Environment Ministry Introduces Innovative Methods to Control Air Pollution
Trial of various new technologies for air pollution mitigation have been conducted such as Air purification units developed by NEERI for traffic junction pollution, dust suppressant for construction sites and road dust control developed by EPRI, bus roof top filtration systems developed by Manav Rachna International Institute of Research & Studies (MRIIRS), medium scale air purification unit (SMOG TOWER) developed by IIT Bombay and Tata Projects Ltd and ionisation technology developed by S&TP Pune. Out of all these technologies, results of dust suppressant were found encouraging and accordingly advisory issued for its use in Delhi-NCR.
Summary of the project, Sanctioned cost and expenditure incurred on the above mentioned projects is given as Annexure -I.
Central Pollution Control Board(CPCB) has notified the National Ambient Air Quality Standards (NAAQS) in 2009. The method of measurement for all notified pollutants is mentioned in the NAAQS and the ambient air quality monitoring in the country is conducted as per the notified methodology. The revised National Ambient Air Quality Standards is enclosed as Annexure – II.
CPCB Monitors Ambient Air Quality with 15 Continuous Ambient Air Quality Monitoring Stations (CAQMS) comprising 06 in Delhi, 03 in Lucknow, 03 in Bangalore, 03 in Chennai on Real time basis and 07 Manual stations in Delhi. The budget allocation and expenditure over the past three years for operation and maintenance of these CAQM stations is enclosed as Annexure -III.
