The effect of soil properties on the retention of kerosene in soils, at equilibrium and under venting, was studied. Eleven soils were studied, which represent a wide range of chemical properties and mechanical composition. The retention of kerosene in dry soils ranges from 3.5 to 18.1 mL/(100 g), and was related linearly to clay, silt and organic matter (OM) contents. A coarsely-aggregated dry vertisol (2-5 mm aggregates) retained half as much kerosene as its finely-aggregated (<2 mm) counterpart. Moisture content had a strong inverse effect on kerosene retention. The soil factors that inversely affected kerosene retention also enhanced kerosene stripping by venting. Of these, soil aggregation and porosity were the most important. In addition, kerosene volatilized faster and more completely from an initially moist soil, as compared with an initially dry soil. Differential volatilization of lighter components of kerosene changed the chemical composition of the residue in the soil substantially, as compared with the initial composition. © 1993.
