“…The results indicated that the combined technology significantly enhanced the accumulation of atrazine in plant tissues when comparing with the phytoremediation process alone, and the total accumulation increased by 20-30% [99]. At the same time, they carried out an electrokinetic-assisted ryegrass (Lolium perenne L.) phytoremediation test; it showed that the total removal of atrazine by ryegrass increased by 7%, with the help of low voltage gradients [100].…”

Atrazine is a kind of triazine herbicide that is widely used for weed control due to its good weeding effect and low price. The study of atrazine removal from the environment is of great significance due to the stable structure, difficult degradation, long residence time in environment, and toxicity on the organism and human beings. Therefore, a number of processing technologies are developed and widely employed for atrazine degradation, such as adsorption, photochemical catalysis, biodegradation, etc. In this article, with our previous research work, the progresses of researches about the treatment technology of atrazine are systematically reviewed, which includes the four main aspects of physicochemical, chemical, biological, and material-microbial-integrated aspects. The advantages and disadvantages of various methods are summarized and the degradation mechanisms are also evaluated. Specially, recent advanced technologies, both plant-microbial remediation and the material-microbial-integrated method, have been highlighted on atrazine degradation. Among them, the plant-microbial remediation is based on the combined system of soil-plant-microbes, and the material-microbial-integrated method is based on the synergistic effect of materials and microorganisms. Additionally, future research needs to focus on the excellent removal effect and low environmental impact of functional materials, and the coordination processing of two or more technologies for atrazine removal is also highlighted.

“…Chirakkara et al [15] and Acosta-Santoyo et al [16] applied the combined EKPR technology to a mixed contaminated soil (by heavy metals and polycyclic aromatic hydrocarbons), although they did not find a significant improvement in the removal efficiency as compared to that of phytoremediation experiments. However, we have recently shown that a moderate electric field (1-2 V cm -1 ) can significantly improve the atrazine removal by maize and ryegrass [17][18][19]; Rocha et al [20] have reported an enhancement of removal efficiency and plant biomass by using EKPR with reversal polarity and maize for the treatment of a soil spiked with petroleum. The relevance of the abovementioned results highlights the need to continue studying the application of EKPR to organic pollutants.…”

“…With regard to electrokinetic remediation, our research group have reported several studies focused on the electrokinetic flushing of organic pesticides at large scales [25][26][27][28]. Based on the success of the application of EKPR to atrazine-spiked soils using ryegrass (Lolium perenne L.) [19], in this work we report the application of EKPR to a low permeability soil spiked with atrazine using a mesocosm that contained 0.386 m 3 of soil planted with ryegrass. This plant species was selected mainly due to its fine and profuse fasciculated root system which can maximize the surface area in contact with the soil; so, it results in an ideal vegetative cover for the in situ treatment of contaminated soils [29].…”

“…It has been reported that atrazine affects human immune, endocrine and reproductive systems, while in severe cases it may lead to malformations and induce mutations, which are potentially carcinogenic to humans [4][5][15][16]. Therefore, atrazine's environmental behavior, particularly its transportation and fate, has received extensive research interest [16][17][18].…”

Background: Environmental behavior of pesticide in soils is a key current research focus. Studying the adsorption characteristics of pesticides in soils as a parameter for evaluating the risk of groundwater pollution by pesticides, is commonly applied in agriculture. Results: In order to provide a theoretical basis for environment risk assessment and pollution remediation, the thermodynamics and kinetics of the equilibrium of atrazine adsorption in the Three Gorges Reservoir area were assessed and analyzed via batch experiments. Results showed that the sorption of atrazine was an exothermic and spontaneous process at temperatures of 298–318K. Atrazine was more easily adsorbed by soils at concentrations of 0–30 mg·L-1, with low temperature adsorption being more effective than high temperature adsorption. The adsorption of atrazine to the two assessed soils were well fitted by the Freundlich and Langmuir models. The adsorption kinetics of atrazine in soils were consistent with the quasi-second order kinetic model and intraparticle diffusion was found not to be the only control step. The monolayer adsorption occurred with non-uniform energy distribution on the soil surface, indicating that the adsorption of atrazine by the two kinds of soil was controlled by internal diffusion surface adsorption and liquid film diffusion, leading to the complexity of its adsorption kinetics. The values of standard free energy <0, indicated that the adsorption of atrazine in soils was spontaneous and dominated by physical adsorption. Changes in standard enthalpy ( ) indicated that the adsorption was exothermic. Conclusion: Atrazine exhibited a weak adsorption capacity in both soils, indicating it is highly mobile in the soil-water environment and can easily cause groundwater pollution. Therefore, much attention should be paid to the environmental behavior of pesticide soil moisture fluctuations, potentially leading to the broad transfer and spread of pollution.
