Abstarct: In order to investigate the effects of different cadmium and arsenic in the aerial parts and roots of Lemongrass plant, a potted experimental experiment was conducted in a randomized complete block design with three replications in Shirvan Higher Education Complex in 1400. Experimental treatments included four levels of arsenic at A1 = 0, A2 = 10, A3= 20 and A4= 30 mg / kg soil from sodium arsenate source and four levels of cadmium at C1= 0, C2= 10, C3= 20 and C4= 30 mg / kg soil were from cadmium sulfate source. The results showed that the interaction of arsenic and cadmium had a significant effect on chlorophyll a and leaf carotenoids in lemongrass and reduced them. Fresh and dry shoot weight and dry weight as well as lemongrass root length were also significantly affected by the use of arsenic and cadmium. Meanwhile, the concentration of nitrogen, potassium and phosphorus in the leaves of Badabjavieh decreased with the use of arsenic and cadmium. This reduction in treatment of 30 mg / kg arsenic compared to the control for nitrogen, potassium and phosphorus were 38.3%, 43.5% and 16.1%, respectively. Cadmium was 18.5%, 26.4% and 29.1%, respectively. The activity of antioxidant enzymes catalase and superoxide dismutase in leaves was affected by the interaction of arsenic and cadmium and their activity increased with increasing concentration of cadmium and arsenic in soil. The concentrations of cadmium and arsenic in the aerial parts and roots of lemongrass were significantly changed in this experiment, so that the highest amount of cadmium and arsenic in the aerial parts were 21.7 and 0.85 micrograms per gram, respectively, and in the roots, respectively. Were 27.3 and 42.2 micrograms per gram of dry matter, respectively. These values were obtained when using 30 mg / kg of arsenic and cadmium. baxsed on the results of this experiment, it can be generally stated that the presence of arsenic and cadmium in the growing environment of lemongrass causes a decrease in the aerial part and roots of the lemongrass plant. The presence of these two elements also increased the activity of antioxidant enzymes and the accumulation of nutrients in the aerial parts and roots of this plant. These changes continued up to the level of 30 mg / kg of arsenic and cadmium soil.
