Under the provisions of the Air (Prevention & Control of Pollution) Act, 1981, the CPCB has notified fourth version of National Ambient Air Quality Standards (NAAQS) in 2009. This revised national standard aims to provide uniform air quality for all, irrespective of land use pattern, across the country.

This report contains studies in Chennai and Delhi led by Dr. Kalpana Balakrishnan and Dr. Uma Rajarathnam, respectively.

Incineration of hazardous wastes is one of the sources of dioxin in the ambient air. There are a number of well established technologies to handle hazardous wastes in the form of solids, liquids, sludges, tar etc. and having a high degree of variability in characteristics.

As part of CAI-Asia mission to promote better air quality and livable cities, CAI-Asia conducted an annual review of the main events relevant to air quality, climate change and transport in Asia. This review, which started on 2008 and initially focused on sustainable transport, has now expanded to include air quality and climate events.

The following are excerpts from the final order of MoS, envrironment & forests, Jairam Ramesh, on the Posco steel plant:

Based on its review of the air quality criteria and the national ambient air quality standards (NAAQS) for carbon monoxide (CO), EPA is proposing to retain the current standards. EPA is also proposing changes to the ambient air monitoring requirements for CO including those related to network design.

This paper mainly deals with the measurement of air quality by observing the concentration of pollutants in the atmosphere namely suspended particulate matter, NOx and SO2 at five different selected locations in Lucknow city. The locations for the study have been chosen on the basis of land use pattern. Each pollutant has been observed by 12 hours from 8:00 to 20:00 hours. According to air quality scale, the air quality status has been measured at each location and zone. From the study it is found that the residential zone has highest air quality index in comparison to other zones.

Three key polutants, namely RSPM, SO2 and NO2 have been measured in schools in the National Capital Region (Delhi). Monitoring was conducted at all the 5 locations. Alarming levels of pollutants were reached on Diwali day, a festival of lights and for days preceding Diwali at all the locations.

The Indonesia Air Quality Profile provides background information and findings on the: State of the Air: What is the air quality in cities? Which of the cities in the country are experiencing air pollution challenges or will soon enter into this situation?; Legal framework for air quality management: What is the air quality management system in place in cities?
