“…Several other studies have indicated that AgNPs of different sizes in variable concentrations can lead to morphological changes in plants, in addition, it can also influence the reduction in root/shoot and overall biomass (Hawthorne et al 2012, Yin et al 2012, Mirzajani et al 2013, Pokhrel and Dubey 2013, Qian et al 2013, Zuverza-Mena et al 2016, Tripathi et al 2017, Vinković et al 2017. Different studies have shown that the plants exposed to AgNPs produce a higher amount of reactive oxygen species (ROS) and antioxidant molecules (Dimkpa et al 2013, Jiang et al 2014, Belava et al 2017, Tripathi et al 2017. Few studies have shown a significant decline in photosynthetic pigment contents as a response to AgNPs exposure (Qian et al 2013, Tripathi et al 2017.…”

Silver nanoparticles (AgNPs) are used in several industries and their continuous release into environment can damage the ecosystem. Our study observed the impact of two concentrations of AgNPs (1 and 5 mM) on wheat seedlings. In this study, the treatment of AgNPs was found to have a significant impact on growth parameters, such as root and shoot length of wheat seedlings, in addition to that biochemical parameters, such as activity of catalase, glutathione, flavonoid, and chlorophyll concentrations, were also affected. AgNPs apparently suppressed the photosynthetic activity of the seedlings, with a clear destruction of photosystems at 5 mM concentration. The result also indicated an improper regulation of PSI electron transport, resulting in a damage to chloroplast structure, including photosystem itself. Our study presents a mechanism of the AgNPs action of on photosynthetic processes in plants.

“…The migrations and behaviour of these pollutants can pose environmental and human risks [10], [13][14][15] This has provoked discussions about the safety of, and potential risks associated with, nanotechnology. A strong emphasis has been placed on determining the toxicity of nanostructures to various groups of organisms, including perennials, wheat, bacteria, protozoa, macrophytes, earthworms, fish, mice and rats [16][17][18][19][20][21][22][23][24][25]. It also appears extremely important to determine the characteristics and stability of nanoparticles in order to understand how they function in aqueous solutions and interact with standard substances in the environment [1], [9][10][11][12].…”

“…Dlatego też nanotechnologia jest przedmiotem dyskusji w kontekście bezpieczeństwa i ryzyka. Duży nacisk położony jest na określenie toksyczności nanostruktur w odniesieniu do różnych grup organizmów, w tym bylin, pszenicy, bakterii, pierwotniaków, makrofitów, dżdżownic, ryb, myszy, szczurów [16][17][18][19][20][21][22][23][24][25]. Określenie cech i stabilności nanocząstek jest bardzo istotne, gdyż pozwala także zrozumieć ich funkcjonowanie w roztworach wodnych oraz w interakcji z podstawowymi substancjami obecnymi w środowisku [1], [9][10][11][12].…”

Nanocząstki metali w wodach powierzchniowych -zagrożenie dla organizmów wodnychABSTRACT Purpose: The aim of this paper is to provide information on the risks posed by metal nanoparticles released into surface waters. Introduction: Currently, the use of nanoparticles of metal and metal oxides (NPMOs) is extremely popular in various industries, and in medicine and households. Nanoparticles and nanocompounds have become significant contributors to technological progress due to their physicochemical properties such as the melting point, electrical and thermal conductivity, catalytic activity, light absorption and scattering, as well as biocompatible and bactericidal properties. These functions cause their increased performance compared to their macro counterparts. However, it should be noted that the properties of nanocomponents can create new risks to the environment and consumers. Based on existing literature, a conclusion can be drawn that metal nanoparticles are a potential threat to plant and animal organisms, and humans. It is, therefore, necessary to intensify efforts to understand the mobility, reactivity and durability of nanocomponents in various environmental components, especially in the aquatic environment, and their toxicity to organisms. Methodology: This paper is a literature review. Conclusions:The increasing use of nanosubstances, in both commercial and industrial products, has caused an increasing concentration and diversity of these substances in aquatic ecosystems. Based on the analysis of literature reports, it can be concluded that the size of nanoparticles, their structure and arrangement, as well as surface properties, are subject to constant changes in the environment as a result of their interactions with other components, and of the balances shaped by a variety of geochemical and biological factors. Numerous studies conducted in recent years in the field of nanoecotoxicology have demonstrated the existence of a risk to aquatic organisms, which could lead to their impaired development and even death. Unfortunately, the lack of a standard technique for assessing the toxicity of nanoparticles in various biological systems, such as the reproductive, respiratory, nervous and gastrointestinal systems, and the developmental stages of aquatic organisms, makes it impossible to conduct such studies in a standardised fashion. Reports of the toxicity of metal and metal oxide nanoparticles in relation to various forms of living organisms warrant in-depth investigations into how these particles function in aqueous solutions and interact with standard substances.

The increasing global population has forced the agricultural area to enhance the yield of crop, thereby fulfilling the requirements of people. The advancement has led to synthesis of nanomaterials with different size, shapes, and biocompatibility aspects towards specific applications like agriculture. Several nanomaterials such as metal, metal oxide, carbon nanotubes (CNTs), carbon nanofibers (CNFs), graphene, and its derivatives have shown potential ability for augmenting the yield of crops and protect crops against pathogens. However, these nanomaterials required smart delivery system that might easily deliver the nanofertilizers in a controlled manner. In this context, the incorporation of nanotechnology and polymer science might be developing newer technology with minimal usage and maximum effectiveness for improvement of crops. The incorporation of nanomaterials in polymeric composites offers newer approaches for agricultural delivery system that might provide various advantages such as higher stability, solubility, uniform distribution, and controlled release. Moreover, nanomaterials have potential ability for advancement in the genetic engineering. Herein, we discuss the role of nanomaterials in the growth of the plant, polymeric nanocomposite materials for agriculture delivery system with the advancement in the genetic engineering, and future prospects of these polymeric-nanocomposite materials in agriculture.
