New Delhi : Environment Minister Kailash Gahlot on Friday inspected Dwarka sub city, a designated hot spot by the Delhi Pollution Control Committee and took stock of multiple sectors to cjeck the prevailing ambient air quality situation.
The Minister directed the DPCC to undertake a special drive to identify the dusty road stretches and initiate prosecution against the agencies responsible.
South Delhi Municipal Corporation (SDMC) has been directed to undertake mechanical sweeping and extensive water sprinkling in the area.
Local area SDM was also instructed to visit the area and find out locations where construction and demolition waste & garbage are dumped to ensure deterrent fines on land owning agencies.
Mr Gahlot took stock of sectors 8, 12, 14 and nearby places.
The Minister also visited the Continuous Ambient Air Quality Monitoring Station (CAAQMS) of DPCC installed at the Indian Institute of Malaria Research. The scientists explained to the minister the process of Air quality monitoring through CAAQMS.
After going around the monitoring station, Mr Gahlot said :“Delhi truly has a world class air quality monitoring setup. This helps in finding out the air quality in realtime and taking corrective steps.”
The officials informed that monitoring of PM 2.5 & PM 10 is measured by beta alteration technique at hourly bases, this includes measurement of other gases such as Sulphur dioxide, Nitrogen oxide, Carbon dioxide, Ammonia, Benzene and ozone.
It was further informed that CAAQMS is the state of art facility & follows the Standard Operating Procedures approved by Central Pollutional Control Board (CPCB) and the instruments & analysers are United States Environmental Protection Agency (US EPA ) approved.
The Minister has also informed that following steps are being taken for prevention and control of biomass burning including crop residue, garbage burning, Road, Re-suspension dust vehicular Pollution etc are as follows:
• Hotspot Monitoring – 14 identified Hotspots in Delhi to develop action plans to reduce pollution this winter.
• Ban on use of DG sets in Delhi.
• Coordination with State Electricity boards to ensure 24X7 electricity supply
• Dust control measures in Stone Crushers/ RMC plant/ Hot Mix Plant – Regular inspections are being carried out by DPCC
• Dust control measures like cleaning of roads/streets, sprinkling of water to be taken by Municipal Agencies
• 16 Teams formed for keeping vigil on the construction activity, to stop garbage burning and to identify the places where construction and demolition waste were dumped. These teams are keeping vigil even in night hours.
• Delhi’s Ambient Air is influenced by pollution emitted from neighbouring states also. Different studies showed different concentration which comes from neighbouring states in different seasons.
Latest study of TERI shows that in winter only 34% of pollutant is locally originated. In view of the fact, DPCC in collaboration with Washington University undertaking a Real Time Source Apportionment Study which started in March- 2019 and will be completed in 2020.
Once, that study is completed, source apportionment will be available on the basis of real time data which will be more reliable.
