To comparatively and simultaneously investigate the reducing efficiency of the different wet-dry alternation cycles on the Cd and As absorption and transportation in rice organs, and synthesis of amino acids (AAs) in rice in two soils with different levels of Cd and As contamination, controlled pot experiments were conducted in this study. Results showed that wet-dry alternation treatments reduced Cd and As concentrations in grains by 18.8%-80% and by 77.4%-86.7% in W soil, respectively; and 76.1%-90.8% and 73.1%-80.6% in H soil, respectively. Cd and As concentrations in the soil solution were negatively and positively correlated with soil pH, respectively; but positively and negatively correlated with soil redox potential (Eh), respectively. The minimum “trade-off” values were observed in the 5 d Flooded followed by 3 d Drained treatment in both soils. The Drained treatment greatly improved AAs contents in rice organs in both soils. The changes of AAs were negatively explained more than 70% by the rachises As. Totally, the F5D3 treatment was identified as the optimal measure for simultaneously minimizing Cd and As accumulations in rice in studied soils, and water management regimes regulated the synthesis of AAs in rice organs by affecting the accumulation of As in rachises.

“…These results were consistent with the outcomes from Deng et al (2020), who observed that Cd translocation in terms of TF straw-husk was higher than TF straw-grain ranging between 0.20-0.24 for TF straw-husk and 0.18-0.20 for TF straw-grain, respectively. Similarly, Khaliq et al (2019) also reported that the TF of Cd in rice grain was much lower as compared to the different parts of the rice plant. The translocation of Cd between different parts of the rice cultivar trended to increase with the increasing Cd level and decrease with increasing Fe concentration.…”

“…The observed value of Cd in rice flour was 20.43 ± 0.84 µg kg −1 , which indicated 91% recovery of the certified value (22.4 ± 0.1.3 µg kg −1 ). The translocation factors (TFs) of Cd from root to straw (TFroot-straw), root to grain (TFroot-grain), straw to husk (TFstraw-husk), and straw to grain (TFstraw-grain) was measured by estimating Cd concentration in one part with respect to the other parts as described by Khaliq et al (2019).…”

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.

“…However, the increase in plant biomass due to the increase of Zn concentration of the plant and consequently the decrease of Cd concentration in the plant cannot be ignored. The competitive effect of Cd and Zn has been mentioned by researchers (41,42). Furthermore, for Cd polluted soil, applying 1.5% (W/W) nano ZnO and 0.5% (W/W) MWCNs significantly increased the plant biomass by 11.1% and 9.8%, respectively.…”

Removal of heavy metals from industrial effluents is one of the most important in environmental research. This research was done to investigate the adsorption effect of multiwall carbon nanotubes (MWNTs) and nano Zn-oxide on decreasing chromium (Cr) and cadmium (Cd) concentration in wheat inoculated with Piriformospora indica (P.indica) that irrigated with wastewater of plating industry. Treatments were consist of applying MWCNs (0 and 0.5 % (W/W)) and nano Zn-oxide (0 and 1.5 % (W/W)) in the soil irrigated with the wastewater of plating industry under wheat inoculated with P.indica. This research was done as a factorial experiment in the layout of completely randomized block design in three replication After 90 days, plants were harvested and plant Cd and Cr were measured using atomic absorption spectroscopy. Using MWCNs had significant effect on increasing cation exchangeable capacity of soil. Applying 0.5 % (W/W) MWCNs in the soil irrigated with waste water significantly decreased the soil Cd concentration by 11.7%, while the plant biomass was increased by 13.4%. In addition, applying 1.5 % (W/W) nano Zn-oxide significantly decreased the negative effect of heavy metal toxicity that can be related to the role of nano Zn-oxide on increasing soil sorption properties. However, the interaction effect of Zn and Cd cannot be ignored. The results of this study showed that applying MWCNs and nano Zn-oxide has a significant effect on decreasing phytoremediation efficiency in soil irrigated with wastewater of plating industries. However, the type and the amount of heavy metals in wastewater cannot be ignored.
