Air Quality Monitoring and Evaluation  

Air quality monitoring and evaluation is a vital part of an air quality management plan. DoE is developing an air quality monitoring network in the urban areas of Bangladesh. The first stage was the development of a Continuous Air Monitoring Station (CAMS) at the Sangsad Bhaban campus in Dhaka. The station was officially opened in April, 2002.

DoE is currently evaluating sites for additional air quality monitoring stations in Dhaka and is aiming to have at least 3 of these stations operational by 2004. Further expansion of the network in Dhaka and in Chittagong and Khulna is planned for 2005.

The CAMS provides continuous measurement of CO, NOx, SO2, O3, Non-methane hydrocarbons and meteorological parameters. Batch sampling of PM10 and PM2.5 is also carried out in parallel.

The monitoring at CAMS to date has shown that ambient concentrations of particulate matters significantly exceed air quality objectives. During the winter period PM levels increase very significantly. However, during the monsoon period the rain reduces ambient PM concentrations. Concentrations of gaseous pollutants are generally within the air quality management objectives. However, further monitoring is still required.

Reporting on Air Quality

DoE’s air quality reporting includes the release of a daily Air Quality Index, a monthly air quality report and an annual air quality report. All air quality data except air qaulity index can be found on reports page.
