The present study investigated environmental impacts of cement production on surface water quality and vegetation around the vicinity of the industry. A two-year study was conducted covering both wet and dry seasons. Water samples were collected from Akinbo River where the Cement industry discharges its liquid waste/effluents. Samples were analysed for physical and chemical parameters using standard procedures. The vegetation around the factory was studied for chlorophyll, plant density, basal areas and heights of woody species. The study also assessed the health impacts of cement production activities on the workers and the residents around the factory. The health assessment was based on the hospital information obtained from two clinics in the nearby villages. The water quality results revealed high concentrations of Ca and Fe. All the trees sampled around the study area had small basal areas and short heights. There was also a significant reduction in the chlorophyll contents of vegetations around the cement factory. The health study showed a high incidence of upper respiratory tract infections, cardiovascular diseases, arthritis, and dermatitis among the cement factory workers. The present study suggests an upward review of the dust-suppressing system in use by the industry for the protection of public health. |
