Oil-field exploitations that have been done in Moinesti city over the years since 1440 have resulted in soil degradation due to accidents and residual pollution. The location of extraction wells close to the grazing areas has frequently increased questions related to the quality of soil and vegetation for these areas. The aim of the study was to assess the degree of pollution considering total petroleum hydrocarbons and heavy metals in soil and spontaneous vegetation from one of the grazing areas located under the influence of oil pipe transport and oil wells. 35 locations were considered for soil and vegetation sampling and the measured data were mapped and analysed using spatial distribution correlations. The results indicated that, the heavy metal and TPH concentrations in the investigated soils exceeded the thresholds values. They also indicated the existence of residual pollution in the investigated soils. Often, Cd and Pb determined concentrations exceeded the normal values for t.....
