Abstract Nanoparticle (NPs) toxicity in the plant has drawn considerable attention. Fenugreek plants were cultivated for 16 days in hydroponic experiments and treated with 50 and 100 mg L− 1 titanium oxide (TiO2) NPs of two sizes [23 ± 1.6 nm (D1) and 83 ± 15 nm. (D2)]. The level of Ti in roots was higher than that of leaves and stems of plants treated with 100 mg L − 1 of TiO2 NPs (D1, D2). Ti caused a depletion of Ca and Mn compared with root control. The titane (Ti) damage to root cellular membranes could alter the plant’s capacity to absorb and transport some nutrients. In our study, increasing the size of TiO2 NPs produced increases in the contents of Mg, Zn and Mn, and a decline in the contents of Fe and Cu in leaves and stems. In roots, Fe and Cu decreased after T iO2 NPs (D2) exposure. Changes in the fenugreek plant mineral composition were assessed, and physiological disturbances could be directly correlated with exposure to NPs. Keywords Nutrients · TiO2 NPs · Trigonella foenum graecum L. · Uptake Nanotechnology is a way to develop and use of materials, structures, devices and systems with innovative properties and functions because of their small size. The ninth most abundant element in the earth’s crust is titanium oxide (TiO2). It has three significant structures: anatase, rutile, and brookite (Ju-Nam and Lead 2008). Dissimilar physicochemical characteristics of TiO2 nanoparticles (NPs) confers on them different bioactivities; these forms have different properties and are used in various environmental applications (Haider et al. 2017; Ismael 2020). Concern over the safety of nanomaterials has been raised due to the impending release of NPs into the environment during the production, use and disposal of NPs-related products (Meng et al. 2009). Nanomaterials have been proven toxic to microorganisms, animals, plants, and humans * Takwa Missaoui [email protected]; [email protected] 1

(Blinova et al. 2010; Dietz and Herth 2011; Shoults-Wilson et al. 2010; Wang et al. 2011; Zhang et al. 2012), impacting on ecological receptors and health (Klaine et al. 2008). Many studies have been performed to understand its environmental contamination and potential bioaccumulation. However, environmental risk assessment requires details beyond the concentrations of NPs and their corresponding toxic actions but also on their environmental behaviour should be evaluated
