“…In the case of Chl-b, MWCNTs slightly reduced the decreasing effect of ZnO NPs ( Fig 2C ). Previously, a similar reduction in total chlorophyll content was reported in green leaves of Pisum sativum , Salvinia natans , and Arabidopsis thaliana treated with ZnO NPs [ 43 – 45 ], which was probably due to impaired photosynthesis and reduced biomass accumulation [ 46 ].…”

Phytotoxicity of zinc oxide nanoparticles and multi-walled carbon nanotubes, alone or in combination, on Arabidopsis thaliana and their mutual effects on oxidative homeostasis

The extensive use of engineered nanoparticles (ENPs) has raised concerns about their potentially harmful effects on the ecosystem. Despite previous reports of a variety of individual ENPs, the mutual effects of ENPs when used in combination were not well understood. In this study, we first investigated the effects of different sizes and concentrations of ZnO nanoparticles (ZnO NPs) or multi-walled carbon nanotubes (MWCNTs) on the growth performance of Arabidopsis thaliana seedlings. Then, two concentrations of ZnO NP (40 and 50 mg/L) with a diameter of 90 nm and MWCNTs (100 and 500 mg/L) with an outer diameter of 40–60 nm were used to evaluate their respective or simultaneous phytotoxicity to Arabidopsis. The results showed that seedlings exposed to either ZnO NPs or MWCNTs exhibited significant phytotoxic symptoms. ZnO NPs caused stronger inhibitory effects than MWCNTs on several plant growth indices, including reduced root length, chlorophyll content, and increased ROS concentration. When applied together, the concurrent effects of ZnO NPs and MWCNTs on Arabidopsis seedlings appeared to be more negative, as evidenced not only by the further deterioration of several growth indices but also by their synergistic or additive regulation of the activities of several antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT) and glutathione reductase (GR). Moreover, qRT-PCR analysis revealed that in the presence of ZnO NPs and MWCNTs, the expression of genes important for maintaining cellular ROS homeostasis was differentially regulated in shoots and roots of Arabidopsis seedlings. Overall, our data may provide new insights into how plants respond to more than one type of nanomaterial and help us better understand the associated environmental risks.

“…The effects on T. pseudonana and C. gracilis showed growth inhibition, while P. tricornutum showed that its growth got reduced proportionally depending on the concentration increase. Wang et al [ 94 ] performed an evaluation where seeded Arabidopsis thaliana species in soil were irrigated with ZnO NPs at different concentrations (0–300 mg/L) for 6 weeks. Results indicated that notorious oxidative stress was generated by Zn 2+ ions in the plant cells, resulting in cellular toxicity.…”

Environmental Impact of Nanoparticles’ Application as an Emerging Technology: A Review

The unique properties that nanoparticles exhibit, due to their small size, are the principal reason for their numerous applications, but at the same time, this might be a massive menace to the environment. The number of studies that assess the possible ecotoxicity of nanomaterials has been increasing over the last decade to determine if, despite the positive aspects, they should be considered a potential health risk. To evaluate their potential toxicity, models are used in all types of organisms, from unicellular bacteria to complex animal species. In order to better understand the environmental consequences of nanotechnology, this literature review aims to describe and classify nanoparticles, evaluating their life cycle, their environmental releasing capacity and the type of impact, particularly on living beings, highlighting the need to develop more severe and detailed legislation. Due to their diversity, nanoparticles will be discussed in generic terms focusing on the impact of a great variety of them, highlighting the most interesting ones for the industry.

“…Increasing the silver nanoparticle concentration over the range of 0.1 to 1000mgL -1 and increasing the size of the silver nanoparticles over the 20-150nm diameter range increased the inhibition effect upon seed germination and seedling growth [8]. The size and dose of nanoparticles play an important role in their behavior, reactivity and toxicity [83].…”

Nanoparticles are becoming popular from their use in medicine for therapy, diagnostics and imaging, in pharmacy for drug delivery, to its use in electronics, engineering and manufacturing industries. This wide application has increased their presence in the environment especially in wastewater from municipal and industrial sources. They end up in the fi nal product; biosolids which are treated sewage sludge from wastewater treatment plants. Due to limited space in landfi lls and cost effectiveness, biosolids are predominantly disposed in land applications as organic fertilizer for crop production or land reclamation. Nanoparticles have been detected in wastewater and biosolids raising concerns about their effect on soil health and crop growth. While a large number of studies have been conducted on effect of nanoparticles on seed germination and plant growth, few studies have been carried out using biosolids. The sole effect of nanoparticles may be different from when it's present in biosolids due to reaction with some components in biosolids. Hence more work is needed in this area to provide direction for regulation of biosolids. Studies have reported both positive and negative effects of nanoparticles on plant growth showing that it depends on plant species, type of nanoparticle, and dose of nanoparticle and method of application. There is also very little work on effect of nanoparticles on soil health. Most of the work done has shown the antimicrobial effect of some nanoparticles which could affect nutrient release from the organic matter fraction in the soil and disrupt some plant-microbe relationships that promote soil fertility. Although nanoparticles have proved benefi cial in many aspects of life, they need to be monitored due to their increasing use in the environment.
