Department of Environment has taken 8 hours measurements at several locations along busy roads of Dhaka city. Results show SMP concentrations of 665-2456 ug/m3 at Farmgate. Bangladesh standard for Commercial Area is 400 ug/m3. The SMP trends are highest during the dry season (December-March) due to increase in roadway dust, dust from dust-carrying vehicles, and increased open burning. Figure-1 shows Streetside SPM levels at Farmgate, a busy traffic place in Dhaka. and figure-2 shows PM2.5 urban composition.
