Abstract
This study was carried out around Zooir oil well in Khouzestan to investigate the concentration of heavy metals (Pb, Cu, Zn, Cd) in soil and two species of plants (Alhagi camelorum and Cornulaca monacantha), two directions of dominant wind and opposite direction of dominant wind and three distances from oil well. The results showed that the concentration of lead, copper and zinc of soil in the wind direction was significantly higher than the opposite wind direction, whereas in the concentration of these elements in the plant, there was no significant effect. This is exactly opposite in the case of cadmium metal. The concentrations of the studied metals in both soil and plants collected from different distances were significantly different at 1% level. The two lead and zinc metals have significant differences in the surface and deep soils, but these were no significant for the cadmium and copper metals as well as in the soils under and between the plants. Heavy metal uptake was no significant effect in the two studied species, but this difference was significant between the shoots and roots. Cadmium and copper have the highest concentration in roots. Lead and zinc have the highest concentration in aerial parts. Evaluation of accumulation and transport factors showed that lead, zinc and cadmium in Cornulaca mocnaantha and lead and zinc in Alhagi camelorum had TF> 1 coefficients, so they could be used to refine soils polluted with these elements. BAC and BCF values for both species were less than one.
