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.

(CAMS) at the Sangsad Bhaban Campus, Dhaka
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
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
