Atrazine, an herbicide used to control grassy and broadleaf weed, has become an essential part of agricultural crop protection tools. It is widely sprayed on corn, sorghum and sugar cane, with the attendant problems of its residues in agri-food and washing water. If ingested into humans, this residual atrazine can cause reproductive harm, developmental toxicity and carcinogenicity. It is therefore important to find clean and economical degradation processes for atrazine. In recent years, many physical, chemical and biological methods have been proposed to remove atrazine from the aquatic environment. This review introduces the research works of atrazine degradation in aqueous solutions by method classification. These methods are then compared by their advantages, disadvantages, and different degradation pathways of atrazine. Moreover, the existing toxicological experimental data for atrazine and its metabolites are summarized. Finally, the review concludes with directions for future research and major challenges to be addressed.

“…This fact, along with the evidence that disinfection using Ru was much less affected than BDD when O 3 was not applied, suggests that EO with Ru as anode is based mainly on the direct effect of the electrical pulse while using BDD involves •OH production as major disinfection mechanism. Therefore, for disinfection purposes, the use of Ru instead of BDD can be recommendable, although for other purposes (focused on removal of organic matter and/or pollutants such as pesticides, that may be present in the fresh-cut washing water), BDD is foreseen to provide better results than Ru (Contreras et al 2020).…”

Alternative sanitizing agents are required in fruit and vegetable processing industry, capable of effectively disinfecting both the product and the washing water to increase its reuse, while not producing harmful by-products like chlorine-based agents. In the present work, electro-oxidation (EO) and ozone are proposed for vegetable process water reuse, being optimised for their individual and combined application. The application of hybrid electro-oxidation and ozone achieved 7 log reduction after 15 min of treatment in batch using BDD as anode material, showing important synergistic effects when compared with the individual treatments. When the process was applied in continuous mode, up to 6 log reduction of total bacteria was achieved using EO alone with Ru as anode and stainless steel as cathode, under 11 mA/cm2 of current density, a cell retention time of 12 s and no addition of chemical reagents (electrolyte). Under these conditions, the absence of microorganisms in water was maintained for more than 24 h, no harmful by-products (chlorate, bromate) were detected and no damages to lettuce seeds were observed when evaluating water reuse potential.

“…Also, a new and interesting concept called 'technology readiness level' (TRL) firstly applied by NASA in 1974 has appeared to evaluate the level of maturity that a technology has reached. Thus, during the last quarter of the last century, the TRL applied to soil washing technology for the remediation of soils polluted with hazardous organic compounds increased from very low values (3)(4) to almost level 7-9, with all elements of the required value chain in full operation for the simpler technologies and, even, companies that are selling key-on-hand solutions to real problems. However, there is still a lot of work to be done regarding the optimization in the combination of processes and the effect of the formulation of the washing fluids, with many studies whose TRL should still need to be largely improved [47] to reduce the big gap in their development and scaleup which it has to be considered in future research.…”

“…Recently, the development of treatment technologies related to the remediation of soils has gained lots of attention, because Society has started to be conscious of the importance of solving the problem of pollution into soils as soon as it is generated, preventing the spreading of the pollutants to avoid low efficient remediations [2,3]. The success of technologies developed in the last century does not only depend on the technology itself, but also on the origin and physical properties of the pollutants (such as water solubility and sorption characteristics) and the structure and soil composition.…”

Purpose of ReviewThis review is focused on the removal of chlorinated hydrocarbons (as representative of persistent pollutants) from soil by soil-washing techniques, paying special attention to the application of electrochemically assisted technologies for the treatment of the liquids and gases produced during this treatment. It considers the degree of maturity of the technologies and suggests challenges for future research. Recent FindingsElectrochemical technologies can help to improve the overall efficiency of soil washing processes in the removal of chlorinated hydrocarbons, contributing to the depletion of these hazardous species from the soil washing liquid and gaseous effluents generated during the treatment of the soil.
