In the production of coal West-Bokaro area of Central Coalfields Limited, Ranchi plays a vital role. During the production of coal, it produces huge quantity of suspended particulate matter (SPM), respirable particulate matter (RPM/PM10) as well as gaseous pollutants. Which polluted the area badly.

In a unique experiment, British scientists on Tuesday turned pedestrians, cyclists and vehicles into mobile wireless sensors to measure air and noise pollution.


Ranchi, June 10: Now, you can study the level of pollution in your city.

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.

New Delhi: Weeks ago, when Modern School student Akkriti Bhatia succumbed to an asthma attack while in school, most blamed the school for tardy medical action. But perhaps air pollution in school areas is also to blame.

A study by The Energy and Research Institute (TERI) profiling air pollution in schools between 2002 and 2003 has thrown up alarming results.

Air pollution levels in the megacities of Asia show a stabilizing trend but still exceed World Health Organization guidelines. Studies also show poor air quality, not only in the megacities of Asia, but also in smaller cities with populations of 150,000 to 1.5 million. While megacities often receive support for improving air quality; similar assistance seldom reaches smaller cities.

Chennai: The level of respirable suspended particulate matter (RSPM) in ambient air at a traffic intersection in T.Nagar during the 24-hour period ending 6 a.m. on Saturday was 137 microgram/cubic metre.

The permissible limit for RSPM is 100 microgram/cubic metre.

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.


Air conditioning in cars cuts out more than 80 per cent of germs, fungal spores and particles from outside air, providing a boon for people with respiratory problems or allergies, German scientists say.

National Task Force consisting of the representatives of the relevant sectors will be set up on control of Asthma while a joint action plan would be drawn up for control of Asthma through a participatory process.
