Guwahati/ 17th August’2017 (Prag News Desk): The Central Pollution Control Board (CPCB) have listed five towns in Assam most polluted. In a report issued by CPCB has expressed deep concerns at the rising air pollution in eight towns and cities of the region and has called for a coordinated approach from various stakeholders to control it.
Guwahati, Nagaon, Nalbari, Silchar and Sivasagar, besides Byrnihat in Meghalaya and Kohima and Dimapur in Nagaland are listed as towns consistently becoming polluted since 2011.
These places have consistently recorded higher than acceptable particulate matter (PM10) levels and the CPCB has listed them as polluted cities in which the prescribed National Ambient Air Quality Standards are violated. Thus, the Pollution Control Board, Assam (PCBA) will start monitoring levels of other toxic substances – PM2.5 (smaller particulate matter), benzene, ammonia and carbon monoxide – from this year. So far, the PCBA has been monitoring only PM10, sulphur dioxide and nitrogen dioxide.
