Abstract

The effect of diffusivity of petroleum products on human health in contaminated areas was investigated. The diffusivity of light naphtha, different brands of gasoline, gasoline-ethanol blends, and jet fuel were examined as a function of temperature. The diffusivities were related to the density, vapor pressure, and the types of hydrocarbons present in each product. The diffusivity of different gasoline-ethanol blends was also studied. The temperature has an effective influence on diffusivity. The increasing of atmospheric temperature means an increasing in the diffusivity and increasing in the impact of human health and especially in closed areas as hydrocarbon vapors contaminated area.
