entific methods. We have carried out an assessment on the environmental effects of limestone quarrying on some communities in the Lower Manya Krobo District in the Eastern region of Ghana. Dust emission is one of the major effects of the practice of limestone extraction and as such, dust (PM10) sampling was conducted at the affected communities.
Mining, processing and transporting sand generate large quantities of silica dust, which is notorious for the damage it does to the lungs and respiratory system when inhaled. In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called "fracking," has led to boom in sand mining across the upper
