Water management impacts on the solubility of Cd, Pb, …

Iron plaque can act as a filter to prevent the ions from moving into plant roots by adsorption and/or co-precipitation. It may also act as a pool for ion accumulation in plants (Li et al., 2016; Zhong et al., 2010; Zhou et al., 2015). The role of iron plaque in ion accumulation depends on the amount of Fe, ionic species, and plant species.
