Environmental pollution by heavy metals has been on the rise in recent times. Cement manufacture is one of such activities that contribute to environmental pollution through the emission of gasses and cement dust. Cement dust is largely made up of cement-kiln that is a by-product and it is usually stored as waste in open-pit and unlined landfills. This dust can spread over large areas through wind and rain and are accumulated in and on soils and plants. Some of the metals usually found in the dust emissions fr
