fe), strontium (Sr), barium (Ba) and charcoal (Wang et al., 2007).…”

Diwali is celebrated widely in Asian countries, with a custom of firing crackers. Crackers pollute the environment with noise, particulate matter and chemicals. There are reports on the variation of particulates during firing crackers but none on airborne microbes. The present study was conducted to know the impact of fire crackers on airborne microflora. The air samples were collected 3 days prior to Diwali, on Diwali and 3 days after Diwali during the year 2017 at 15 different areas in Chennai, India. Andersen N-6 viable particle air sampler was exposed with petridishes containing nutrient agar and potato dextrose agar for the isolation of bacteria and fungi respectively. An average of 1,904 ± 2.5 CFU/m 3 of bacteria recorded prior Diwali was reduced by 53.23% on Diwali and increased by 27.37% after Diwali. This reduction on Diwali is attributed to the exposure of bacteria to chemicals emitted by the crackers. For fungi, an average of 235.57 ± 1.67 CFU/m 3 was recorded prior Diwali, with an increase of 78.5% on Diwali. The increase in fungal count might be due to the release of spores by ground crackers. The study shows that bacteria are susceptible to the chemicals emitted by fire crackers when compared with fungi.
