(Universidade Federal de Minas GeraisUFMG, 2011-04-01)
The aim of this study was to essay sensivity in relation to two reference substances, sodium chloride (NaCl) and sodium dodecyl sulfate-SDS-(C12H25SO4Na) and water samples from Pampulha reservoir to Ceriodaphnia cornuta ...
Aquatic toxicity of ivermectin in cattle dung assessed using microcosms
(Academic Press Inc Elsevier Science, 2017-10)
Ivermectin (IVM) is a parasiticide widely used for livestock. It is a semisynthetic derivative of avermectin, a macrocyclic lactone produced by Streptomyces avermitilis. This drug is only partly metabolized by livestock; ...

Synergy between glyphosate and cypermethrin formulations on zooplankton: evidences from a single-specie test and a community mesocosm experiment
(Springer, 2021-01)
Agrochemicals can reach freshwater bodies by drift, leaching, or runoff, where they constitute complex mixtures. Given that glyphosate and cypermethrin are within the most worldwide used pesticides, they are likely to ...
Effects of glyphosate formulations on the population dynamics of two freshwater cladoceran species
(Springer, 2018-09)
The general objective of this work is to experimentally assess the effects of acute glyphosate pollution on two freshwater cladoceran species (Daphnia magna and Ceriodaphnia dubia) and to use this information to predict ...

Predator–prey imbalances due to a pesticide: density and applicability timing as determining factors for experimental assessments
(Springer, 2014-06)
Predator–prey relationships are determining factors in sustaining community structure but xenobiotics, including pesticides, have the potential to alter them, causing imbalances at the ecosystem level. Although invertebrate ...
