The study examined the impact of soil contamination with crude oil on the developmental stability of the plant Vicia faba L. - broad bean as well as the amount of heavy metals in soil and plant leaves. The experiment was conducted under laboratory conditions with the influence on soil various amounts of oil addition. Deviations from the stability of plant development were studied based on the amplitude of fluctuating asymmetry indicators of bilaterally symmetrical broad bean leaves. Research has shown that the level of soil contamination with oil is directly proportional to the values of fluctuating asymmetry indicators. The heavy metal content (Mn, Fe, Zn, Cu, Co, Pb, Ni, Cr, Sr and V) in the soil and leaf samples was determined by X-ray fluorescence spectroscopy. The main advantages of XRF spectroscopy technique is non-destructive sample preparation - the absence of the stage of destruction of the soil and vegetal samples by chemical reagents or high temperature. The capacity of V. faba plant to extract and accumulate heavy metals in leaves was determined by using the bioaccumulation coefficient. It was found that V. faba leaves accumulate Zn and Cu. The results of this study may be useful for assessing the feasibility of using broad bean as an ecological indicator and remediator of oil-related soil pollution.
