“…Parsons et al (2010) reported that exposure mesquite plants to Ni(OH) 2 MNMs had no effect on biomass production, shoot elongation, or root elongation. Navarro et al (2012) found that Arabidopsis plants produced reduced glutathione relative to oxidized glutathione after exposure to CdSe/ZnS quantum dots, indicating that the MNMs induced oxidative stress in the plants.…”

“…This is often an interaction between the plants and the mycorrhizal fungi. Furthermore ENMs may adsorb strongly to the roots thus exerting effects even without being actually taken up as particle (Navarro et al, 2012). However, it should be noted that most information on this adsorption is drawn from hydroponic exposures and the mobility of ENM in water may be much larger Downloaded by [Karolinska Institutet, University Library] at 05:00 18 November 2014 in comparison to soil.…”

Interactions within natural soils have often been neglected when assessing fate and bioavailability of engineered nanomaterials (ENM) in soils. This review combines patchwise ENM research using natural soils with the much wider literature on ENM performed in standard tests or on the fate of colloids in soils, and an analysis of the diverse ENM characteristics determining availability from the soil organisms' perspective to assess the main soil characteristics that determine the fate, speciation, and ultimately bioavailability of ENM in natural soils. Predominantly salinity, texture, pH, concentration, and nature of mobile organic compounds and degree of saturation determine ENM bioavailability.

“…More recently, Waalewijn-Kool et al (2013) showed that Zn concentration in pure water increased with time for all ZnO forms but peaked at intermediate concentrations for uncoated ZnO-NP and non-nano ZnO, while for coated ZnO-NP this dominant peak was only seen after 12 months. Navarro et al (2012) reported that HAs enhance the accumulation of CdSe/ZnS NPs onto the root surface of Arabidopsis thaliana. However, the mechanism is not clear and needs to be further studied.…”

Zinc oxide-engineered nanoparticles (ZnO ENPs) have received the most attention in recent years. This increasing interest has been directed towards studying the environmental fate and effects of ZnO ENPs on ecological terrestrial species. In this study, ZnO NPs were synthesized by atmospheric pressure solution evaporation method and were coated or uncoated with humic acid (HA). The root uptakes of uncoated and HAcoated ZnO NPs and zinc (Zn) were investigated by gel-grown cucumber. Two ZnO levels (1 and 200 µM) were applied in the form of coated (T 3 ) and non-coated (T 2 ) NPs or bulk particles (T 1 ). The results showed that coating NPs by HA increases zeta potential of NPs and decreases their aggregation size due to the increase in the repulsion forces among the particles. Addition of 1 mgL −1 ZnO into gel chamber enhanced root and shoot biomass; however, the shoot growth was higher in the presence of NPs compared to its bulk counterpart. Moreover, greater phytotoxicity of ZnO from the source of NPs than bulk particles in shoot was observed. Scanning electron microscopy results showed a clear evidence of the penetration of NPs into root cells. ARTICLE HISTORY
