KOLKATA: As a part of a survey to monitor the air quality at prime locations, the World Bank has started installing special monitoring devices at 20 locations across the city.Known as the portable air quality monitoring device, it will be installed atop light posts on the roadside for giving real time data of particulate matter in air (PM 2.5 and PM 2.10). The devices will be set up at a distance of tentatively 2 km in the areas, where the air quality has been found to be very poor due to heavy vehicular movement. The survey by the World Bank will continue till December and if required, such devices might get installed at more locations.

However, it has been found that one or two among the automatic ones often remain defunct. The data available from the manual stations are scrutinised at the international level. According to sources in the state Transport department, the World Bank has already undertaken a project for integrated public transport management in the city. This, air quality monitoring is also a part of the integrated public transport management project.

The Transport department has requested IIT Kharagpur to prepare a report on the ideal number of public vehicles that should ply on the city roads on a daily basis so that commuters have a hassle-free travelling experience. There have been suggestions of making amendments in traffic rules for such an integrated system which is being discussed at the government level. It has been found that air pollution in Kolkata rises to higher proportions, particularly during winter and PM 2.5 reaches alarming proportions. The World Bank, however, will not share the findings of the devices with the common people. The data will be shared with the state government and Kolkata Traffic police so that steps are taken to curb pollution in places where it is found to be alarming. Some years ago, car parking was banned near Victoria Memorial after PM quality was found to be very high.
