The study analyzed the impacts of dust generated from the crushing plant (point source) to its immediate environment in Gbose Quarry. The objectives of the research were achieved through sample collection from the study area and quantitative method. The collected samples were labelled SS1, SS2, SS3, SS4, SS5, SS6 and SC. The samples were taken to the laboratory for analyses using atomic absorption spectrometer (AAS). The results obtained from the laboratory were subjected to statistical analysis using SPSS. Analysis of variance (ANOVA) was employed for between and within group comparison while student’s test was used for paired comparison. The T-tests associated with all the elements (silicon, aluminum, iron, calcium, zinc, lead, potassium, strontium, bromine, europium, hafnium, bismuth, niobium, and manganese) present and pH were found to be significant at p < 0.05. Questionnaire which serves as the quantitative method was also prepared. The prepared questionnaire was administered to 30 quarry workers and 50 nonquarry workers. The results obtained from the questionnaires showed that quarry workers are more exposed to the effects of dust than the non-quarry workers due to the proximity. About 80% of the quarry workers have the symptom of silicosis and pneumoconiosis caused by inhalation of dust particle and those having the same symptom are less than 50% and no chronic condition was recorded.
