“…A similar pattern was observed in Cd concentrations of roots, shoots and leaves, and Zn concentrations of shoots and leaves ( Table 2). The results are consistent with previous studies [29]. Compared to heavy metals-contaminated soil without amendment, the application of natural palygorskite (PAL) or its modified form (KH550-PAL) significantly reduced the bio-concentration factor of heavy metals in tomato (Table 2).…”

A field experiment was conducted to investigate differential effects of natural palygorskite (PAL) and its modified form (KH550-PAL) on the alleviation of heavy metals toxicity to tomatos grown in contaminated soil with Cd, Pb and Zn. Compared to heavy metal-contaminated soil without amendment, the application of natural palygorskite (PAL) or its modified form (KH550-PAL) significantly alleviated heavy metal toxicity to tomato. In addition, foliar malondialdehyde (MDA), hydrogen peroxide (H 2 O 2) and superoxide (O 2 •-) contents as well as non-photochemical quenching (NPQ) reduced by 89, 28, 71, and 81%, respectively, in the modified palygorskite treatment than in the natural palygorskite treatment. Similar patterns were observed in heavy metals uptake of tomato. Foliar superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR) activities increased by 228, 196 and 238%, respectively, in the modified palygorskite treatment than in the natural palygorskite treatment. Thus, the application of the modified form (KH550-PAL) significantly ameliorated the oxidative stress via enhancing antioxidant defense and reducing thermal dissipation, which further improved photosynthetic electron transport of photosystem II and biomass accumulation of tomato. However, the dose of the modified palygorskite (KH550-PAL) was not enough to buffer negative effects of heavy metal toxicity to tomato growth in the experiment. It is suggested that the amendment dose should be used with great care in remediating contaminated soils with heavy metals. Thus, further experiments are needed by different rates of the modified palygorskite (KH550-PAL).

“…The BN 5%, FeHP 2% and CM 0.5% treatments showed the least BCF values of Pb, compared to the control. These lower BCF values of Pb indicate a very low transfer of Pb in pea showing its least bioavailability in the BN 5%, FeHP 2% and CM 0.5% amended soil, compared to control treatment [21].…”

Lead (Pb)-polluted soils pose a serious threat to human health, particularly by transmitting this heavy metal to the food chain via the crops grown on them. The application of novel amendments in Pb-polluted soils can significantly reduce this problem. In this research, we report the effects of various organic and inorganic amendments i.e., bentonite (BN), biochar (BR), lignin (LN), magnesium potassium phosphate cement (CM) and iron hydroxyl phosphate (FeHP), on the Pb bioavailability in Pb-polluted soil, upon Pb distribution in shoots, roots, grain, the translocation factor (TF) and the bioconcentration factor (BCF) of Pb in pea (Pisum sativum L.) grain. Furthermore, effects of the said amendments on the plant parameters, as well as grain biochemistry and nutritional quality, were also assessed. Lead pollution significantly elevated Pb concentrations in roots, shoots and grain, as well as the grain TF and BCF of Pb, while reducing the nutritional quality and biochemistry of grain, plant height, relative water content (RWC), chlorophyll contents (chl a and chl b) and the dry weight (DW) of shoot, root and grain. The lowest Pb distribution in shoots, roots and grain were found with BN, FeHP and CM, compared to our control. Likewise, the BN, FeHP and CM significantly lowered the TF and BCF values of Pb in the order FeHP > CM > BN. Similarly, the highest increase in plant height, shoot, root and grain DW, RWC, chl a and chl b contents, grain biochemistry and the micronutrient concentrations, were recorded with BR amendment. Biochar also reduced grain polyphenols as well as plant oxidative stress. Given that the BR and BN amendments gave the best results, we propose to explore their potential synergistic effect to reduce Pb toxicity by using them together in future research.

“…Irrespective of compost treatments and phosphate sources, increasing phosphate levels significantly decreased shoots and roots Cd content (Zhao et al.,2014). Guo, et al, (2018 ) reported that P amendments help to reduce Cd phytotoxicity to crop plants by limiting its availability in the soil through the formation of mixed metal phosphates , which could have restricted Cd uptake by plants.…”

“…The obtained results are in accordance with the results of Zhu et al (2004) they reported that the pb concentrations in both shoots and roots of two vegetable plants decreased with increasing quantities of added P compound. Guo, et al (2018) reported that plant-tissue concentration of Pb was consistently reduced in the presence of phosphorus, possibly through the formation of mixed metal phosphates , which could have restricted Pb uptake by plants.…”

“…As an alternative technique, in situ metal immobilization using soil amendments has been promoted as a immediate, cost-effective, and low disruption technique (Keller et al, 2005;Lee et al, 2009). There are a lot of amendments, such as organic amendments (Beesley et al, 2014 ;Karer et al, 2015) and phosphate minerals (Guo, et al, 2018) have been developed for minimize the availability of heavy metals in soils. These technologies may induce adverse effects on soil health and food safety (Chuan-chuan et al, 2016).…”

A pot experiment with maize (single cross-2030) was conducted to study the influence of phosphorus sources and levels and compost additions on growth, cadmium (Cd) and lead (Pb) contents of maize, as well as the availability of cadmium and lead in rhizosphere soil after the harvest of maize plants in three contaminated soils. It was observed in the three soils used in this study that compost addition increased significantly shoots and roots dry weight of maize plants and performed better than phosphate. With the three soils used in the study, results indicated that plants grown in soils amended with compost and supplied with rock phosphate (RP) at the high phosphate level, recorded the highest shoots & roots dry weight. Cadmium & lead contents of the both shoots & roots of maize plants were significantly reduced as a result of compost treatment. Rock phosphate addition significantly reduced Cd and Pb contents of both shoots and roots compared to single supper phosphate (SSP) for all soils examined. Increasing phosphate levels markedly reduced Cd and Pb contents of both shoots and roots with all soils studied. Also, the results revealed that plants grown in soils amended with compost and supplied with RP at high phosphate level recorded the lowest cadmium and lead contents of shoots and roots for the three soils used in this study. The availability of cadmium and lead in rhizosphere area after the harvest of maize plants were significantly decreased in all soils studied as a result of compost treatments. RP treatments significantly decreased the availability Cd and Pb in rhizosphere area of all soils studied compared to SSP addition. The available Cd and Pb in rhizosphere area were reduced as a result of increasing phosphate levels. The lowest value of available cadmium and lead in rhizosphere area of all studied soils were recorded for soils amended with compost and treated with RP at the high phosphate level.
