Unfortunately, the story of environmental lead in Bangladesh is still unfinished and further decline is likely to be comparatively slower. There is a substantial amount of accumulated lead in dust from earlier depositions and this is going to be around for a considerable time to come. Although, vehicular emissions from the use of leaded gasoline were considered to be the single major source of lead pollution in the atmospheric air, yet there are other sources as well. For example, lead is still being used in an uncontrolled manner in paint, battery and other industries. It is therefore, essential to continue the fight for decreasing lead level in atmospheric air through the removal of lead in paints and through control of emission from related industries such as lead based battery industries by regulatory measures.
Further study is underway in the BAEC laboratories to see the long-term effect of using unleaded gasoline on the lead concentration in atmospheric air.
