Abstract
As the demand for NPs based goods has increased, near environmental concentrations of metal and oxide nanoparticles have risen. This poses a serious problem for sustainable agriculture. There has been evidence that metal NPs and metal oxide NPs have adversely affected growth, yields and quality of important agricultural crops. Numerousstudies have shown that NPs have negative effects at biochemical, physiological, and molecular levels. Under low NPs toxicity, antioxidant enzyme activities in crops increased while the activities decreased at higher NPs toxicity. NPs altered mineral nutrition, photosynthesis, and caused oxidative stress as well as genotoxicity. The exposure of crop plants to NPs caused the concentration of NPs in different plant parts, including fruits and grains, which could be passed on to humans through the food chain. Therefore, the vast majority of NPs have both positive and negative effects on crops at the physiological, morphological, biochemical, and molecular levels. Plants react differently to NPs depending on various factors such as the species, stages of growth, conditions, and method of exposure, in addition to the dose and duration. Nanotechnology in various industries may cause a huge environment dispersion of nanoparticles. Concerns about nanoparticles interaction with flora and fauna is raised due to a growing load of it in the environment. Findings suggest oxidative burst as a general mechanism through which the toxic effects of nanoparticle are spread in plants. This review article also recommends future research directions.
