“…Dry biomass of E. crassipes increased over 30 days, with higher absorbance of Cr and Cu 2+ in roots compared to leaves (Tabinda et al . 2018), similar to our results, and that TF is significantly influenced by increasing Cu 2+ concentration (Figure S1, Table S1), while the BCF of the stem and leaf was remarkably lower than that of the root (Table S1). The difference in BCF provide an important mechanism to protect aboveground plant parts from heavy metal stress by accumulating heavy metals in the roots, as also found by Pereira et al .…”

Effect of copper on the photosynthesis and growth of Eichhornia crassipes

et al. 2021

Although copper is essential for plant growth and development and plays an important role in many physiological processes, excess copper, resulting from industrial development and population expansion in the recent decades, leads to environmental pollution and has been a cause of wide concern for the adverse effects on photosynthesis, metabolism and growth of plants. The growth properties (e.g. fresh weight, root length, height), photosynthetic properties (e.g. gas exchange, chlorophyll a fluorescence, chlorophyll content) and the physiological index (e.g. activity of antioxidant enzymes and osmotic regulators) of Eichhornia crassipes were assessed under various Cu2+ concentrations in hydroponic experiments. The growth of E. crassipes was negatively affected by Cu2+ treatments, especially at higher Cu2+ concentrations; the Cu2+ treatments resulted in decreased photosynthesis because of a decrease in leaf chlorophyll content and damage to PSII functions, except the oxygen‐evolving complex. The physiological tolerance of E. crassipes to Cu2+ relies on osmotic regulation, anti‐lipid peroxidation and improved antioxidant properties. The results indicate that E. crassipes could be considered as a phytoremediation agent for Cu2+ pollution in aquatic environments. However, the benefit of E. crassipes for Cu2+ removal in a highly polluted aquatic environment will be limited, but it will be effective in remediating sites with low pollution (≤5 mg·l−1). The present results could provide not only a basis for understanding the effects of pollutants on photosynthesis in plants under heavy metal stress but also provide a basis for choosing plants for phytoremediation.

“…For instance, Cu 2+ can be removed using E. crassipes for phytoremediation (Tabinda et al . 2018), and in this way, Cu 2+ could be eliminated from the aqueous environment and converted into a less toxic form by chelation with natural ligands released from the plant tissues (Abdelraheem et al . 2016, 2017).…”

“…A study found that the common water hyacinth Eichhornia crassipes has efficient Cr removal capability, where they conducted a small-scale hydroponic experiment with different metal concentrations for one month period. The accumulation of Cr was significantly higher in the roots compared to shoot [129]. Cirsium vulgare plant is an effective accumulator for Cr and can be effectively used for the phytoremediation of the Cr-contaminated soils [130].…”

Chromium Stress in Plants: Toxicity, Tolerance and Phytoremediation

et al. 2021

Extensive industrial activities resulted in an increase in chromium (Cr) contamination in the environment. The toxicity of Cr severely affects plant growth and development. Cr is also recognized as a human carcinogen that enters the human body via inhalation or by consuming Cr-contaminated food products. Taking consideration of Cr enrichment in the environment and its toxic effects, US Environmental Protection Agency and Agency for Toxic Substances and Disease Registry listed Cr as a priority pollutant. In nature, Cr exists in various valence states, including Cr(III) and Cr(VI). Cr(VI) is the most toxic and persistent form in soil. Plants uptake Cr through various transporters such as phosphate and sulfate transporters. Cr exerts its effect by generating reactive oxygen species (ROS) and hampering various metabolic and physiological pathways. Studies on genetic and transcriptional regulation of plants have shown the various detoxification genes get up-regulated and confer tolerance in plants under Cr stress. In recent years, the ability of the plant to withstand Cr toxicity by accumulating Cr inside the plant has been recognized as one of the promising bioremediation methods for the Cr contaminated region. This review summarized the Cr occurrence and toxicity in plants, role of detoxification genes in Cr stress response, and various plants utilized for phytoremediation in Cr-contaminated regions.

“…They therefore represent a valuable tool for the assessment of PTE concentrations within macrophytes. Although P. stratiotes has been the subject of considerable recent phytoremediation research [28,[30][31][32][33][34][35][36][37], there is a dearth of published prediction models for PTE uptake within the shoot and root systems of P. stratiotes growing in natural environments. Mathematical models describing PTE uptake by P. stratiotes grown on paper mill effluent in a lab scale phytoremediation experiment were developed by Kumar et al [10]; however, these models cannot be used to predict PTE uptake in conditions other than those used in the experiment.…”

Uptake Prediction of Eight Potentially Toxic Elements by Pistia stratiotes L. Grown in the Al-Sero Drain (South Nile Delta, Egypt): A Biomonitoring Approach

et al. 2021

The potential to utilise the free-floating macrophyte Pistia stratiotes L. to survey contamination of the Al-Sero Drain in the South Nile Delta, Egypt, by eight potentially toxic elements (PTEs) was investigated in this study. This study considered the absorption of eight PTEs (Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn), and the evaluated P. stratiotes were located in three sampling locations along the Al-Sero Drain, with sampling conducted in both monospecific and homogenous P. stratiotes. Samples of both types of P. stratiotes and water were collected on a monthly basis between May 2013 and April 2014 at each location, utilising three randomly chosen 0.5 × 0.5 m quadrats. Regression models were designed to predict the concentration of the PTEs within the plant’s shoot and root systems. Elevated water Fe levels were correlated with a rise in shoot system Fe concentration, whereas higher Ni concentrations in the water led to a higher Ni concentration within the root system. The latter was also true for Pb. Water Cu levels had a negative association with the Cu concentration within the P. stratiotes shoot system. Raised Fe levels were also correlated with a diminished Fe level within the roots. For all PTEs, P. stratiotes was characterised by a bioconcentration factor of more than 1.0, and for the majority by a translocation factor of less than 1.0. The goodness of fit for most of the designed models, as indicated by high R2 values and low mean averaged errors, demonstrated the associations between actual and predicted PTE concentrations. Any disparity between measured and predicted parameters failed to reach significance with Student t-tests, reinforcing the predictive abilities of the designed models. Thus, these novel models have potential value for the prediction of PTE uptake by P. stratiotes macrophytes inhabiting the Al-Sero Drain. Furthermore, the macrophyte’s constituents indicate the long-term impact of water contamination; this supports the potential future use of P. stratiotes for biomonitoring the majority of the PTEs evaluated in this study.
