The concentrations of heavy metals in water, sediments, and aquatic organisms, including aquatic plants, needs to be estimated and analyzed, because metals can continuously move from one trophic level to another. The present study aimed to evaluate the contamination of the two aquatic plants of Typha domingensis and Potamogeton pectinatus in the Al-Shamiyah River in Al-Diwaniyah, Iraq, with heavy metals of copper, manganese, cadmium, lead, zinc, and chromium. The concentrations of heavy metals in T. domingensis were as follows: Cu: 24.56-76.40, Mn: 174.47-642.97, Cd: 0.70-23.58, Pb: 1.84-127.75, Zn:  2.70-150.14, and Cr: 1.34-35.26 ?g/g dry weight. The concentrations of these metals in P. pectinatus were as follows: Cu: 16.59-348.72, Mn: 299.74-642.84, Cd: 1.51-34.75, Pb: 1.72-30.44, Zn: 30.57-152.59, and Cr: 1.15-34.99 ?g/g dry weight. The results highlight the role of these two large aquatic plants as monitoring tools for heavy metals pollution as well as the rehabilitation of the aquatic habitats.
