LUCKNOW: Construction activity in and around Gomtinagar and Alambagh has taken a toll on the ambient air quality. Pollution levels recorded here have shown an increase from last year. It is mainly due to the increase in the volume of ultrafine particles (RSPM) that remain suspended in air for long.

CHENNAI: The level of total suspended particulate matter (TSPM) in the ambient air at a traffic intersection in Vallalar Nagar during the 24 hour period ending 6 a.m. on Tuesday was 248 microgram/cubic metre. The permissible limit is 200 microgram/cubic metre.

New Delhi: This year, the city celebrated one of the cleanest Diwalis. Pollution data showed that November 2008 was cleaner than December 2007 on many counts: Suspended Particulate Matter (SPM) and Respirable Suspeneded Particulate Matter (RSPM)

While the United Nations Environment Programme (UNEP) report on Atmospheric Brown Clouds forming over Northern India has set alarm bells ringing, Delhi has reason to cheer.

Hyderabad Dec. 1: More and more people in the city are suffering from health problems caused by high levels of pollution. Mr Pawan Reddy, an IT professional, went to a hospital because he was suffering from constant breathlessness and was diagnosed with asthma by a pulmonologist. The reasons were obvious.
