Abstract:Soil polluted with crude oil is one of the most serious environmental problems in the world, which is mostly caused by human activity. Crude oil-associated heavy metals in the polluted soils are still considered as one of the major issue around the globe. Two soils were polluted with crude oil at levels of 0.0, 1.25, 2.5, 5, 10, 15 and 30 ml.kg−, then concentrations of heavy elements were added, 30 ml.kg− and 140 ml.kg− for lead and nickel and 40 ml.kg− and 150 ml.kg− for copper and zinc. When adding levels of… Show more
