An ambient air pollution screening study was performed in Dhaka from 31 January – 15 February 2011. The main objective of the study was to gain an overview of the background concentrations and the spatial distribution of the air pollution in the Dhaka city area.

The city of Dhaka was chosen for this assessment due to the current ongoing project Bangladesh Air Pollution Management (BAPMAN), which concentrates mostly on the capital city Dhaka.

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.

The Central Government has undertaken a study, i.e., ‘Air Quality Monitoring, Emission Inventory and Source Apportionment Study for (six) Indian Cities’, namely, Delhi, Kanpur, Pune, Mumbai, Chennai and Bengaluru with the help of premier institutions like, IIT-Bombay, IIT-Kanpur, IIT-Madras, NEERI-Nagpur, TERI-New Delhi and ARAI-Pune for identifying the various mobile and stationary

This is a critical analysis by CSE of the new six-city study on air pollution sources released by Central Pollution Control Board. Says that auto industry is misusing the study to derail tighter emissions standards and encourage polluting diesel cars.

In a number of cities in India, air pollution is a growing problem, not only limited to the megacities, but also spreading through the tier II and tier III cities. Given a diverse mix of sources in these cities, with megacities dominated with transport sector and the secondary

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.
