Interaction of nanoparticles with edible plants and their possible implications in the food chain.
TLDR
The uptake, bioaccumulation, biotransformation, and risks of nanomaterials (NMs) for food crops are still not well understood and the possible biomagnification of NPs in the food chain is unknown. Expand
The biochemistry of environmental heavy metal uptake by plants: implications for the food chain.
TLDR
This review focuses on plant uptake of the toxic elements arsenic, cadmium, chromium, mercury, and lead and their possible transfer to the food chain. Expand
Enhancement of lead uptake by alfalfa (Medicago sativa) using EDTA and a plant growth promoter.
TLDR
The results of a study on the combined effects of ethylenediaminetetraacetic acid (EDTA) and the phytohormone indole-3-acetic Acid (IAA) on Pb uptake by Medicago sativa indicate that non-metal hyperaccumulator plants could increase theirhyperaccumulating potential without genetic manipulation.

TLDR
Juxtaposed against widespread land application of wastewater treatment biosolids to food crops, these findings forewarn of agriculturally associated human and environmental risks from the accelerating use of MNMs. Expand
Effect of cerium oxide nanoparticles on rice: a study involving the antioxidant defense system and in vivo fluorescence imaging.
TLDR
Findings demonstrate a nCeO2 concentration-dependent modification of oxidative stress and antioxidant defense system in rice seedlings. Expand
Uptake and reduction of Cr(VI) to Cr(III) by mesquite (Prosopis spp.): chromate-plant interaction in hydroponics and solid media studied using XAS.
TLDR
Experiments are currently being performed to evaluate the behavior of the Mesquite plant using lower Cr concentrations, and used X-ray absorption spectroscopy to determine the mechanisms involved in the uptake and binding of Cr(VI) in live mesquite tissue. Expand
Evidence of the differential biotransformation and genotoxicity of ZnO and CeO2 nanoparticles on soybean (Glycine max) plants.
TLDR
Although the NPs did not affect soybean germination, they produced a differential effect on plant growth and element uptake, and genotoxic effects from the exposure of soybean plants to CeO(2) NPs were demonstrated. Expand
Synthesis of plant-mediated gold nanoparticles and catalytic role of biomatrix-embedded nanomaterials.
TLDR
Growth of Sesbania seedlings in chloroaurate solution resulted in the accumulation of gold with the formation of stable gold nanoparticles in plant tissues, and the catalytic function of the nanoparticle-rich biomass was substantiated by the reduction of aqueous 4-nitrophenol (4-NP). Expand
Nanomaterials and the environment: a review for the biennium 2008-2010.
TLDR
A review of publications on nanomaterials in the biennium 2008-2010 includes the most recent publications in risk assessment/toxicity, characterization and stability, toxicity, fate and transport of NMs in terrestrial ecosystems, and new ENMs. Expand
