Level of PM2.5 in India has not surpassed that of China: Govt

Government has rubbished the report brought out last month by the NGO Green Peace India stating that the level of hazardous PM2.5 in India exceeded that of China, last year, saying that its findings were based on the extrapolated and constructed data without field validation.

"The report brought out by the Green Peace is based on the extrapolated and constructed data without field validation," the government said.The steps taken by the government to mitigate air pollution in metropolitan cities in the country included Notification of National Ambient Air Quality Standards envisaging 12 pollutants, formulation of environmental regulation/statutes and promotion of cleaner production processes, among others.

The National Ambient Quality Standards notified comprises of 12 pollutants--PM10,PM2.5, SO2, NO2, O3, CO, NH3, Benzene, lead, Arsenic, Nickel and BaP(particulate phase). The ambient air quality is monitored regularly in 254 cities, towns and industrial areas of the country by the Central Pollution Control Board (CPCB), State Pollution Control Boards (SPCBs)/Pollution Control Committees (PCCs) and NEERI for 3 to 8 pollutants.

Analysis of these data indicates fluctuating trends on the basis of individual pollutants in ambient air.''The value of NO2 in nine cities exceeded the NAAQS of 40 micro gm/metre cube, while the value of PM10, in 38 cities do not comply with the NAAQS of 60 micro gram/metre cube.

The PM10 value in three cities complies with the National Standard of 60 micro gram/metre(annual standard),'' the government said. UNI PR RSA
