“…The same factor was calculated by different researchers and denoted as the "shoot" part using different terms such as "aerial part" [39,51,62,98], stem [54,59,100,147], aboveground tissue part [50,56], and leaves [62,100,148]. Similarly, in the case of ferns, the term "frond" [65,97] and "cap" in case of mushroom [149] were also used to denote the shoot part.…”

This paper reviews research on phytoremediation (2002–2021), particularly for the estimation of plant efficiency and soil pollution indices, examining the extraction of metals from soil and plants growing under both artificial (spiked with specific metal) and natural conditions. From the analysis of >200 published experimental results, it was found that contamination factor and geo-accumulation index as well as translocation and bioconcentration factors are the most important soil pollution and plant efficiency metrices, respectively, which are gaining importance to assess the level of metal pollution and its transfer from soil to plant to find a better metal clean-up strategy for phytoremediation. To access the metal concentration, it was found that the most widely accepted extractants to dissolve and extract the metals from the soil and plant were HNO3 and HClO4 (mainly in 5:1; v/v or 4:1; v/v), which are used both in natural and artificial metal contamination studies. Moreover, plants such as Pteris vittata, Monochoria korsakowi, Lolium perenne, Festuca rubra, Poa pratensis, Ricinus communis, and Siegesbeckia orientalis can act as hyperaccumulators under both natural and artificial experiments and can be directly implemented into the fields without checking their further efficiency in phytoremediation.

“…Previous studies have shown that this plant could effectively remove total nitrogen and phosphorus in eutrophic water, and meanwhile maintain a good physiological condition (Fu et al 2013;Li et al 2016). Meanwhile, M. korsakowii could immobilize most lead in the root system, and enhance the tolerance of leaf cells to lead stress by improving SOD, CAT, and total antioxidant activity (Kim et al 2009). To clarify the tolerance and related resistance mechanism of M. korsakowii photosynthesis under heavy metal stress and explore its application potential in heavy-metal contaminated water phytoremediation, a hydroponic experiment was used to investigate variations in photosynthetic physiological parameters, chlorophyll fluorescence characteristics, and antioxidant enzyme activities in leaves of M. korsakowii exposed to 0.05, 0.10, 0.15, 0.30, and 0.45 mM Cd 2þ concentration for 7 d. The distribution characteristics of Cd 2þ in the roots, stems, and leaves of M. korsakowii were also investigated.…”

To identify the tolerance mechanisms of wetland plants exposed to heavy metal, a hydroponic experiment was used to investigate variations in photosynthetically physiological parameters and antioxidant enzyme activities in leaves of Monochoria korsakowii exposed to 0.05, 0.10, 0.15, 0.30, and 0.45 mM Cd2+ for 7 d. The Cd2+ concentrations in the plant roots, stems, and leaves were also investigated. Cd2+ exposure significantly decreased the total chlorophyll content, net photosynthetic rate, intercellular carbon dioxide concentration, and stomatal conductance, while stomatal limitation value had the opposite trend (P < 0.05). During Cd2+ stress, ascorbate peroxidase activity significantly increased (P < 0.05). The translocation factor for Cd2+ was significantly lower than that of the control, and both were less than 1 (P < 0.05). Cd2+ stress damaged the photosynthetic apparatus in the leaves. During Cd2+ stress, M. korsakowii alleviated oxidative stress by increasing the activities of antioxidant enzymes, such as APX. Under 0.45 mM Cd2+ stress, increased heat dissipation was responsible for alleviating the photooxidative damage to photosynthetic organs in the leaves. Meanwhile, the majority of Cd2+ was immobilized in the roots, thus alleviating excessive Cd2+ phytotoxicity in aboveground parts. Generally, M. korsakowii has potential application in the phytoremediation of low-cadmium-polluted water. HIGHLIGHTS Ascorbate peroxidase plays a significant role in alleviating oxidative stress in the leaves. Cadmium immobilized in roots accounted for the plant tolerance to cadmium exposure. M. korsakowii has potential application in phytopremediation of low-cadmium polluted water.
