Resumen El objetivo fue evaluar la fitotoxicidad de un formulado comercial de glifosato (sal potásica al 62%, equivalente a 506 g p.a./L) sobre Lemna gibba, a campo y en laboratorio. El estudio a campo se desarrolló en un embalse asociado a un ambiente agrícola. Allí se realizó un análisis temporal, con observaciones en cuatro momentos

Abstract Cypermethrin (CM), widely used for control of indoor and field pests, is one of the most common contaminants in freshwater aquatic systems. We evaluated CM genotoxicity and the activities of superoxide dismutase (SOD) and catalase (CAT) in retinal cells of adult zebrafish. Histological and immunofluorescence techniques show the presence of apoptotic cells in the

Abstract Cypermethrin (CYP) is a synthetic pyrethroid insecticide, used to control pests in domestic, industrial and agricultural environments. According to recent reports, it is one of the most common contaminants in freshwater aquatic systems. The aim of this study was to evaluate its potential genotoxic effect and the activation of the superoxide dismutase (SOD) and

Abstract Superoxide dismutase (SOD) is an antioxidant enzyme that acts as a component of first-line defense system against reactive oxygen species (ROS). Copper/Zinc superoxide dismutase (Cu/Zn-SOD) is one of the isoforms of SOD enzyme and is sensitive to the exposure of different environmental factors, in different species and tissues. Caiman latirostris is one of the

Abstract The safety of creating fish farms in agricultural settings was evaluated by growing Piaractus mesopotamicus in a pond, while crops where cultivated in a nearby field under a pesticide application regime typical of the Pampa region. Atrazine, glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), were detected in the water of the pond at concentrations

Abstract The quantitative real-time polymerase chain reaction (qPCR) has been one of the most promising approaches to perform rapid and accurate quantification of DNA in various biological systems. The aim of this study was to standardized the qPCR technique for the analysis of important genes involved in the main routes of antioxidant defense against reactive

Abstract Lead (Pb) is a non-essential, highly toxic, and persistent element widely recognised as one of the most concerning pollutants, and it is listed in the Priority List of Hazardous Substances. Widespread environmental contamination from Pb is a serious issue for human health and wildlife. The liver, a key compartment for metal detoxification and excretion,
