Abstract:

Pollution caused by crude oil is the most prevalent problem in the environment. The release of crude oil into theenvironment by oil spills is receiving worldwide attention. The effect of crude oil pollution on soil properties wasinvestigated by achieving a case study in Perisoru, Braila County. It has been achieved a profile until 120 cm and soilsamples were collected according to the methodology and analyzed for some physical and chemical properties. In caseof physical analysis, the values obtained for granulometric fractions were not influenced by the presence of crude oil.Results obtained showed variation in chemical properties of soil. Organic carbon increased from 2.23% for anunpolluted soil to 5.51% in polluted soil. C/N ratios increased from 13.01 for an unpolluted soil to 20.54 in pollutedsoil. Mobile phosphorous and potassium registered in polluted soil similar values with the one characteristic forunpolluted soil. Crude oil at high pollution levels inhibited the growth of crops.
