According to the Newspaper,These new 20 air monitoring stations, which will give real time data of particulate matter (PM10 and PM2.5), Sulphur Dioxide, Nitrogen Dioxide, Carbon Monoxide, Ozone, Ammonia, Benzene and weather parameters, will take the number of stations to 48. “They are being installed in different areas -- residential, industrial, hospitals, schools, colleges and stadiums --- in order to give a true representative character of air pollution,” a Delhi government official said. “As per international guidelines, the correct way to know one index for a city air quality is to consider different micro-environments… For a typical metro city, commercial; urban complex; sub-urban; residential; industrial; road side; traffic junction are the micro-environments which should be covered in the monitoring network,” a World Meteorological Organisation report says, regarding the need for different types of areas while monitoring pollution. The real time pollution figures from these stations will be available on the DPCC website. The Central Pollution Control Board will take this data and calculate the overall air quality index (AQI) of all these locations, which will then be displayed on it’s website. “The work has already started. Advanced software is being used so that statistical support can be provided within minutes.
