As a consequence of industrial development, the environment is increasingly polluted with heavy metals. Plants possess homeostatic mechanisms that allow them to keep correct concentrations of essential metal ions in cellular compartments and to minimize the damaging effects of an excess of non-essential ones. Phytoremediation is an environmental contaminant cleanup technique that utilizes the plant’s natural metal ion absorbing behavior. During the exposure of plants to contaminated soils the antioxidant defense system helps the plant to protect itself from the damage. In the present work the plants Brassica juncea and Sorghum vulgare which are widely cultivated for their agronomical value, were exposed to the heavy metal Chromium contaminated soils and their biochemical factors, vitamins and minerals factor and antioxidant factors were investigated. From the results it is evident that the heavy metal chromium affects significantly the biochemical factors, vitamins, mineral factors and antioxidant factors more in Sorghum vulgare than Brassica juncea.
