Investigating Effects of Industrial Pollution on the Accumulation of arsenic in Soil and Some Physiological and Biochemical Reactions of Malva neglecta L.

In order to investigate the effects of industrial contaminants on some physiological and biochemical reactions of Malva neglecta L.a factorial experiment was conducted in a randomized complete block design with three replications in farms around the Bandar Gaz  Industrial Estate in Golestan province at spring, 2013. The first factor was the distance from the source of contamination in four levels (control, 100, 200 and 300m) and the second factor was the plant’s organ on two levels (shoot and root). The control plot was also located in the same area at a distance of 1000 meters from the source of contamination. In this study, the amount of Anthocyanin, total soluble sugar, flavonoid, protein, activities of Catalase and Peroxidase enzymes, Glycine Betaine, Arsenic and Cadmium of soil and plant were measured. The highest amount of Anthocyanin (6.37 µmol g-1 of shoot dry weight), total soluble sugar (42.04 mg g-1 dry weight), Proline (15.55 µmol g-1 of shoot dry weight) and Glycine Betaine (46.97 μg g-1 dry weight) were related to the treatment of 200m distance from the source of contamination. The highest amount of protein (0.099 g kg-1 dry weight), Flavonoid (1.305 mg g-1 of shoot dry weight), Arsenic (515.37 mg kg-1 dry weight) and activities of Catalase and Peroxidase enzymes (8.84 and 25.62 μmol H2O2   min-1 respectively) were obtained in the treatment of 100m distance from the source of contamination.
