The potential bioaccumulation of hazardous transitional heavy metals in components of the aquatic environment (such as water column, sedimentary matter, plants) constitutes one of the concerns in environmental protection engineering. This experimental investigative study used systematic measurements of the presence of selected heavy metals (cadmium, chromium, copper, lead, nickel and zinc) in components of the aquatic environment to give an indication of their availability and their potential bioaccumulation in the perennial wetland plants. Through environmental quality data processing, this study allowed both the assessment of interphase partitioning constants of these metals throughout the analyzed aquatic environment and the estimation of their cumulative toxicity coëfficiënt. The data analysis highlighted the different potential degrees of dangers caused by metals as pollutants and the synergistic way in which they act on the aquatic environment.
