“…Despite a high dispersion of reported data, a significant trend of difference among AOPs' efficiency, as measured by EEO, could be observed. Regarding economic considerations alone, referred to EEO values, radiolysis appears to be the most suitable technique [41]. Considering traditional AOPs, EEO values for UV/H 2 O 2 are much lower than those for UV and photocatalysis; at the same time, UV techniques have generally higher energy consumption, and are less efficient in elimination of degradation by-products.…”

“…Comparison of EEO values for imidacloprid degradation using TiO 2 photocatalysis (TiO 2 1 g/L), radiolysis and UV/VUV photolysis showed high values for UV (EEO = 60), lower for both UV/VUV (combination of UV at 254 nm and VUV at 185 nm) and TiO 2 /UV (15) and extremely low for radiolysis (0.25) [41]. Considering the fact that EB requires only direct energy consumption (no "stored energy" components) and its technology has intrinsic high conversion efficiency (input electric to output radiation energy), EB could be considered one of the most efficient AOPs currently available, with energy demand smaller by approximately two order of magnitude as those of other methods.…”

The presence of ‘emerging contaminants’, i.e., chemicals yet without a regulatory status and poorly understood impact on human health and environment, in wastewater and aquatic environments is widely reported. No established technology, to date, can simultaneously and completely remove all these contaminants, even though some Advanced Oxidation Processes (AOPs,) have demonstrated capacity for some degradation of these compounds. High-energy, radiolytic processing of water matrices using various sources: electron beam (EB), ɣ-rays or non-thermal plasma (NTP) have shown excellent results in many applications, although these remain at the moment isolated examples and scarcely known. High-energy irradiation constitutes an additive-free process that uses short-lived, highly reactive radicals (both oxidating and reducing) generated by water radiolysis, which can instantaneously decompose organic pollutants. Several studies have demonstrated its effectiveness, as a stand-alone process or combined with others, in the rapid decomposition (up to complete mineralization) of organic compounds in pure and complex solutions, and in the removal or inactivation of microorganisms and parasites, without production of leftover residual compounds in solution. High-energy oxidation processes (a.k.a. Advanced Oxidation & Reduction Processes—AORPs) could have a primary role in future strategies addressing emerging contaminants.

“…Imidacloprid (IDP), a typical neonicotinoid, is commonly used to control agricultural pests such as whiteflies, lepidoptera, and beetles and is one of the most used insecticides worldwide [ 170 , 171 ]. However, when a large quantity of IDT is absorbed by both vertebrates and invertebrates in the environment, the IDP residues cause a significant health risk to humans [ 172 ].…”

In recent times, food safety has become a topic of debate as the foodborne diseases triggered by chemical and biological contaminants affect human health and the food industry’s profits. Though conventional analytical instrumentation-based food sensors are available, the consumers did not appreciate them because of the drawbacks of complexity, greater number of analysis steps, expensive enzymes, and lack of portability. Hence, designing easy-to-use tests for the rapid analysis of food contaminants has become essential in the food industry. Under this context, electrochemical biosensors have received attention among researchers as they bear the advantages of operational simplicity, portability, stability, easy miniaturization, and low cost. Two-dimensional (2D) nanomaterials have a larger surface area to volume compared to other dimensional nanomaterials. Hence, researchers nowadays are inclined to develop 2D nanomaterials-based electrochemical biosensors to significantly improve the sensor’s sensitivity, selectivity, and reproducibility while measuring the food toxicants. In the present review, we compile the contribution of 2D nanomaterials in electrochemical biosensors to test the food toxicants and discuss the future directions in the field. Further, we describe the types of food toxicity, methodologies quantifying food analytes, how the electrochemical food sensor works, and the general biomedical properties of 2D nanomaterials.

“…Human health is significantly influenced by the presence of pesticides in drinking water, and some of these pesticides are known to be carcinogens. They not only influence the people involved in agriculture but also are carried to long distances because of their longer half-lives and entering the water bodies in the end [6, 7, 8, 9, 10]. This scenario is worsened in countries like Iran due to limited water resources and existing resources being polluted by the reckless and unnecessary use of the agrochemicals [11].…”

This work has attempted to investigate the potential of ZnO/CoFe2O4 magnetic nanocomposite to mineralize imidacloprid completely to have sustainable pollutant free and safe water supply. The co-precipitation method was performed to prepare the composites; was performed to characterize composites, scanning electron microscope (SEM), transmission electron microscopy (TEM), energy dispersive x-ray crystallography (EDX), x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and vibrating sample magnetometer (VSM). It was attempted to explore and enhance parameters influencing the process and the percentage of imidacloprid degradation, including photocatalyst amount, pesticide concentration, pH, radiation time, and temperature. UV-Vis spectrophotometer was used for the degradation percent of organochlorine pesticides. Parameters affecting the process, including photocatalyst amount, pesticide concentration, pH, radiation time, and temperature effect on the percentage of imidacloprid degradation were Investigated and optimized. 0.05 g of photocatalyst, with a concentration of 5 ppm for 45 min under light exposure was obtained at pH 10 at room temperature.
