New Delhi: Close to winter, Delhi immediately found himself in a scenario that was too familiar with the smoke fog.
However, only 36% of these are done by Delhi himself.
Track the level of pollution in the study of the distribution of your new sources together was carried out by the Energy and Resources Institute (TERI) and the Automotive Research Association of India (Arai) showed that 64% of PM2.5 pollutants bleed Delhi from the regions upright in neighbors.
State, the rest is generated locally.
This again highlighted the need for an ‘air warehouse’ approach to handling air pollution in the region.
Vehicle emissions are said to take 30% of the load of Delhi PM2.5 in the winter.
Another contributors are burning biomass (23%), industry (20%) and dust and construction (16%).
The study of this source distribution, the latest for Delhi, was carried out in 2018.
While the Delhi government contracted for a real-time study in 2020 to the University of Washington, then considered unsatisfactory and new studies were given to Teri, Iit Delhi and IIT Kanpur.
The result is expected this winter.
According to Teri’s research, Delhi also contributed 40% to noida winter pollution.
Overall, Delhi’s part in pollution in the city of NCR an average of 16%, indicates a cross-border transmission of pollutants.
The report said, “The average contribution of Delhi’s own emissions itself in PM2.5 concentration was found 36% in the winter and 26% in the summer, the contribution of outside sources was higher due to higher wind speed and increased atmospheric transportation From pollutants -Sumber based Delhi in summer and winter, “experts treat the area as airshed is very important if winter pollution is to be handled efficiently.
In his winter action plan, the Delhi government did register coordination between countries as the main focus area, with the Minister of Environment Gopal Rai supporting the airshed approach.
Dipankar Saha, former Head of the Central Pollution Control Board Air Laboratory, said air pollution could not be limited to an area and all indo-gangetic plains were influenced every winter.
“As a airshed area, the entire NCR region can be taken into account, even Punjab and Haryana, where pollutants burn stumps,” said Saha.
“Every country needs to act based on the source simultaneously to realize the overall increase.
If only one country increases air, the pollutants transmitted by wind from neighboring countries can still cancel efforts.” Talking about fixing Delhi air pollution problems, Karthik Ganesan, colleagues and Director (Research and Coordination), Council of Energy, Environment and Water, said, “The main focus of the restrictions on winter pollution must depend on the forecasting tools of loyalty that prepares agents who prepare before events of various severity.
The time enforcement of systems such as plans The activity of multilevel response is very important.
Limiting activities alone will not be enough.
