Imphal, Nov 17:

So far there is no city or town in Manipur in the list of non-attainment city of the Central Pollution Control Board, said a clarification issued by the Manipur Pollution Control Board (MPCB) regarding a local news report claiming air pollution in the State to be the worst in the NorthEast region.
Highlighting that non-attainment cities are those cities that exceed the standards prescribed by CPCB, it said, at present, there are non-attainment cities in Assam, Nagaland and Meghalaya in the North East.
Further stressing that two Continuous Ambient Air Quality Monitoring Stations have been installed at Manipur University and DM University, it said that the average data generated during the months of March to October, 2022 for Imphal City are more or less near the National Ambient Air Quality Standards.
It clarified that ambient air quality data for a limited short period cannot be the basis for assuming the overall air quality status of the region.
Particulate emissions tend to be on the higher side during the dry season, but, the assertion that air pollution in Manipur is the highest in NE India is not true as it is obvious from the list of non-attainment cities that there are five stations in Assam, two stations in Nagaland and one station in Meghalaya that have higher air pollution levels than Manipur over a period of time, it stated.
Necessary action will be taken up if any station is listed as non-attainment city in the State as per directives of CPCB, it said adding that the main causes for increase in air pollution is due to vehicular emission, construction activities, road development works, harvesting related activities, etc. Regular sprinkling of roads under construction will improve the ambient air quality, it said, adding that the State government has also promoted e-rickshaws in Imphal core areas.
The station at DM University started transmitting Ambient Air Quality Data on a real time basis from month of March, 2022 whereas the station at MU started transmitting data from the month of April, 2022. This monthly air quality data for the two stations are transferred electronically to the Central Pollution Control Board (CPCB).
The statement also highlighted that seasonal variations are there in the Ambient Air Quality and that PM10 is highest at MU in the month of October, 2022 and lowest in July, 2022. PM10 is highest at DM University in the month of March, 2022 and lowest in August, 2022. The relatively higher PM10 at MU is probably due to highway development works under ADB project, it said adding that the Central Pollution Control Board will assess the data on a yearly basis in order to determine the status of Air pollution in Imphal city.
