“…Other metallic nanoparticles, such as titanium and zinc nanoparticles, have been found to affect the soil microbiota, depending on the concentration and the duration of exposure [125,126]. Apart from the intrinsic properties (chemical nature, size, coating) and concentration, the impact of nanoparticles on plant root and rhizosphere microbiota are largely dependent on soil texture, pH, organic matter content, and fertilization [127][128][129].…”

Our agriculture is threatened by climate change and the depletion of resources and biodiversity. A new agriculture revolution is needed in order to increase the production of crops and ensure the quality and safety of food, in a sustainable way. Nanotechnology can contribute to the sustainability of agriculture. Seed nano-priming is an efficient process that can change seed metabolism and signaling pathways, affecting not only germination and seedling establishment but also the entire plant lifecycle. Studies have shown various benefits of using seed nano-priming, such as improved plant growth and development, increased productivity, and a better nutritional quality of food. Nano-priming modulates biochemical pathways and the balance between reactive oxygen species and plant growth hormones, resulting in the promotion of stress and diseases resistance outcoming in the reduction of pesticides and fertilizers. The present review provides an overview of advances in the field, showing the challenges and possibilities concerning the use of nanotechnology in seed nano-priming, as a contribution to sustainable agricultural practices.

“…The morphology of TiO 2 NP was characterized using Transmission electron microscopy (TEM) (JEOL 1010, IEOL Ltd., Japan), and the hydrodynamic size distribution was measured using dynamic light scattering (DLS) (Malvern, Instruments Ltd., UK). The physico-chemical properties of TiO 2 NPs were characterized in our previous study (Zhai et al, 2019a) and given in Fig. S1.…”

“…The same amount of sterilized water without TiO 2 NPs was added into the control soils. Soil microcosms were incubated at 20 °C for 15 and 60 day representing shortand long-term exposure (Zhai et al, 2019a). In total 48 microcosms with triplicate per treatment were prepared (4 soils × 2 concentrations of TiO 2 NPs (i.e.…”

“…However, in the long term (60 days), these adverse effects at low concentration disappeared, reporting an increase in the abundance of taxa according to the increase in exposure dose (500 and 2000 mg kg −1 ). Concerning the functionality of the community, the enzymatic activity did not change significantly (60 days), which suggests that the dehydrogenase activity promoted the tolerance of microorganisms in the presence of TiO 2 -ENPs (Zhai et al, 2019 ). The effects of ZnO- and CuO-ENMs (10 mg kg −1 ) on soil microbial community in different soil types were witnessed by the dehydrogenated activity, which was affected by the presence of Cu after 90 days of incubation (Josko et al, 2019 ).…”

Graphical abstract Currently, hundreds of different nanomaterials with a broad application in products that make daily lives a little bit easier, in every aspect, are being produced on an industrial scale at thousands of tons per year. However, several scientists, researchers, politics, and ordinary citizens have stated their concern regarding the life cycle, collateral effects, and final disposal of these cutting-edge materials. This review summarizes, describes, and discusses all manuscripts published in the Journal Citation Reports during the last 10 years, which studied the toxicity or the effects of nanomaterials on human and environmental health. It was observed that 23.62% of the manuscripts analyzed found no ecological or human risks; 54.39% showed that several nanomaterials have toxicological effects on the ecosystems, human, or environmental health. In comparison, only 21.97% stated the nanomaterials had a beneficial impact on those. Although only 54.39% of the manuscripts reported unfavorable effects of nanomaterials on ecosystems, human, or environmental health, it is relevant because the potential damage is invaluable. Therefore, it is imperative to make toxicological studies of nanomaterials with holistic focus under strictly controlled real conditions before their commercialization, to deliver to the market only innocuous and environmentally friendly products.
