In a month's time, Delhi will start retrieving detailed reports on the composition and contribution of various sources of pollution, Gopal Rai, Delhi’s environment minister shares on Thursday.
The real-time source apportionment set-up, which has been installed by Delhi government in association with Washington University, is apparently going to be functional soon, and its first report is going to be presented by March, said Rai.
The newly-appointed minister said he would be visiting the headquarters of Washington University in Delhi on Friday to see the scientists and understand how the info might be utilized. “We had a variety of studies on source-apportionment administered within the past, but these are old studies now. Tons have changed in Delhi since. Not only can we got to know the very best source of pollution, but also how this change every few months,” Rai said.
In the meantime, DPCC officials said the project would be ready to provide accurate data on the contribution of every sector in both summer and winter, allowing them to act on the sources of pollution. A DPCC official has reportedly revealed that the real-time data is vital to ascertain the development in each sector. If the contribution from the transport sector is going to be high, they will aim at reducing congestion on roads. If it's from industries, their teams can specifically target them and check for clean fuel usage.
While the primary report is going to be made available in March, DPCC officials said a choice was yet to be taken on how often the next reports would be released. They have organized several meetings over the past few months. After the ultimate calibration, data are going to be available from April. it'll even be provided to our teams for further action, the official further divulged.
The real-time source apportionment is going to be done using analyzers installed at one location initially. particulate is going to be taken into consideration from 26 air quality monitoring stations. Real-time monitoring and sampling of PM1, 2.5 and 10 are going to be administered additionally to the varied aerosols and compounds, the official said. As a part of the study, an algorithm is additionally being developed to assist DPCC to analyze long-term data, he added.
In January 2019, the govt had signed an MoU with the Washington University to work out real-time sources of pollution through the year. A long-term source apportionment study, however, may take 1-2 years to finish.
