“…Similarly, DOM from two different sources, sludge and rice straw, at concentrations between 50 and 160 mg OC L -1 , promoted the mobility of chlortoluron (Song et al, 2008), prometryn (Jiang et al, 2008) or atrazine (Tian et al, 2019) using either soil thin-layer chromatographic plates or packed soil columns. These works suggest that the mobility of the herbicides in soil might be dependent on the sorption/desorption processes controlled by DOM.…”

“…Finally, a very recent study (Tian et al, 2019) investigated the uptake of atrazine by maize plants after treatment of the soil with DOM solutions derived from rice straw at 80 and 160 mg OC L -1 . In agreement with the above results DOM solutions also reduced the translocation of atrazine to the plant parts.…”

“…20−22 In the aquatic environment, for example, DOM combines with hydrophobic organic contaminants and affects their mobility. 23,24 Despite the fact that a growing number of investigations have been made on the behaviors of pesticides affected by DOM, 18,25,26 research on the interaction of DOM with propachlor in soil−water systems is still lacking. In this study, the batch equilibrium, thin-layer chromatography, column leaching, and bioaccumulation approaches were adopted to study the effect of DOM on the mobility of propachlor in the profile of soil−water−plant systems.…”

“…Triton X-100 (TX-100) is a kind of commonly used nonionic surfactant with the chemical formula of R–C 6 H 4 –(OC 2 H 4 )p–OH, where R is a branched octyl group and p is the average number of oxyethylene groups ( p ≈ 9.5) . It was found that the TX-100 supply in the subsurface of the soil elevated the level of residual contaminants, resulting in the delayed goal of clean-up. , On the other hand, the addition of nonionic surfactants into the soil can facilitate the biodegradation of contaminants. , Dissolved organic matter is a mixture of natural organic compounds, usually generated by well-decayed crop straw in farmland soil. The DOM complex is composed of carbohydrates, proteins, lignin, organic acids, and many other uncharacterized compounds and has some functional similarities to nonionic surfactants .…”

Propachlor is a widely used acylaniline herbicide for weeding annual gramineous and dicot plants in farmland. As a toxic agricultural chemical, it is overused in crop production and has become one of the most serious environmental pollutants. Yet, understanding the impact of environmental factors on its behavior in farmland soils is critically important for healthy crop production and food safety. In this study, we characterized the effect of dissolved organic matter (DOM) extracted from rice straw on the mobility behavior of propachlor in farmland soil using comprehensive approaches such as the batch equilibrium experiment, soil thin-layer chromatography, soil column leaching, and wheat bioaccumulation with Triton X-100 (TX-100) as a reference surfactant. The application of DOM at 60 and 120 mg DOC L–1 and TX-100 at 96, 192, and 288 mg L–1 reduced the sorption and increased the desorption of propachlor in soil. Freundlich constant K f values (sorption) of propachlor declined with the expansion of DOM and TX-100 concentrations. The addition of DOM and TX-100 increased the mobility of propachlor and the total concentration of propachlor in the leachate of soil columns. The retention factors (R f) were evaluated in the soil thin-layer chromatography as 0.741 and 0.772 (for DOM) and 0.731, 0.763, and 0.791 (for TX-100), all of which were greater than the control (0.710) under the treatment. The application of DOM or TX-100 reduced root growth (biomass) and increased bioaccumulation of propachlor in the roots and shoots of wheat. The outcome of the study can provide important references for the rational use of propachlor and help agronomic management to minimize pesticide contamination in realistic crop production.

“…What's more, TOC, clay properties, iron oxide content and pH value are the key parameters affecting the adsorption and desorption of atrazine in soil (Huang et al 2013). The application of dissolved organic matters and surfactants can reduce the adsorption and improve the desorption capacity of atrazine in soil (Tian et al 2019). However, atrazine exists in aquifers for a longer time than in soil, especially in quiet water, and the risk of accumulation is greater (Schwab et al 2006).…”

To study the influences of sand and gravel layer and groundwater velocity of Yufuhe River on atrazine migration, adsorption-desorption and sand column experiments were carried out. Results show that the adsorption capacity of montmorillonite, raw sand and washed sand to atrazine sequentially weakens. In different media, the time for atrazine concentrations to peak in washed sand with motomorillonite (WSM), raw sand and washed sand is 60, 135 and 105 minutes respectively, and the peak concentration accounts for 84, 90 and 95% of the initial concentrations. Under different flow rates, the peak time in washed sand at flow rates of 100, 150 and 200 mL/min is 135, 105 and 75 minutes, and the peak time in WSM is 90, 60 and 45 minutes, respectively. Results from this study indicate that increasing flow velocity and suspended colloids concentrations can promote the migration of atrazine in aquifers, while the presence of clay minerals in sand and gravel layer can reduce atrazine migration. Thus, during Yellow River water recharging, the sand and gravel layer of Yufuhe River is helpful to protect the aquifer, but the colloids-associated migration of atrazine can contaminate groundwater in underlying karst aquifer.
