“…Electron microscopy (scanning -SEM and transmission -TEM) and ICP-OES/MS have been widely used due to their capability to determine the size and shape of NPs in plant cells and their high sensitivity, respectively (Kole et al, 2016). For instance, the accumulation of TiO 2 NPs in roots and leaves of rice (Oryza sativa) and their adsorption on the surface of the roots of lettuce were shown by using TEM, SEM, and ICP-OES/MS techniques (Cai et al, 2017;Deng et al, 2017). However, the low resolution of electron microscopy or the complicated sample preparation may bring some difficulties during the analysis (Larue et al, 2014;Tan et al, 2018).…”

“…In literature, there are contradictory reports about the potential toxicity of TiO2-NPs in plants. Some reports proved that it has positive effect (Landa et al, 2012;Singh et al, 2012;Feizi et al, 2013;Song et al, 2013;Servin et al, 2013), some of them mentioned its adverse effects (Asli & Neumann, 2009;Castiglione et al, 2011;Du et al, 2011;Cai et al, 2017) and the others reported even no effect (Zheng et al, 2005;Seeger et al, 2009;García et al, 2011, Larue et al, 2011Landa et al, 2012;Larue et al, 2012;Song et al, 2013;Jacob et al, 2013). Most studies on metallic NPs effects have been done in petri dishes through one week (Dogaroglu & Koleli, 2017a;Dogaroglu & Koleli, 2017b).…”

Titanium dioxide nanoparticles (TiO2-NPs) among metallic NPs are one of the most produced and consumed NPs in the world. Thus, TiO2-NPs release into the environment is inevitable. Their impact on food source cereals is still unclear. The purpose of this study was to assess the phytotoxic impacts of TiO2-NPs on growth and some mineral nutrient (zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), nitrogen (N), phosphorous (P), potassium (K)) uptake of the wheat (Triticum vulgare L.) plant. The TiO2-NP suspensions at increasing concentrations (0, 5, 10, 20 and 40 mg L -1 ) were applied to wheat plant Yunus cultivar grown in hydroponic culture under controlled conditions for 21 days. The results indicate that the TiO2-NPs have not statistically significant effects on plant growth. The chlorophyll content was decreased with increasing TiO2-NP treatment, except for 5 mg L -1 TiO2-NPs treatment. The higher N (4.58%), P (0.78%), Zn (87.50 mg kg -1 ), and Cu (12.90 mg kg -1 ) concentration were recorded at 40 mg L -1 TiO2-NPs treatment. On the other hand, K concentration was decreased at 20 and 40 mg L -1 TiO2-NPs treatments. This study has shown that exposure to TiO2-NPs causes no significant phytotoxic effect on wheat.

“…In addition, TiO 2 NPs and SiNPs have been investigated to support the development of plants by reducing abiotic stress and decreasing uptake of co-contaminants. 7–9 Therefore, in order to identify and evaluate possible risks in food safety, fundamental information is needed regarding the interactions between TiO 2 NPs and plants and robust analytical methods are needed to quantify uptake and translocation of TiO 2 NPs into plants.…”

Understanding the translocation of nanoparticles (NPs) into plants is challenging because qualitative and quantitative methods are still being developed and the comparability of results among different methods is unclear. In this study, uptake of titanium dioxide NPs and larger bulk particles (BPs) at 5 mg/L and 50 mg/L concentrations in rice plant (Oryza sativa L.) tissues was evaluated using three orthogonal techniques: electron microscopy, single-particle inductively coupled plasma mass spectroscopy (spICP-MS) with two different plant digestion approaches, and total elemental analysis using ICP optical emission spectroscopy. In agreement with electron microscopy results, total elemental analysis of plants exposed to TiO2 NPs and BPs at 5 mg/L and 50 mg/L concentrations revealed that TiO2 NPs penetrated into the plant root and resulted in Ti accumulation in above ground tissues at a higher level compared to BPs. spICP-MS analyses revealed that the size distributions of internalized particles differed between the NPs and BPs with the NPs showing a distribution with smaller particles. Acid digestion resulted in higher particle numbers and the detection of a broader range of particle sizes than the enzymatic digestion approach, highlighting the need for development of robust plant digestion procedures for NP analysis. Overall, there was agreement among the three techniques regarding NP and BP penetration into rice plant roots and spICP-MS showed its unique contribution to provide size distribution information.
