CHENNAI: The level of respirable suspended particulate matter (RSPM) in the ambient air at residential area in Adyar and traffic intersection in V. Nagar recently was 30 microgram/cubic metre and 185 microgram/cubic metre respectively. The permissible limit is 100 microgram/cubic metre, according to a press release from Tamil Nadu Pollution Control Board.

The present study involves the performance evaluation of the USEPA ISCST3 model for prediction of short-term SO2 concentrations in the ambient environment of NLC complex.

Emerging technologies affect the social, economic and environmental dimensions of our world, often in ways that are entirely unanticipated. A study was carried out to assess the concentration of the critical pollutants, such as sulphur dioxide (SO2), nitrogen oxides (NOx) and suspended particulate matter present in the ambient air of a fertilizer industry during the year 2000.

Long-term human exposure to ambient pollutants can be an important contributing or etiologic factor of many chronic diseases. Spatiotemporal estimation (mapping) of long-term exposure at residential areas based on field observations recorded in the U.S.

NEW DELHI: A new set of data released by Delhi Pollution Control Committee (DPCC) shows a decline in pollution levels in the capital. However, environment agencies say that the numbers are misleading and don't indicate a trend.

During 2010 Games, Real Time Data Will Help Improve Air Quality

Jamshedpur, March 3: Jharkhand State Pollution Control Board (JSPCB) has decided to make online stack monitoring system compulsory in medium and large scale industrial units.

The JSPCB authorities will issue a circular to this effect to all such units and especially to those which have smokestacks.

In this paper an attempt has been made to undertake performance evaluation of the two well-known regulatory models, AERMOD (07026) and ADMS-Urban (2.2) for a tropical city such as Delhi. The model is applied to estimate ambient air concentrations of SO2 and NO2 for the years 2000 and 2004 over seven sites in Delhi. Both model evaluation and inter-comparison is performed.

Asansol city is an industrial urban area which is also part of the Raniganj Coalfield area and is located in the Burdwan district of West Bengal. Over the last five years there was hectic development in the area in terms of industries, vehicles and infrastructures.
