“…As illustrated by Kim et al (2011b), ATZ may experience altered decomposition rates and pathways when VAs are present in soil. Atrazine is the most prevalent triazine herbicide used in the United States for controlling broadleaf weeds (Thelin and Stone, 2013), and microbial degradation is the primary means of ATZ dissipation in soil (Mandelbaum et al, 1993;Ostrofsky et al, 2002;Lin et al, 2008).…”

“…Accinelli et al (2006) found that μg kg −1 concentrations of the VA sulfamethazine [SMZ; 4‐amino‐N‐(4,6‐dimethylpyrimidin‐2‐yl)‐benzenesulfonamide] in sandy loam soil had no apparent influence on metolachlor degradation or sorption. Kim et al (2011b) found that atrazine [ATZ; 6‐chloro‐N‐ethyl‐N′‐(1‐methylethyl)‐triazine‐2,4‐diamine] concentrations in sand treated with the VAs monensin, narasin, and salinomycin were significantly greater and ATZ half‐lives were significantly longer compared with control treatments. Two other studies using soil of varying textures found reduced herbicide degradation in soils sterilized using elevated concentrations and repeated antibiotic applications (Levanon, 1993; Ostrofsky et al, 2002).…”

Veterinary antibiotics (VAs) in manure applied to agricultural lands may change agrichemical degradation by altering soil microbial community structure or function. The objectives of this study were to investigate the influence of two VAs, sulfamethazine (SMZ) and oxytetracycline (OTC), on atrazine (ATZ) degradation, soil microbial enzymatic activity, and phospholipid fatty acid (PLFA) markers. Sandy loam soil with and without 5% swine manure (w/w) was amended with 0 or 500 μg kgC radiolabeled ATZ and with 0, 100, or 1000 μg kg SMZ or OTC and incubated at 25°C in the dark for 96 d. The half-life of ATZ was not significantly affected by VA treatment in the presence or absence of manure; however, the VAs significantly ( < 0.05) inhibited ATZ mineralization in soil without manure (25-50% reduction). Manure amendment decreased ATZ degradation by 22%, reduced ATZ mineralization by 50%, and increased the half-life of ATZ by >10 d. The VAs had limited adverse effects on the microbial enzymes β-glucosidase and dehydrogenase in soils with and without manure. In contrast, manure application stimulated dehydrogenase activity and altered chlorinated ATZ metabolite profiles. Concentrations of PLFA markers were reduced by additions of ATZ, manure, OTC, and SMZ; adverse additive effects of combined treatments were noted for arbuscular mycorrhizal fungi and actinobacteria. In this work, the VAs did not influence persistence of the ATZ parent compound or chlorinated ATZ metabolite formation and degradation. However, reduced CO evolved from VA-treated soil suggests an inhibition to the degradation of other ATZ metabolites due to an altered soil microbial community structure.

“…Without any intervention to reduce their bioaccessibility, these antibiotics can remain active in the soil and influence the presence of antibiotic-resistant bacteria (Kemper, 2008). Active antibiotics in the soil are capable of reducing soil microbial populations (Kim, Fan, Prasher, Patel, & Hussain, 2011). Therefore, if antibiotics and herbicides are both present in a soil matrix without any soil amendment intervention, herbicide degradation could be hindered if soil microbial populations that are responsible for herbicide degradation are reduced.…”

The aim of this study was to determine the effects of biochar addition on agrochemical leaching in tropical soils of Belize. Biochars were produced from mixed softwood, rice husk and miscanthus straw, each pyrolysed at 700 C. Loam, sandy silt loam and clay loam tropical soils were amended with 0, 1, 2.5 and 5% (w/w) biochar to determine atrazine, diuron, enrofloxacine, oxytetracycline and tetracycline absorption in batch studies following OECD 106 guidelines. FOCUS groundwater modelling was performed with the results of the batch-sorption study and alterations to the soil profiles to explore the effect of biochar amendment on the leaching of atrazine in a risk assessment context. Results showed that agrochemical sorption was higher in biochar-amended soils than soils without biochar amendment. Soil organic matter content and biochar amendment contributed to the agrochemical sorption increase in soils. The FOCUS modelling showed a significant reduction in predicted environmental concentration in groundwater (PECgw) of atrazine when biochar was applied as a soil amendment. However, a trade-off was identified between the sorptive capacity of the biochar and the changes in hydrology in the soil as a result of the biochar incorporation. The amendment of Belizean tropical soils with rice husk biochar was shown to be an effective method to reduce the leaching of the selected agrochemicals, although widespread implementation should be conducted carefully, taking account of the potential trade-offs with biochar use identified in our modelling. Highlights • Biochar-amended soil is a feasible method to increase sorption and reduce agrochemical leaching to groundwater.• Environmental fate modelling demonstrated that 1% and 2.5% biochar amendment could reduce atrazine leaching in soil.• Modelling identified a biochar performance trade-off: altered soil hydrology could lead to greater leaching.• Biochar implementation must account for trade-offs identified to ensure the mitigation works in each circumstance.

“…Por ejemplo, algunos elementos se volatilizan hacia la troposfera, ya sea por degradación química o microbiana, cuyos metabolitos no necesariamente son inocuos para la biosfera (López-Geta et al, 1992). Uno de los herbicidas más empleado en la agricultura mexicana es la atrazina, C8H14ClN5 (CAS: 1912-24-9, 6-cloro-N-etil-N-isopropil-1,3,5-triazina-2,4-diamina, que se caracteriza por actuar a nivel sistémico y ser de amplio espectro (Kim et al, 2011). Se utiliza para el control emergente de arvenses de hoja ancha y pastos, actúa por vía radical (rizosfera) y se acumula en las hojas impidiendo la fotosíntesis de las plantas (Márquez et al, 2009).…”

La contaminación de aguas superficiales y subterráneas por herbicidas como la atrazina ocurre por lixiviación a través del perfil del suelo. El objetivo del estudio fue evaluar la movilidad de atrazina en parcelas dedicadas al cultivo de maíz, cada una con un tipo de suelo distinto ubicadas en los municipios de San Nicolás Buenos Aires (Regosol) y Los Reyes de Juárez (Calcisol), Puebla, México. Se realizaron experimentos de desplazamiento en columnas empacadas de suelo (8.5 cm de diámetro y 30 cm de longitud). Sobre cada columna se aplicó una concentración acuosa de 6.25 g L-1 de atrazina (Gesaprim®). Se empleó, primero, un volumen de poro de una solución reconstituyente del suelo (sin atrazina) y posteriormente, se aplicaron 30 volúmenes de poro de agua de riego que contenía atrazina. Se analizaron los lixiviados y tres profundidades de las columnas de suelo (0-2 cm, 2-10 cm y 10-20 cm, respectivamente). Los resultados de correlación de Pearson mostraron que la materia orgánica, textura y la capacidad de intercambio catiónico fueron las características fisicoquímicas del suelo que afectan a la movilidad de la atrazina. La atrazina presentó un coeficiente de retardo de 1.08 en Regosol y de 1.03 en Calcisol. El transporte del herbicida fue nueve veces mayor velocidad en el Regosol con respecto al Calcisol. La atrazina se mantuvo retenida en una mayor cantidad en los dos centímetros de las columnas de suelo. El porcentaje de masa degradada de atrazina fue de 94% para el Regosol y 69% para el Calcisol.
