“…As one of the most commonly applied triazinic herbicides, atrazine (2-chloro-4ethylamino-6-isopropylamino-1,3,5-triazine) leads to global problem of soil and water pollution owing to its massive usage, high chemical stability, apparent mobility, and significant toxicity to humans and ecosystems (Douglass et al, 2017;Sánchez et al, 2017). Although atrazine has been banned for future use in the European Union, it is allowed in many other countries including the United States and China, with an increasing annual consumption at a rate about 20% (Yue et al, 2017). Due to the high persistence in the environment, atrazine natural attenuation in soils takes extremely long time, normally years or even decades to occur (Domínguez-Garay et al, 2016).…”

Vermicomposting is an effective and environmentally friendly approach for eliminating soil organic contamination. Atrazine is one of the most commonly applied triazinic herbicides and frequently detected in agricultural soils. This study investigated the roles and mechanisms of two earthworm species (epigeic Eisenia foetida and endogeic Amynthas robustus) in microbial degradation of atrazine. Both earthworms accelerated atrazine degradation performance from 39.0% in sterile soils to 94.9%-95.7%, via neutralizing soil pH, consuming soil humus, altering bacterial community structure, enriching indigenous atrazine degraders and excreting the intestinal atrazine-degrading bacteria. Rhodoplanes and Kaistobacter were identified as soil indigenous degraders for atrazine mineralization and stimulated by both earthworm species. A. robustus excreted the intestinal Cupriavidus and Pseudomonas, whereas Flavobacterium was released by E. foetida. This study provides a comprehensive understanding of the distinct effects of two earthworm species on soil microbial community and atrazine degradation, offering technical supports to apply vermicomposting in effective soil bioremediation.

“…Sorption negative sites on organic matter and clay particles increase with increasing pH, as well as dissolution of part of organic matter, resulting in the reduction atrazine adsorption (Tao;Tang, 2004). However, increasing pH also increases deprotonation of atrazine and decrease sorption by physical adsorption, which increases hydrophobic partitioning interaction among atrazine molecules and the soil (Yue et al, 2017). Table 4: Freundlich isotherms adjusted for atrazine sorption at different treatment conditions in two layers of a Typic Hapludult.…”

“…The molecule's behavior as a weak base makes sorption on soil particles a component of retention or transport in soils. According to Yue et al (2017), the atrazine sorption in their tested soils was dominated by physical sorption, at low equilibrium concentration, and by hydrophobic partitioning, as concentration equilibrium increases; they also found that desorption of atrazine is favored at lower solution pH. Therefore, changing the soil chemical characteristics by lime and phosphate, such as increasing pH, affecting organic compounds and increasing negative charge on particles, can potentially increase contamination of soil and water.…”

Lime and phosphate effects on atrazine sorption, leaching and runoff in soil

et al. 2020

Atrazine still is a widely used herbicide in tropical soils to control annual broad-leaved weeds and annual grasses mainly in maize and sorghum plantations. Sorption and desorption in such soils are important processes that affect transport, ending with soil and water contamination, not only in these soils, but in other soils around the world. Lime and phosphate are important amendments in tropical soils to mitigate low fertility. These treatments can affect interaction among soil particles and between soil and atrazine. The objectives here were to evaluate the effect of lime, phosphate, and lime + phosphate treatments on sorption and transport of atrazine in a Typic Hapludult, using soil-erosion-plots at field conditions in a 3%-slope landscape 20 m away from the floodplain. Water- and sediment-sampler devices were used to measure runoff during an entire rainy season. Soil, water and sediments were sampled and analyzed for atrazine. By increasing pH and changing soil organic matter interaction with mineral particles, lime and lime + phosphate decreased sorption in the upper 20-cm layer. This affected leaching and runoff of atrazine, showing that when lime and lime + phosphate were applied to soil, this herbicide had more potential to go deeper in the soil profile, towards the groundwater, or to runoff towards the lower part of the landscape. However, even with increasing leaching, the amount of rainfall, and water infiltration, were enough to dilute atrazine into levels below the maximum contaminant level (MCL) of atrazine in drinking water.

“…In United States, atrazine has been registered for more than 50 years and it is also the most widely used herbicide in corn cultivation, whose annual dosage is estimated up to 82 million pounds [6,7]. China has been the main producer and user for the past few decades, currently using 1000-1500 tons per year [8], Int. J. Environ.…”

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.
