摘要

Gasoline vapour emission is an insidious topical air pollution and hazardous health issue underestimated at both storage and utilization levels.Since gasoline station is one public built environment found in every locality,the problem of unguarded vapour emission through this facility needs serious attention.This study measures the close relationship between the emission rate and the ambient properties with specific objectives including evaluating operational emission level and determining the correlation coefficient.Field measurements of evaporated quantities were conducted at selected station in Enugu State.For the random variation in emission quantity,the wheel spun approach was used to obtain all round mean value per month.Also,meteorological records of Nsukka municipal city for the period under consideration were obtained and analyzed for possible relationship by calculation of coefficient of correlation.The findings from this study suggest that gasoline evaporation is strongly correlated with ambient temperature and wind speed variations,respectively.Thus,high concentration of emitted gasoline on a hot day constitutes a potential thermal mass,high in embodied energy and if excited by light wind speed,can flow many distances away from the station.This insightful information on the emission will be useful to environmentalist and decision makers and has potential to bring about policy changes within the industry.
