New Delhi, Nov 7 (PTI) The Centre for Science and Environment (CSE) today blamed the thick smog observed over the NCR region today to rising pollution and urged the Centre to notify proposed new air quality standards at the earliest.

Even as the government agencies maintained that smog was a routine phenomenon observed during the winter season, CSE felt its presence reflected that Delhi's air was increasingly becoming more polluted and unbreathable, bringing back the pre-CNG days.

Based on its latest analysis of recent air quality data in Delhi, the environmental organisation said that in 2001, when the CNG programme was on, the annual average level of respirable suspended particulate matter (RSPM, or PM10) in residential areas stood at 149 microgram per cubic metre.

"After registering a drop in 2005, the level has shot up to 209 microgram per cubic metre in 2008.
