“…Leveraging advanced spectroscopic and microscopic capabilities such as X-ray absorption spectroscopy (XAS), scanning/ transmission electron microscopy-energy dispersive spectroscopy (S/TEM-EDS), confocal laser scanning microscopy (CLSM), and other similar instrumentations, novel evidences are increasingly being presented of alternative uptake into plant tissues of Fe, Cu, Mn, Ni, Mo, and Zn in the form of oxides or composite particles (Aubert et al 2012;Dimkpa et al 2012bDimkpa et al , 2013aWang et al 2012a, b;Faisal et al 2013;Ghafariyan et al 2013;Pradhan et al 2013;Bandyopadhyay et al 2015). This is in contrast to the conventional uptake of micronutrients as ions, hitherto the consensus knowledge.…”

“…However, endocytosis has been evinced as a possible strategy for plant uptake of particulate elements, based on (i) the findings that an inhibitor of plant cell endocytosis resulted in reduced uptake of carbon nanotubes and also (ii) the demonstration that the uptake of intact CuO particles occurs in cells that show the presence of endosomes (Liu et al 2009;Nair et al 2010;Wang et al 2012a, b). Notably, the presence of nutrient NPs in shoots has been demonstrated from both root (Zhu et al 2008;Dimkpa et al 2012bDimkpa et al , 2013aWang et al 2012a, b;Ghafariyan et al 2013;Bandyopadhyay et al 2015) and foliar (Wang et al 2013a, b) applications in wheat, watermelon (Citrullus lanatus), corn, alfalfa, pumpkin (C. pepo), and soybean, among other crops. Regardless of the application route, the presence of micronutrient particles could be residual enough to allow transportation from point source to distal plant parts (Wang et al 2012a(Wang et al , b, 2013a, or they could dissolve in planta, sometime after uptake, releasing the cognate metal ions for plant metabolism.…”

“…Thus, we argue that while each NP has to be examined on its own merit for its effects in different plantsoil systems, in general, the exposure dose and environmental chemistry may be more important in making the "poison" than the "nano" nature of the NP. Indeed, the risks from NPs appear to be either less potent, or no more potent, than risks provoked by salt micronutrients at similar application doses (Kim et al 2014;Kouhi et al 2014;Bandyopadhyay et al 2015). In any case, the judicious use of micronutrients, irrespective of the form in which they are packaged, is important for maximizing benefits while minimizing risks.…”

Micronutrients are essential mineral elements required for both plant and human development. However, micronutrients are often lacking in soils, crop, and food. Micronutrients are therefore used as fertilizer to increase crop productivity, especially when the application of conventional NPK fertilizers is not efficient. Here, we review the application of micronutrients in crop production. Reports show that micronutrients enhance crop nutritional quality, crop yield, biomass production, and resiliency to drought, pest, and diseases. These positive effects range from 10 to 70 %, dependent on the micronutrient, and occur with or without NPK fertilization. We discuss the uptake by plants of micronutrients as nanosize particulate materials, relative to conventional uptake of ionic nutrients. We also show that packaging of micronutrients as nanoparticles could have more profound effects on crop responses and fertilizer use efficiency, compared to conventional salts or bulk oxides.

Although the use of engineered nanomaterials continues to increase, how these materials interact with coexisting contaminants in the environment is largely unknown. The effect of silver (Ag) in bulk, ionic, and nanoparticle (NP; bare and polyvinyl pyrrolidone-coated) forms at 3 concentrations (0 mg/kg, 500 mg/kg, 1000 mg/kg, 2000 mg/kg; ion at 69 mg/kg, 138 mg/kg, 276 mg/kg) on the accumulation of field-weathered chlordane and dichlorodiphenyldichloroethylene + metabolites (DDX) by Eisenia fetida (earthworm) was investigated. Earthworm biomass and survival were unaffected by treatment. At the 500 mg/kg and 1000 mg/kg exposure levels, NP-exposed earthworms contained significantly greater Ag (194-245%) than did the bulk exposed organisms; NP size or coating had no impact on element content. Generally, exposure to Ag of any type or at any concentration significantly reduced pesticide accumulation, although reductions for DDX (35.1%; 8.9-47.0%) were more modest than those for chlordane (79.0%; 17.4-92.9%). For DDX, the reduction in pesticide accumulation was not significantly affected by Ag type or concentration. For chlordane, the 3 NP exposures suppressed chlordane accumulation significantly more than did bulk exposure; earthworms exposed to bulk Ag contained 1170 ng/g chlordane, but levels in the NP-exposed earthworms were 279 ng/g. At the 500 mg/kg exposure, the smallest coated NPs exerted the greatest suppression in chlordane accumulation; at the 2 higher concentrations, chlordane uptake was unaffected by NP size or coating. The findings show that in exposed earthworms Ag particle size does significantly impact accumulation of the element itself, as well as that of coexisting weathered pesticides. The implications of these findings with regard to NP exposure and risk are unknown but are the topic of current investigation. Environ Toxicol Chem 2017;36:1864-1871. © 2016 SETAC.
