Neighbour states responsible for pollution in Delhi

Latest study in Delhi highlighted that neighboring states are responsible for 60 per cent of the pollutants. Study further mentioned that there is need for a regional strategy to tackle air pollution in Delhi and north India.

 

Only 40 per cent of the particulate matter (PM) 2.5, a major pollutant in Delhi air Delhi is generated in the capital, according to a study.

 

Remaining 60 per cent comes from neighbouring states, stated a study conducted by scientists at the National Environmental Engineering Research Institute (NEERI).

 

The International Institute for Applied Systems Analysis (IIASA) also participated along with NEERI to obtain the study results. It highlighted the need for a regional strategy to tackle rising air pollution in Delhi and entire north India.

 

Standard for PM 2.5 in India is 60 microgram per cubic metre. As much as 20 per cent of PM 2.5 is contributed by transport sector.

 

Other sources of PM 2.5 are burning of biomass, secondary inorganic aerosols formed through emissions by thermal power plants and industrial emissions.

 

The research identifies a range of measures with major emission reduction potentials including, reducing the road dust emission, clean cooking fuels in Delhi and its neighbouring states.

 

"Comprehensive management of agriculture and municipal waste, a ban on open burning of waste are some other measures,” said Padma Rao, co-author of the study.
