The Central Pollution Control Board (CPCB), after monitoring the sound and noise pollution during Diwali, has found that the generation of suspended particles and harmful gases was low this year as compared to last couple of years. Similarly, the level of noise pollution had also decreased in the city. The monitoring was done at three places in the State capital.
The CPCB continuously monitored the air and noise pollution for 72 hours at three places in the city from a day before Diwali. The three places selected by the CPCB were TT Nagar area, Kamla Nagar and Chhola Road. The monitoring of noise pollution was conducted on all three days in TT Nagar locality and Kamla Nagar from 6 pm to midnight.
In a significant finding, the CPCB reported that despite the directives of the Supreme Court, crackers were burst even after midnight. It, however, stated that the bursting of fire-crackers was sporadic after midnight.
The CPCB drew the inference that the highest suspended particles were generated on Chhola Road and the lowest in Kamala Nagar locality. In TT Nagar, there was significant reduction in air pollution as compared to last two years whereas there was marginal increase in air pollution in Nehru Nagar residential area as compared to last year.
Similarly, the CPCB stated, there was significant reduction of air pollution on Chhola Road. However, among the three days when the air pollution was measured, it was found that there was significant increase in the noise levels in TT Nagar and Kamala Nagar on Diwali day.
CPCB's zonal office at Bhopal had requested the State pollution control boards of Rajasthan, Madhya Pradesh, and Chhattisgarh to monitor the ambient air quality of the main cities during Diwali. However, these reports are yet to arrive.
