“…The stability of nanoparticles/nanofertilizers is mainly controlled by the environmental conditions, which include rhizosphere and exudates of roots, soil pH, salinity, soil CEC, soil mater content, and soil pollution [ 81 ]. After synthetic NPs are formed, they tend to evolve toward a more stable thermodynamic state, through interacting with surrounding molecules or undergoing physicochemical transformations such as corrosion, aggregation, and dissolution [ 20 ].…”

Strawberry production presents special challenges due the plants’ shallow roots. The rooting stage of strawberry is a crucial period in the production of this important crop. Several amendments have been applied to support the growth and production of strawberry, particularly fertilizers, to overcome rooting problems. Therefore, the current investigation was carried out to evaluate the application of biological nanofertilizers in promoting strawberry rooting. The treatments included applying two different nanofertilizers produced biologically, nano-selenium (i.e., 25, 50, 75, and 100 mg L−1) and nano-copper (i.e., 50 and 100 mg L−1), plus a control (untreated seedlings). The rooting of strawberry seedlings was investigated by measuring the vegetative growth parameters (root weight, seedling weight, seedling length, and number of leaves), plant enzymatic antioxidants (catalase, peroxidase, and polyphenol oxidase activity), and chlorophyll content and its fluorescence and by evaluating the nutritional status (content of nutrients in the fruit and their uptake). The results showed that the applied nanofertilizers improved the growth, photosynthetic pigments, antioxidant content, and nutritional status of the seedlings compared to the control. A high significant increase in nutrient contents reached to more than 14-fold, 6-fold, 5-folf, and 4-fold for Cu, Mn, N, and Se contents, respectively, due to the applied nanofertilizers compared with the control. The result was related to the biological roles of both Se and CuO in activating the many plant enzymes. Comparing the Se with the CuO nanofertilizer, Cu had the strongest effect, which was shown in the higher values in all studied properties. This study showed that nanofertilizers are useful to stimulate strawberry seedling growth and most likely would also be beneficial for other horticultural crops. In general, the applied 100 ppm of biological nano-Se or nano-CuO might achieve the best growth of strawberry seedlings under growth conditions in greenhouses compared to the control. Along with the economic dimension, the ecological dimension of biological nanofertilizers still needs more investigation.

“…This implies that particle aggregation can decrease the number of plastic particles to which organisms are effectively exposed. Aggregation is influenced by the composition of the exposure medium (e.g., the size of the natural colloids and soil particles 34 ) or by the salinity and presence of natural organic matter 17 . To perform a valuable toxicity test, it is necessary to monitor the aggregation behavior of the particles in the respective exposure medium.…”

Despite the increasing concern about the harmful effects of micro-and nanoplastics (MNPs), there are no harmonized guidelines or protocols yet available for MNP ecotoxicity testing. Current ecotoxicity studies often use commercial spherical particles as models for MNPs, but in nature, MNPs occur in variable shapes, sizes and chemical compositions. Moreover, protocols developed for chemicals that dissolve or form stable dispersions are currently used for assessing the ecotoxicity of MNPs. Plastic particles, however, do not dissolve and also show dynamic behavior in the exposure medium, depending on, for example, MNP physicochemical properties and the medium's conditions such as pH and ionic strength. Here we describe an exposure protocol that considers the particle-specific properties of MNPs and their dynamic behavior in exposure systems. Procedure 1 describes the top-down production of more realistic MNPs as representative of MNPs in nature and particle characterization (e.g., using thermal extraction desorption-gas chromatography/mass spectrometry). Then, we describe exposure system development for short-and long-term toxicity tests for soil (Procedure 2) and aquatic (Procedure 3) organisms. Procedures 2 and 3 explain how to modify existing ecotoxicity guidelines for chemicals to target testing MNPs in selected exposure systems. We show some examples that were used to develop the protocol to test, for example, MNP toxicity in marine rotifers, freshwater mussels, daphnids and earthworms. The present protocol takes between 24 h and 2 months, depending on the test of interest and can be applied by students, academics, environmental risk assessors and industries. Key points• In nature, micro-and nanoplastics (MNPs) occur in various shapes, sizes and chemical compositions. Each of these properties can affect both their dynamic behavior and their toxicology and should be considered when performing ecotoxicology experiments to assess their risk.• Here, MNPs are generated from plastic waste by using either a ball or centrifugal mill. Their physicochemical properties are measured. Ecotoxicology experiments in soil and aquatic systems are described.

In recent years, the constant challenge of finding cost-effective and sustainable alternatives has become a difficult task for all researchers worldwide. While it is true, scientific advances have been rich within this branch of green chemistry; However, there are still methodologies to be improved. This systematic review was elaborated in relation to nanotechnology and its application in agricultural field as nanofertilizers; with the aim of contributing to the community, in terms of state of the art, with the latest scientific advances in the application of nanoparticles (NPs) as new emerging technologies, in favor of the phenological development of plants and/or crops. This research could be developed from the analysis of research articles, using the PRISMA methodology, with which it was possible to collect around 200 articles; of which, considering various inclusion and exclusion criteria, among the main ones, those articles published between 2019 and 2022, 50 indexed and Q1 articles were selected. Each of these were compiled into registration matrices, characteristics and categories; Thanks to this, it was determined that 48%were published in 2022; followed by 32% found in 2021, signaling that nanotechnology will continue to advance over the years.Similarly, various methods for improving agriculture were considered in the category matrix. Finally, it was determined that, although nanofertilizers as emerging technologies contribute a large percentage in the structural development of the phenological characteristics of the plant, there are side effects; So it is important to take into account background, in order to achieve the incorporation of this new green technology in agro-industrial development.
