“…A decrease in yield and yield components of the rice cultivar through the application of exogenous Cd has been observed by Kanu et al (2017), and the negative consequences were greatly varied depending on the rice cultivar and levels of Cd toxicity in the soil. Reduction of yield and yield-related components due to Cd toxicity was also reported by Herath et al (2014). The application of Fe in the soil increased the number of tillers per hill, plant height, panicle length, number of filled grains per panicle, straw yield, and grain yield of the rice cultivar, and this was more pronounced in Fe1.0 than Fe2.0 compared to the control (Table 4).…”

“…Compared with other cereals, rice (Oryza sativa L.), which is the principal food for more than half of the world's population, is highly efficient in Cd accumulation and transfer from soil to grain (Shahriar et al, 2020). A high concentration of Cd in cultivated land is a serious environmental issue as the toxicity of Cd can pose a threat to food security, impacting both yield and yield components of rice plants (Meharg et al, 2013;Herath et al, 2014). There are several studies reported that Cd toxicity retarded the growth and biomass of rice plants ( Ahsan et al, 2007;Li et al, 2012;Wang et al, 2014).…”

Rice consumption is a major dietary source of Cd and poses a potential threat to human health. The aims of this study were to examine the influence of Fe and Cd application on yield and yield components, dynamics of Cd in pore water, translocation factors, daily dietary intake, and estimation of human health risks. A pot experiment was performed under glasshouse conditions where rice cultivars (Langi and Quest) were cultivated in two dissimilar soils under different levels of Cd (0, 1.0, and 3.0 mg kg−1) and Fe (0, 1.0, and 2.0 g kg−1). The results showed that variation in two rice cultivars in terms of yield and yield-related components was dose dependent. Cadmium concentration in soil pore water was decreased over time and increased with increasing Cd levels but decreased with Fe application. Translocation factors (TFs) from root to straw (TFroot-straw) or straw to husk (TFstraw-husk) were higher than root to grain (TFroot-grain) or straw to grain (TFstraw-grain). The Quest cultivar had 20% lower Cd than the Langi cultivar. Application of Fe at the rate of 1 and 2 g kg−1 soil reduced Cd by 23 and 46%, respectively. Average daily intake (ADI) of Cd exceeded the permissible limit (5.8 × 10−3 mg −1 kg−1 bw per week) when rice plant subjected 1 and 3 mg kg−1 Cd stress with or without Fe application. Results also indicated that ADI value was lower in the Quest cultivar as compared to the Langi cultivar. Estimation of human health risk revealed that the non-carcinogenic risks (HQ > 1) and carcinogenic risks (CR > 1.0 × 10−4) increased with increasing Cd levels in the soil. The application of Fe decreased the human health risks from rice consumption which is more pronounced in Fe 2.0 than in Fe1.0 treatments. The rice cultivar grown in soil-1 (pH 4.6) showed the highest health risks as compared to soil-2 (pH 6.6) and the Quest cultivar had lower health risks than the Langi cultivar.

“…Liu et al (2011) reported that low Cd concentrations could promote plant growth and height of sweet sorghum and experimental sudan grass variety, plant height reached high values at Cd 25 mg/kg while at high concentrations (50 and 100 mg/kg), Cd inhibits the growth of plant height. In other studies in rice, high concentrations of Cd (50 and 100 mg/kg) strongly inhibited the height of the plant (Herath et al, 2014). A study by Liu et al (2014) showed that, after 3 to 7 days of treatment with Cd (25, 50 and 100 mg/kg), the growth of young cotton plants were significantly inhibited, reflecting a sharp drop in height, biomass and leaf area.…”

In recent years, the use of plants for clean-up and recovery (phytoremediation) has been studied and used in many countries of the world. In this study, E-Tian sweet sorghum (ET) and BT x 623 (BT) sorghum were treated with heavy metal cadmium at 5 concentrations (0, 5, 10, 25, 50 mg/kg). The growth of plant; absorption, accumulation of cadmium (Cd) heavy metals in plant parts at the seedling stage have been identified and assessed. The results showed that Cd affected the height and number of leaves of the plant. Especially, Cd accumulation in the plant decreased in sequence: root, stem, leaf. When comparing the heavy metals accumulation in the two cultivars, the results showed that the BT cultivar had higher Cd uptake and accumulation potential than ET. Therefore, BT can be used for phytoremediation of heavy metals in soil but not for providing food and feed.

“…Also, morphological changes occur in response to heavy metals in plants (Brandão et al 2018). But Herath et al (2013) reported variety Bg 352 of rice (Oryza sativa L.) increased the root dry weight from 50 to 100 mg Cd/kg, while Rossato et al (2012) reported the no alteration in the dry weight yield of Pluchea sagittalis Lam. plant organs after heavy metal exposure might be connected with synthesis of cell wall polysaccharides.…”

Potential of Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. for phytoremediation of Cd-contaminated soil

et al. 2019

In three-pot experiments, the uptake and translocation potential of cadmium (Cd) by Mentha aquatica L., Eryngium caucasicum Trautv. and Froriepia subpinnata Ledeb. was evaluated in different Cd concentrations including 0 (control), 5, 10, 15 and 20 mg Cd kg-1 dried soil. Plants accumulated Cd in their roots and shoots without toxicity symptoms. Enhancement of Cd concentration greatly decreased plant biomass. Bioconcentration factor (BCF) and translocation factor (TF) in F. subpinnata were higher than one that indicated higher efficiency of this plant for phytoextraction of Cd from soil. The efficiency of plants in uptake and translocation of Cd depends on species, biomass production, Cd concentration in biomass and soil. Cadmium concentration in M. aquatica root was higher than shoot. Mentha aquatica with higher BCF and lower TF than one can be suitable for phytostabilization of Cd. Also, uptake index and BCF for M. aquatica showed better phytoremediation potential in comparison with E. caucasicum and F. subpinnata.
