摘要：This study examines the impacts of cement dust emissions on physicochemical properties of soils within 10km radius from the plant (factory) in Ashaka area, Gombe State. Standard procedures used in soil sampling involves collection of soil samples along a transect aligned in the north-east to south-east direction in order to reflect the dominant two opposing air masses direction; the north-easterly (November-April) and south-westerly (May-October) air masses. Physicochemical analysis of the soils was carried out using standard laboratory procedures in the laboratory. Results of the analysis has revealed that the cement dust which contains high calcium has impacted the soils by increased soil pH, calcium (Ca) content, total bases, base saturation and pH dependent cation exchange capacity (CEC). The impact is observed most within the radius of 0-5km from the plant with a diminishing impact from the 5km towards the 10km radius. Similarly, results of the analysis has shown also that there are signs of slight impaction of bicarbonate (HCO3) and electrical conductivity (EC) arising from the cement dust on the soils. Recommendations were offered to monitor the dust falling on the soils through trapping and utilizing the dust emissions to cement.
