Objective: The objective of the study was to determine the effects of dust inhalation on the vital capacity of commercial motorcyclists in Abakaliki metropolis. Methods: 200 subjects participated in this study, 100 commercial motorcyclists (test group) and 100 non-motorcyclists (control group). The mean ± S.D of their age, height and weight were calculated. Vital capacity was measured using a spirometer. A questionnaire and consent form was filled by every participant before the commencement of the study. 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. Original Research Article
