Exposure to hydrocarbon products has been associated with numerous health risks and toxicities. Outdoor or indoor occupational exposure to highly volatile and lipid-soluble hydrocarbons has been linked to impairment of respiratory, cardiovascular, and liver functions. This study is aimed at determining the potential impact of occupational exposure to liquefied petroleum gas (LPG) in varying work environments. Respiratory symptoms, oxidative stress, cardio-pulmonary, and liver function parameters were assessed among LPG workers in the Kano metropolis, Nigeria. Study subjects were recruited from LPG filling stations and street LPG retail shops. Results of the study showed that the forced vital capacity (FVC) of LPG station workers was significantly lower (2.81 L/min; H = 22.473, p 0.001) relative to the values recorded among LPG retail shop workers and the controls (3.54 L/min and 4.24 L/min respectively). A similar reduction was seen in the forced expiratory volume in the first second (FEV |
