Fate of Fe₃O₄@NH₂ in soil and their fixation effect to reduce lead translocation in two rice cultivars.

ABSTRACT: The fate of nanoparticles in the ecological chain of agriculture has been concerned as their potential pollution and biological effect to humans with rapid development and massive emission of nanomaterials. Here, we found that two rice cultivars (Oryza sativa L) have different heavy metal accumulation results in the roots and shoots after 15 days growth. Two rice cultivars (Oryza sativa L), grown in soil containing magnetite (Fe₃O₄@NH₂) nanoparticles and heavy metal simultaneous, showed less Pb uptake in the roots and shoots, compared with that without Fe₃O₄@NH₂ added. The shape and magnetic properties of Fe₃O₄@NH₂ have no obvious change; however, the transmission electron micro
