“…Efforts have been made to characterize catalysts for their pore size, density, and porosity in order to achieve better catalytic efficiency of heterogeneous Fenton-like reactions. A number of catalysts have been applied to carry out heterogeneous Fenton reactions (Costa et al 2008;Diao et al 2017Diao et al , 2018García-Rodríguez et al 2017;Mirzaei et al 2017;Morales-Pérez et al 2016a;Nidheesh et al 2017;Oturan et al 2018;Ouiriemmi et al 2017;Pi et al 2018).…”

Nowadays, the water ecosystem is being polluted due to the rapid industrialization and massive use of antibiotics, fertilizers, cosmetics, paints, and other chemicals. Chemical oxidation is one of the most applied processes to degrade contaminants in water. However, chemicals are often unable to completely mineralize the pollutants. Enhanced pollutant degradation can be achieved by Fenton reaction and related processes. As a consequence, Fenton reactions have received great attention in the treatment of domestic and industrial wastewater effluents. Currently, homogeneous and heterogeneous Fenton processes are being investigated intensively and optimized for applications, either alone or in a combination of other processes. This review presents fundamental chemistry involved in various kinds of homogeneous Fenton reactions, which include classical Fenton, electro-Fenton, photo-Fenton, electro-Fenton, sono-electro-Fenton, and solar photoelectron-Fenton. In the homogeneous Fenton reaction process, the molar ratio of iron(II) and hydrogen peroxide, and the pH usually determine the effectiveness of removing target pollutants and subsequently their mineralization, monitored by a decrease in levels of total organic carbon or chemical oxygen demand. We present catalysts used in heterogeneous Fenton or Fenton-like reactions, such as H 2 O 2-Fe 3+ (solid)/nano-zero-valent iron/immobilized iron and electro-Fenton-pyrite. Surface properties of heterogeneous catalysts generally control the efficiency to degrade pollutants. Examples of Fenton reactions are demonstrated to degrade and mineralize a wide range of water pollutants in real industrial wastewaters, such as dyes and phenols. Removal of various antibiotics by homogeneous and heterogeneous Fenton reactions is exemplified.

“…Atrazine in environments can be dissipated by the following methods: oxidative degradation by zero-valent metals ( Diao et al, 2020 ), photolysis ( Souza et al, 2014 ), advanced oxidation processes ( Morales-Perez et al, 2016 ), or bioremediation. As an eco-friendly, efficient, and low-cost method, bioremediation has been proposed as the most promising method to remove atrazine from contaminated-sites.…”

Atrazine, a triazine herbicide, is widely used around the world. The residue of atrazine due to its application in the fore-rotating crop maize has caused phytotoxicity to the following crop sweet potato in China. Bioaugmentation of atrazine-contaminated soil with atrazine-degrading strains is considered as the most potential method to remove atrazine from soil. Nevertheless, the feasibility of bioaugmentation and its effect on soil microbiome still need investigation. In this study, Paenarthrobacter sp. AT-5, an atrazine-degrading strain, was inoculated into agricultural soils contaminated with atrazine to investigate the bioaugmentation process and the reassembly of the soil microbiome. It was found that 95.9% of 5 mg kg−1 atrazine was removed from the soils when inoculated with strain AT-5 with 7 days, and the phytotoxicity of sweet potato caused by atrazine was significantly alleviated. qRT-PCR analysis revealed that the inoculated strain AT-5 survived well in the soils and maintained a relatively high abundance. The inoculation of strain AT-5 significantly affected the community structure of the soil microbiome, and the abundances of bacteria associated with atrazine degradation were improved.

“…ATZ also induces oxidative stress by the formation of reactive oxygen species resulting in the reduced semen quality, sperm dysfunction and infertility of amphibians, rats and pigs (Kumar V., 2013); (Huang H., 2009); (Glaesner N., 2014). Atrazine is known to cause hepatic damage, as the liver is the primary organ for atrazine metabolism in mammals (Vonberg D., 2014); (Morales-Pérez A.A., 2016). Atrazine is also responsible for cardiotoxicity in mice by disruption of ionic balance (Mahler B.J., 2017) (Victor-Costa A.B., 2010.…”

The aim of this study was to examine the cytotoxicity of the herbicide atrazine on the reproductive system. 48 male and 48 female albino rats were treated with atrazine daily for two different durations (15 and 30 days).Reproductive system toxicity was monitored by quantitative analysis of the serum Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Prolactin (PRL), Estrogen (E2), Progesterone (Prog) and Testosterone (Testo). On the other hand, the reproductive organs were collected for histopathology study. The study showed a significant elevation of estrogen, progesterone hormones with a significant decrease in testosterone hormone in male groups while in female groups there was a significant decrease in estrogen, progesterone & hormones with a significant increase in testosterone hormone. But there was no effect on PRL and LH hormones in both male and female groups toxified by ATZ, in comparison to the control groups. In addition to that, the Light microscopic examination of the seminiferous tubule cells (st) showed vacuolations within seminiferous tubules (V), degeneration of spermatozoa formation and hemorrhage (hg) in the interstitial tissue. These effects were increased by increasing the dose or the time of exposure. By using ascorbic acid in the treatment of those effects, we find a significant improvement and detoxification of the atrazine effects on both hormonal tests and histological sections. From our study results, we concluded that there is a potential contribution of herbicide mixtures in the etiology of somebody's diseases, while ascorbic acid has beneficial effects as it tends to dampen atrazine toxicity, in albino rats.
