“…), a cosmopolitan and submerged aquatic macrophyte genus comprising some species (Lü et al, 2017), is able to accumulate chemicals, as observed in several studies, i.e. in situ accumulation of cobalt, lead, zinc, nickel, iron and manganese in Myriophyllum aquaticum (Harguinteguy et al, 2013(Harguinteguy et al, , 2016 or in Myriophyllum spicatum (Galal and Shehata, 2014). Cu, Cd or arsenic hyperaccumulation in Myriophyllum alterniflorum has also been evaluated from in vitro cultures (Delmail et al, 2011b(Delmail et al, , 2011c2013;Krayem et al, 2016;Krayem et al, 2018).…”

“…Aquatic macrophytes can accumulate and concentrate large amounts of various substances and can act as bio-filters by accumulating heavy metals from the surrounding environment, making them excellent indicators of heavy metal contamination in aquatic ecosystems [6,7]. Peng et al found that the aquatic plants Potamogeton pectinatus had high accumulation capacity for cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), and manganese (Mn) with 596, 318, 62.4, 6590, and 16,000 mg/kg (DW), respectively [8].…”

The Yi River, the second longest river in Shandong Province, China, flows through Linyi City and is fed by three tributary rivers, Beng River, Liuqing River, and Su River in the northeastern part of the city. In this study, we determined the concentrations of five heavy metals (Cr, Ni, Cu, Zn, and Pb) in water, sediment, and aquatic macrophyte samples collected from the junction of the four rivers and evaluated the potential ecological risk of heavy metal pollution. Most of the heavy metals in water were in low concentrations with the water quality index (WQI) below 1, suggesting low metal pollution. The sediments showed low heavy metal concentrations, suggesting a low ecological risk based on the potential ecological risk index (RI) and the geo-accumulation index (Igeo). The aquatic plant species Potamogeton crispus accumulated considerable amounts of heavy metals, which were closely related to the metal concentrations of the sediment. The plant species Salvinia natans also showed an excellent metal accumulation capability. Based on our results, the junction of the four rivers is only slightly polluted in terms of heavy metals, and the plant species P. crispus is a suitable bioindicator for sediment heavy metal pollution.

“…Although the results obtained cannot be applied to field plants, given that the experiments were performed on in vitro watermilfoil cultures, this study will still provide preliminary data of potential use in subsequent in situ studies. Aquatic plants are being envisaged as biological indicators of the ecological state of freshwater (Harguinteguy et al, 2013(Harguinteguy et al, , 2016(Harguinteguy et al, , 2019Decou et al, 2018Decou et al, , 2019 in the same way as fishes, invertebrates or mollusks. As such, this study aims to answer the three following questions: (i) is an enzymatic antioxidant system activated during a sequential burst in response to trace-metal exposure?…”
