Abstract:
The fate and persistence of a petroleum spill under leaching were studied in a field experiment in which the amount of contaminant on the soil surface, the soil moisture status and the leaching pattern were all controlled. Kerosene - a semivolatile mixture of petroleum hyrocarbons - was applied to a sandy loam Mediterranean Red Soil and leached with 500 mm of irrigation and 500 mm of rain water. The field was sampled periodically during 180 days following application and the redistribution and persistence of kerosene components were determined. The major portion of the petroleum product applied to the soils was retained in the upper part of the profile and, despite the amount of leaching water applied, only a slight proportion was transported to the deeper layers. The average residual total concentation of kerosene after 180 days and leaching with 1,000 mm water decreased from 20,000 μg/g soil to 1,900 μg/g soil in the soil upper 20 cm layer. It was shown that soil dissipation and redistribution are the controlling factors affecting the persistence of kerosene components in field soils and that these factors are affected by the properties of the contaminant and the porous medium and the prevailing environmental conditions.
