AN ASSESSMENT OF THE EFFECTS OF CRUDE OIL POLLUTION ON SOIL PROPERTIES

Pollution caused by crude oil is the most prevalent problem in the environment. The release of crude o il into the environment by oil spills is receiving worldwide at tention. The effect of crude oil pollution on soil properties was investigated by achieving a case study in Perisoru, Braila County. It has been achieved a profile unti l 120 cm and soil samples were collected according to the methodology and analyzed for some physical and chemical proper ties. In case of physical analysis, the values obtained for granu lometric fractions were not influenced by the prese nce of crude oil. Results obtained showed variation in chemical prope rties of soil. Organic carbon increased from 2.23% for an unpolluted soil to 5.51% in polluted soil. C/N rat ios increased from 13.01 for an unpolluted soil to 20.54 in polluted soil. Mobile phosphorous and potassium registered i n polluted soil similar values with the one charact eristic for unpolluted soil. Crude oil at high pollution levels inhibited the growth of crops.
