ABSTRACT
This study investigated the effects of oil dose and soil texture on the analysis results for total petroleum hydrocarbon (TPH) in artificially oil-contaminated soils. The same amount of diesel was mixed with soils having different soil texture, and soil TPH concentrations were then analyzed for comparison. Presence of clay in the soil showed lower soil TPH analysis results than that of sand only. As the clay content was increased in the soil, the lower soil TPH concentration was obtained by incompleteness of solvent extraction. As the organic matter content in soil was increased from 5.2% to 10% (weight basis), a higher concentration of TPH was obtained by TPH analysis. However, at a higher organic content in the soil, 18%, resulted in a lower TPH concentration than those of 5.2% and 10%. Gasoline dose to the soil resulted in a significantly low TPH concentration due to the volatilization of gasoline while soil mixing and analysis. This study results would provide fundamental information either to the expectation of TPH concentration in artificially oil-contaminated soil or to estimation of oil release in the real oil-contaminated site.
