Afficher plus [+] Moins [-]Metal-based nanoparticles (NPs) are one of the most manufactured nanomaterials and deserve singular attention given their continuous input to the environment, lack of degradation, and accumulation risk. In agricultural soils, the use of organic amendments and wastewater and the application of nanotechnology are important NP inputs. Metal-based NPs have beneficial applications as fertilizers and increase plant resistance to pathogens and environmental abiotic stressors. Ag-, Zn-, Cu-, Ti-, and Ce-based NPs are the most widely used to improve crop production. NPs can also have negative impacts, including phytotoxicity, lower nutrient content in plants, and soil microorganism toxicity. The potential NP interaction with other soil contaminants, including metals and organic compounds, is a major concern because it can modify the bioconcentration or affect the intrinsic toxicity of both substances with the consequent biological impact on plants. Exposure to NP-contaminant mixtures may induce unexpected toxic effects via several different mechanisms that affect the availability, uptake, and metabolic processes involved in the detoxification and degradation of compounds. However, the mechanisms underlying the effects of the NP-contaminant interaction on joint toxicity are poorly understood. This chapter covers some of the most relevant issues concerning the effects of metal-based NPs on plants.
