Kolkata, Feb 9 (PTI): Electro magnetic display boards (EMDs) were on Wednesday installed in the city to display air pollution levels, by the state-owned GAIL (India) Ltd and the West Bengal Pollution Control Board. The EMDs, put up at some important crossings, would display the level of sulphur dioxide, nitrogen oxide and suspended dust particles in the air along with temperature and humidity.
Speaking on the occasion, WBPCB chairman Sudeep Banerjee said the data input would be provided by the air quality monitoring stations of the PCB at different places. Claiming that Kolkata was "not the most polluted metropolis in India," as was commonly perceived, he said the PCB along with the state environment department had been able to drastically reduce the air pollution level in recent years.
Environment and IT minister Manab Mukherjee said the Kolkata Municipal Corporation has undertaken a large-scale initiative to make the city greener and cleaner. GAIL director (marketing) U D Choubey said the company’s proposed venture to source CBM from Asansol or Jharia to supply CNG to the city would help contain vehicular pollution significantly. GAIL has spent Rs 20 lakh for the EMDs and plans to put similar boards in some other points of the city.
