Abstract: Oil pollution of extraction areas is an undesirable phenomenon, but is very present, especially in old farms area.In the context in which the depollution of these areas, in Romania, is carried out from public funds, this fact is more and more difficult to achieve. That is why the effect of pollutants on the environment is being analyzed more and more, it often remains that the depollution is done naturally.This material analyzes the effect of metals present in crude oil(Cu, Pb, Zn, Ag, Ni, Mn, As, Cd, V, Cr, S), on the soil affected by a historical accidental pollution in the Moinesti area, Romania. This article presents the results of analyzes performed by metal detection techniques, namely optical emission spectrophotometry with inductive coupled plasma and atomic absorption spectrophotometry. The metals determined in the polluted soil were statistically analyzed regarding the dispersion, standard deviation and coefficient of variation compared to the control sample and compared with
