While Indian authorities implemented several measures to reduce emissions from the power, industry and transportation sectors over the last years, such strategies appear to be insufficient to reduce the ambient fine particulate matter (PM2.5) concentration below the Indian National Ambient Air Quality ...
The previously existing National Ambient Air Quality standards (NAAQS) were notified by the Control Pollution Control Board (CPCB) in year 1994 under the Air Act, 1981 for seven parameters i.e.. Suspended Particulate Matter (SPM), Respirable Particulate Matter (RPM), Sulphur Dioxide (SO2), Oxid...
A recent study conducted in Central India shows that the annual mean PM2.5 concentration is three times higher than the National Ambient Air Quality Standards of India (NAAQS) (Deshmukh et al., 2013a). Similar higher concentration was also observed in the National Capital Region (NCR), India ...
EPA is primed to strengthen National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM), known as PM2.5 (particulate matter smaller than 25 micrometers) in 2024. The revised standard, if promulgated, will have near immediate and significant permitting and operating implications ...
Ambient NH3Diurnal variationChemiluminescence methodAmbient NOxMixing ratio of ambient ammonia (NH 3 ) was measured at various locations of the National Capital Region (NCR) of Delhi, India using a NH 3 -analyzer during January 2010 to June 2012 in campaign mode. The present study has been ...
China can obtain substantial air quality health benefits from large-scale fleet electrification, especially in populous megacities34. India’s ambient air quality standard is achievable by mitigating household emission sources and rural electrification35. This methodology can also be extended with additional...
Unsafe water, sanitation, and hand-washing practices are largely responsible for diarrheal disease–related deaths, whereas household air pollution and ambient air pollution are important risk factors for deaths from lower respiratory tract infections in both younger and older children, with undernutrition...

additional toxic emissions due to less stringent diesel car emission thresholds than applied to petrol cars for some 20 years. This holds true as well for many developing countries where less stringent European diesel emission standards are being applied with a time lag. India is a case in point...
