Background and aims Iron plaque can affect the absorption and accumulation of metal(loid)s in plants. However, it is still unclear whether iron plaque plays different roles in the accumulation of different mercury species in rice plants. The aims of this study are 1) to explore the adsorption of IHg and MeHg onto iron plaque, 2) to investigate the influence of iron plaque on the absorption, translocation of IHg and MeHg in rice plants, 3) to explore whether the process of methylation and demethylation of Hg in vivo occurs in rice plants, and 4) to investigate the effects of iron plaque on the IHg and MeHg transformation in rice.
