1. Introduction. Due to the rapid development of industrial and agricultural activities, heavy metals have been widely detected in the soil (Liu et al., 2020b).Owing to the persistence, high toxicity, and non-biodegradability, heavy metal contaminated soil has been considered as an increasingly severe environmental problem (Liu et al., 2018b).Cd, …

Pb and Cd were selected because they are known to be toxic, while Cu and Zn are essential nutrient for plants (Abbasi et al., 2020). The metabolomic combined with rhizospheric soil microorganism analysis were adopted to expound the effects of MNPs on absorption and translocation of Cu, Zn, Pb and Cd by lettuces.

Reduced plant growth caused by Pb stress is a restriction factor limiting Pb uptake by hyperaccumulator plants grown on contaminated lands. Moreover, the Pb solubility and hence bioavailability is usually low in contaminated alkaline soils, limiting the phytoextraction efficiency in these soils (Fig. 10.1).Therefore, any treatment enhancing …

As expected, the presence of bacteria resulted in increased concentrations of water-extractable Cu, Zn, Pb, Cd, and Fe in autoclaved soil compared to axenic soil (Figure 2). These results suggest that the 10 Cu/Zn-resistant isolates had metal-solubilizing potential in heavy metal-polluted soil, thereby increasing metal bioavailability.
