New Delhi: With the rainy season near the end, Delhi is getting ready for winter, when air pollution reaches the top.
Changes in the wind because the rainy season began to withdraw from the area leading to a decrease in speed and wind temperatures, both of which trapped local pollutants and winds from neighboring countries.
The winter action plan to combat pollution is expected to be released at the end of September.
While the data since 2015 did indeed show an average of PM2.5 which reduced every year, an anti-pollution plan must consider that Delhi still needs to reduce the annual PM2.5 burden of 58% to meet national air quality standards.
Track the level of pollution in Cityin 2020 you, when the city goes to lock because Covid-19 and determines the level of pollution of ‘base’ which can be achieved if the main sectors are regulated, capital still does not meet the national security standards of 40 micrograms per cubic meter for PM2.5 , note the reading of 96 micrograms per cubic meter.
Analysis by the Center for Science and Environment on behalf of the central pollution control board data from five oldest air quality monitoring stations in Delhi – Ito, IHBAS, Mangir Marg, Puram RK and Punjabi Bagh – showed an annual average of PM2.5 in 152 micrograms of cubic meters on In 2015, but it fell to 127 in 2016, 120 in 2017, 118 in 2018 and 109 micrograms per cubic meter in 2019.
In 2018, Delhi had 36 air monitoring stations and the average concentration of PM2.5 years was based on all 36 The station is 112 micrograms per cubic meter, still three times the acceptable limit.
“The latest data is related to 2019 because in 2020, data collection is affected by locking,” said Anumita Roy Chowdhury, Executive Director, Research and Advocacy, CSE.
“It is still clear that Delhi needs a large increase in all sectors to achieve national standards for PM2.5.” Based on the average three-year method, however, when the annual average reading of the 2018-2020 was taken, the annual average of Delhi PM2.5 was 105 micrograms per cubic meter, which Chowdhury explained that the determination of average pollution was more accurate levels .
“Particulate pollution has begun to stabilize and refuse, but capital still needs to reduce the annual average of PM2.5 around 60%.
There is a big gap in the current action.
There is a need to increase public transportation, adding to the infrastructure to run and cycling and implement parking restraintances for Reducing traffic volume.
Delhi also needs to achieve electrification vehicles 25%, control pollution in small and medium-scale industries and see the waste management infrastructure, “Chowdhury said.
Dipankar Saha, former CPCB air laboratory head, said that with local action, there must be coordination with other countries to ensure that burning and dust stumps, two external factors, do not add to the local burden.
“Until the aravalis is made green again, dust will be significant with the wind blowing from Rajasthan towards Delhi.
Stainble Burning, meanwhile, is 30-40% of the PM2.5 Delhi burden on the fire peak period,” Saha said.
Delhi must cut PM2.5 by 58% to meet the annual standards
