ASSESSMENT OF HEAVY METALS CONTENT OF CRUDE OIL CONTAMINATED SOIL

The concentrations of several heavy metals including Pb, Cd, Cr, Cu and Zn in crude oil contaminated soil samples collected from five oil extraction parks of Dambovita County (i.e. Doicesti, Sotanga, Gheboieni, 2 AR Moreni and 2EPS Moreni) owned by SC OMV Petrom were investigated. The samples were collected in November 2011, from two depths (0-5 cm and 30 cm) and were analyzed by EDXRF technique. The higher concentrations of Pb, Cd, Cu, Cr and Zn were found in all polluted soil samples, thus exceeding the MAL values specified in Romanian legislation. According with these data, it can conclude that each analyzed heavy metal can cause pollution of soil with dangerous implication concerning the environment and health.
