Acute glyphosate exposure does not condition the response of microbial communities to a dry-rewetting disturbance in a soil with long history of glyphosate-based herbicides
(Copernicus, 2020-07-15)
Dry-rewetting perturbations are natural disturbances in the edaphic environment and particularly in dryland cultivation areas. The interaction of this disturbance with glyphosate-based herbicides (GBHs) deserves special ...
Acute and chronic toxicity of glyphosate to native fish from San Luis province, Argentina
(Research Trends, 2015-07)
Public concern on the risks of glyphosate exposure has risen in Argentina, where glyphosate is used massively. Fish are widely used as models to assess the effects of contaminants. In this study we estimated the toxic ...
Synergy between glyphosate- and cypermethrin-based pesticides during acute exposures in tadpoles of the common South American Toad Rhinella arenarum
(Elsevier, 2014-04)
The herbicide glyphosate and the insecticide cypermethrin are key pesticides of modern management in soy and corn cultures. Although these pesticides are likely to co-occur in ephemeral ponds or aquatic systems supporting ...
Exposure to Roundup® affects behaviour, head regeneration and reproduction of the freshwater planarian Girardia tigrina
(Elsevier, 2019)
The demand of glyphosate-based herbicides including Roundup(R) is rising in the tropics due to increase occurence of glyphosate-resistant weeds that require higher herbicide application rates but also because of their use ...
Acute uterine effects and long-term reproductive alterations in postnatally exposed female rats to a mixture of commercial formulations of endosulfan and glyphosate
(Pergamon-Elsevier Science Ltd, 2019-09)
Endosulfan and glyphosate are widely used pesticides and have been associated toreproductive disorders. We examine the acute and long-term effects of postnatal exposure to commercial formulations of endosulfan (EF), ...
Glyphosate as an acetylcholinesterase inhibitor in Cnesterodon decemmaculatus
(Springer, 2012-01)
The toxic effect of sublethal concentrations (1, 17.5 and 35 mg L -1) of pure glyphosate was evaluated on acetylcholinesterase (AChE) activity in the fish species, Cnesterodon decemmaculatus. Acute bioassays (96 h) under ...
Ecotoxicologia do glifosato e surfactante aterbane® br para guaru (Phalloceros caudimaculatus)
(2010-10-15)
Aquatic macrophytes are important components of aquatic ecosystems, but these plants have become a problem due to their occurrence in different regions. Some studies aimed to demonstrate the effectiveness of herbicides to ...

Cortisol response to acute stress in jundiá Rhamdia quelen acutely exposed to sub-lethal concentrations of agrichemicals
(2008-09-01)
Exposure to agrichemicals can have deleterious effects on fish, such as disruption of the hypothalamus-pituitary-inter-renal axis (HPI) that could impair the ability of fish to respond to stressors. In this study, fingerlings ...
