“…For instance, in Swedish rivers and streams, concentrations of diflufenican can range between 10 to 100 ng/L (Boye et al, 2019), and up to 503 ng/L in Spanish rivers (Herrero-Hernández et al, 2020), being in many cases above the predicted non-effect concentrations (PNEC) for the environment (4.5 ng/L; Boström et al, 2017). The derived ecological risk of diflufenican in water bodies is mainly due to its high toxicity to algae, with an EC 50 value (72 h) ranging from 270 to 510 ng/L (Book et al, 2022;Weyman et al, 2012). Diflufenican is currently included in the watch list of substances for the European Union-wide monitoring in the field of water quality (EU Directive 2008/105/EC).…”

“…However, not much toxicity was observed for Ag NM. The aquatic ecotoxicity of manufactured silica NMs and their interactions with organic pollutants has been also studied in different studies [ 116 – 118 ]. In their studies, they investigated the ecotoxicity of nine silica NMs with different size, charge, surface modification, and shape in experiments with bacteria ( Pseudomonas putida ), algae ( Raphidocelis subcapitata ), crustacean ( Daphnia magna ), and fish gill cells ( Oncorhynchus mykiss ).…”

Nanomaterials: a review of emerging contaminants with potential health or environmental impact

Nanotechnologies have been advantageous in many sectors and gaining much concern due to the unique physical, chemical and biological properties of nanomaterials (NMs). We have surveyed peer-reviewed publications related to “nanotechnology”, “NMs”, “NMs water treatment”, “NMs air treatment”, and “NMs environmental risk” in the last 23 years. We found that most of the research work is focused on developing novel applications for NMs and new products with peculiar features. In contrast, there are relatively few of publications concerning NMs as environmental contaminants relative to that for NMs applications. Thus, we devoted this review for NMs as emerging environmental contaminants. The definition and classification of NMs will be presented first to demonstrate the importance of unifying the NMs definition. The information provided here should facilitate the detection, control, and regulation of NMs contaminants in the environment. The high surface-area-to-volume ratio and the reactivity of NMs contaminants cause the prediction of the chemical properties and potential toxicities of NPs to be extremely difficult; therefore, we found that there are marked knowledge gaps in the fate, impact, toxicity, and risk of NMs. Consequently, developing and modifying extraction methods, detection tools, and characterization technologies are essential for complete risk assessment of NMs contaminants in the environment. This will help also in setting regulations and standards for releasing and handling NMs as there are no specific regulations. Finally, the integrated treatment technologies are necessary for the removal of NMs contaminants in water. Also, membrane technology is recommended for NMs remediation in air.

This review delves into the mesmerizing technology of nano-agrochemicals, specifically pesticides and herbicides, and their potential to aid in the achievement of UN SDG 17, which aims to reduce hunger and poverty globally. The global market for conventional pesticides and herbicides is expected to reach USD 82.9 billion by 2027, growing 2.7% annually, with North America, Europe, and the Asia–Pacific region being the biggest markets. However, the extensive use of chemical pesticides has proven adverse effects on human health as well as the ecosystem. Therefore, the efficacy, mechanisms, and environmental impacts of conventional pesticides require sustainable alternatives for effective pest management. Undoubtedly, nano-agrochemicals have the potential to completely transform agriculture by increasing crop yields with reduced environmental contamination. The present review discusses the effectiveness and environmental impact of nanopesticides as promising strategies for sustainable agriculture. It provides a concise overview of green nano-agrochemical synthesis and agricultural applications, and the efficacy of nano-agrochemicals against pests including insects and weeds. Nano-agrochemical pesticides are investigated due to their unique size and exceptional performance advantages over conventional ones. Here, we have focused on the environmental risks and current state of nano-agrochemicals, emphasizing the need for further investigations. The review also draws the attention of agriculturists and stakeholders to the current trends of nanomaterial use in agriculture especially for reducing plant diseases and pests. A discussion of the pros and cons of nano-agrochemicals is paramount for their application in sustainable agriculture.

Colloidal silica nanomaterials reduce the toxicity of pesticides to algae, depending on charge and surface area

Abstract: Colloidal silica nanomaterials are promising adsorbents for aquatic pollutants. The present study quantifies the toxicity reduction of differently charged pesticides (paraquat (cationic), pentachlorophenol (anionic) and diflufenican (uncharged)) by co-exposure to...
