“…Lolium multiflorum can increase atrazine, chlorpyrifos and pentachlorophenol removal (He et al, 2008;Merini et al, 2009;Urrutia et al, 2013a). Singh et al (2004) demonstrated that the Pennisetum clandestinum The aim of the present work was to evaluate the effect of the rhizosphere of a biopurification system on the dissipation of a pesticide mixture.…”

In a biopurification system such as a biobed, the rhizosphere of the grass layer may be a significant factor for promoting pesticide dissipation in the biomixture. The rhizosphere effect of a Lolium perenne, Festuca arundinacea and Trifolium repens mixture on the dissipation of a pesticide combination that was composed of atrazine, chlorpyrifos and isoproturon was studied. The assay was performed using glass pots divided into two separate compartments (root surface and root-free), each filled with an organic biomixture (oat husk, top soil and peat) and contaminated with the pesticide mixture at 5 mg kg -1 . Non-planted and noncontaminated pots were also used as controls. The results indicated that there were high atrazine, chlorpyrifos and isoproturon dissipation in the planted pots compared with the unplanted pots. An inverse correlation was found throughout the assay between phenoloxidase activity and residual pesticide (r=0.684 to 0.952). Indeed, fungal biomass was positively correlated with phenoloxidase activity on day 1 (r =0.825) and day 30 (r =0.855). Besides, exudation of oxalic and malic acid in contaminated pots was higher than in the control without pesticides, associated with oxidation of the pesticide mixture in the biomixture of a bioded system. Therefore, the grass layer enhances pesticide removal in biobeds.

“…For instance, in the USA, almost 30,000 t of atrazine are applied annually (Hase et al 2008). Because of its intense use, stability and ability to translocate in the environment (Roustan et al 2014;Yixin et al 2014;Nachimuthu et al 2016), atrazine is present in soils and waters worldwide (Hase et al 2008;Merini et al 2009;Feria-Reyes et al 2011;Li et al 2012;Farlin et al 2013;Geng et al 2013;Ji et al 2015;Ouyang et al 2016a). Atrazine is suspected to be an endocrine disruptor and is linked to Parkinson's disease in humans (Filipov et al 2007;Brodeur et al 2009).…”

Purpose In this paper, an attempt was made to explain the long-lasting occurrence of atrazine in soil. Despite the fact that this herbicide has been banned in European Union 10 years ago, it is still detected in the environment. Materials and methods Soil samples (organic and mineral horizon), SiO 2 and Al 2 O 3 sorbents were spiked with atrazine. The ultrasound-assisted extraction coupled with gas chromatography-electron capture detector was performed to establish the atrazine recovery depending on the type of soil horizon and sorbent. Fourier transform infrared spectroscopy (FTIR) analysis was conducted to determine the type of interactions between atrazine and sorbents. Results and discussion The atrazine recovery was lower for the mineral horizon (15%) compared to the organic horizon (63%). This finding suggests an interaction between atrazine and the mineral components of soil. Therefore, attempts have been made to explain atrazine's interaction with the main mineral components of soil, SiO 2 and Al 2 O 3 , and to investigate the influence of pH on atrazine's behaviour in soil. The atrazine recoveries were 86.5 and 10.7% for Al 2 O 3 and SiO 2 , respectively. The obtained results demonstrated that the protonated atrazine exhibits stronger interactions with the soil mineral layer (recovery below 0.1%) in comparison to molecular form of atrazine (recovery 86%). FTIR results suggested interactions between atrazine and SiO 2 . FTIR analysis revealed that 1,3,5-azidine ring interacts with SiO 2 molecule. Conclusions In acidic soil, atrazine remediation is limited, especially if the soil contains minerals with high SiO 2 contents. This situation may cause the long-lasting persistence of atrazine in soil.

“…The cytochrome P450 system is one of the most important enzymatic pathways for detoxification of xenobiotics in monocots (including rice) and has been described as a common atrazine tolerance mechanism (Burnet et al, 1993;Marcacci et al, 2006). In addition, the atrazine hydroxylation may occur partly due to the production of benzoxazinones, which are synthesized by CYP71 family P450 enzymes and are considered as defense substances against bacteria in crops such as corn and sorghum (Bailey and Larson, 1991;Merini et al, 2009). However, the mono N-dealkylation products of atrazine are partially detoxified, while the double dealkylated and hydroxylated products have no phytotoxicity towards plants (Shimabukuro, 1968).…”
