Diwali celebrations in the city pushed the noise level and air quality index to moderate level in several parts of Ujjain with fireworks choking the city well past 11 pm on Wednesday. Despite the orders of supreme court capping the time of bursting firecrackers from 8 pm to 10 pm on Dipwali nothing much was impacted and data also shows the same picture.
Noise level’s normal limit is 55 decibel in a normal day and 45 decibel during night, noise above these limits can harm human beings. Recent data collected in residential areas of the city shows that noise level rises steeply to 122 decibel on the night of Diwali which is approximately triple the prescribed limits of noise level.
The ambient air quality data of particulate matter (PM) 2.5 and 10 and sulphur dioxide and nitrogen dioxide pollutants taken from both commercial and residential areas shows that the air quality has breached the normal permissible limit as PM 2.5 level of commercial area. On Diwali it was 106 microgram/cubic metres and PM 10 level was 180 microgram/cubic metres which is higher than previous year’s air quality level and comes in moderate level of air pollution index.
Similarly, in residential area PM 2.5 level and PM 10 level were 72 and 152 microgram/cubic metres, respectively. Sulpur dioxide level in commercial areas and residential areas are 21.5 and 19.6 microgram/cubic metres, which is higher than previous year.
Similarly nirogen dioxide level in commercial areas was around 23.2 microgram/cubic metres, which was 20 per cent higher than previous year’s level and in residential areas it was 22.5 microgram/cubic metres, which was 50 per cent higher than the previous year’s sulphur dioxide level. Twin impact of rising pollution level and advent of winter season could have a lasting impact on the health of citizens.
Taking cognisance of religious sentiments of citizens supreme court had allowed bursting of firecrackers from 8 pm to 10 pm on Diwali and other festivals. It had also allowed manufacture and sale of only “green crackers,” which have low light and sound emission and less harmful chemicals. SC further asked police officials to control the bursting of firecrackers after 10 pm.
