Abstract
Associations between high level of occupational dust and cardiovascular diseases have been known for more than half a century.To evaluate the effects of quarry dusts on the electrocardiogram of quarry workers in Abakaliki metropolis. They were within the age of 18 to 65 years. A questionnaire was issued to obtain some vital medical and workplace information. Signed consents forms were obtained. An electrocardiogram machine was used to examine the electrical activities of their hearts. A handheld laser dust measuring device called air sampler PCE-PCO 1 was used to analyze the quantity, quality and sizes of particulate matters present in the research area. Data were presented as Mean ±SEM, analyzed using a 2-way ANOVA, and a multiple comparison test using Tukey's Post Hoc Test. Level of significance was set at 95% confidence interval. All statistical analyses were carried out using Graph Pad prism 7 software.
