【 摘 要 】

This study investigated the impact of crude oil pollution on different types of soils in Kuwait. For this purpose the oil trench, which consisted of diversity of soils was studied. Several boreholes were made to determine the extent of oil contamination in the soil matrix and its effects on soil chemical properties. The highest depth of oil pollution was measured in the Typic Torripsamments and Typic Petrogypsids and the highest width was at the Typic Aquisalids. This variation is due to physical and chemical characteristics of soil and the depth of the hardpan. Soil samples were collected from the different soil type layers in the oil trenches and also from reference (control) sites to compare the total petroleum hydrocarbon (TPH), total extractable matters (TEM) levels, soil pH, CaCO3 and electrical conductivity (ECe). The Typic Calcigypsids soils showed the highest concentration of TPH and TEM, which were significantly higher in the oil trench by 99% than control. The soil pH and CaCo3 were reduced in presence of oil and the soil ECe was significantly altered at the 95% level of confidence. The study showed that soil types behaved differently with crudeoil pollution.
