In aquatic ecosystems, aquatic plants are good biochemical indicators for monitoring heavy metals because they are stagnant in water and can determine contamination levels. This research was conducted in 2018 to investigate heavy metals of cadmium, nickel and vanadium in aquatic plants of straw (Phragmites australis) and Louisiana (Typha latifolia) of Horralzim wetland in Khuzestan province. Sampling was performed from three stations. In order to measure heavy elements was used to measure the induction plasma (ICP). The highest of cadmium in root of Phragmites australis was 1.486±0.020 mg Kg-1 and lowest concentration of this metal in stem of Typha latifolia was 0.036±0.001 mg Kg-1 (P<0.05). The highest of nickel in root of Typha latifolia was 4.770±0.045 mg Kg-1 and lowest concentration of nickel in stem of Phragmites australis was 0.843±0.072 mg Kg-1 (P<0.05). The highest of vanadium in root of Typha latifolia was 16.553±0.128 mg Kg-1 and lowest concentration of vanadium in stem of Phragmites australis was 3.136±0.015 mg Kg-1 (P<0.05).The concentrations of cadmium, nickel and vanadium were obtained in the root of Phragmites australis and Typha latifolia above the leaves and stems (P<0.05). Cadmium in the roots, stems and leaves of the Phragmites australis was higher than the Typha latifolia, but the amount of nickel and vanadium in the roots, stems and leaves of Typha latifolia were higher than Phragmites australis (P<0.05).
