Five designs and technical studies for targeted solutions and induced-draft air treatment systems at major traffic intersections in the city are a part of six immediate measures to be implemented by the government to check air pollution.
The decision was taken at a meeting chaired by Deputy Chief Minister Manish Sisodia. Environment Minister Imran Hussain and officials of Public Works Department (PWD), environment and Delhi Pollution Control Committee were present.
The ideas and their proposals are the result of scientific reports of Government of India by Central Pollution Control Board (CPCB), Council of Scientific & Industrial Research (CSIR) and National Environmental Engineering Research Institute (NEERI) and the orders of the National Green Tribunal (NGT).
Induced-draft air treatment systems will be installed at five major traffic intersections by NEERI in collaboration with the PWD. The IDC at IIT Bombay will help NEERI design for these traffic intersections. Such a unit has the potential to reduce carbon monoxide and particulate emission by 40%-60% emission in 20-30 m
radius during peak traffic hours.
Sisodia ordered that the DPCC conduct the five studies along with NEERI, which will result in concrete deliverables and help to check air pollution.
The National Environmental Engineering Research Institute (NEERI) of the Central government will design and implement these solutions. The pilot study executed in IIT Bombay on JVLR Road shows reduction of 55-76% for PM2.5 and 73-88% for PM10. Air quality sensors, anemometers, camera and counters will be mounted on these units for better mapping which will enable robust data assimilation and analysis.
This will also execute directions of the Central Pollution Control Board (CPCB) to DPCC dated 29th December 2015, which requires action on creating green buffers along traffic corridors, and reduce kerbside pollution and intervene at road traffic intersections using different technologies.
