New Delhi, National Capital Region's particulate matter (PM2.5) is substantially affected by transboundary pollution from Pakistan, with almost 33 per cent coming from the neighbouring nation annually, according to a new report, which also said that the country strongly influences the air pollution in Punjab as well.
The NCR's annual average PM2.5 concentration is 67.9 g/m3 (microgram per cubic metre), with local sources contributing 28 per cent, driven primarily by residential activities, such as biomass burning for cooking, followed by industry, agriculture and transport.
