Study the possibility of refining gas refinery Bidboland Behbahan soils surrounding land by hock

The presence of heavy metals pollution in agricultural soil and its products, one of the most important ecological problems in the world. Refinery gas pollutants in the region, is one of these resources through the air, waste and other methods can be contaminated. In order to determine the amount of heavy metals in surface and hock (Malva Silvestris) Soil samples Bidboland and evaluation of refinery pollution levels, with 54 surface soil samples and 30 samples were collected and the amount of heavy elements hock (Malva Silvestris) cadmium, mercury, vanadium, lead, chrome and arsenic using atomic absorption spectrometry (ICP) were analyzed. The results of analysis of soil samples The average value of the metal, mercury and arsenic, while the lowest was recorded for cadmium and vanadium. The maximum coefficient of variation of lead in any case, the concentration of heavy metals in soil samples from the process following cl aim As> Hg> Cr> Pb> V> Cd. Comparing these results with international standards shale shows that the concentration of Elementsin the study area is less than standard. The plant, for example, the highest average value of the metal to hock, for cadmium (ppm 2/46) to the East, and the lowest mercury (ppm 0/47), and chromium (ppm 0/61) both for North was recorded. In any case, the concentration of heavy metals in plant samples follow the process below: Cd> As> Pb> Hg> va> Cr. Also the highest concentration of biological index related to the element cadmium (3/09-3/98) and the lowest in chrome (0/66-1/69) respectively.
