As much as ca. 99.7% of the applied load of pesticides is dispersed in the environment, not reaching the target pests. In this way, pesticides enter into aquatic ecosystems from agricultural runoff or leaching and, as a ...

Paraquat toxic action on the freshwater microalga Chlamydomonas moewusii was determined by several physiological parameters. ATP content seems to be the most sensitive parameter analyzed; it was reduced by the lowest ...

The present study checked the suitability of the integration of flow cytometry (FCM) as technique and a freshwater microalga (Chlamydomonas moewusii) as cell system model for ecotoxicological studies, looking for sensitive ...

Aquatic environments are often contaminated with numerous organic and inorganic compounds. More than 90% of the applied load of pesticides is dispersed in the environment, reaching non-target species of these aquatic ...

[Abstract]The use of herbicides constitutes the principal method of weed control but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as microalgae. ...

An important amount of the applied load of pesticides enter into aquatic ecosystems from agricultural runoff or leaching and, as a consequence, have become some of the organic pollutants that appear most frequently on ...

Investigation of herbicide toxicology in non-target aquatic primary producers such as microalgae is of great importance from an ecological point of view. In order to study the toxicity of the widely used herbicide paraquat ...

[Abstract]Huge quantities of pesticides are dispersed in the environment, affecting non-target organisms. Since paraquat affects the photosynthetic process, the biochemical composition of affected species should be altered. ...

[Abstract] The use of herbicides constitutes the principal method of weed control, but the introduction of these compounds into the aquatic environment can provoke severe consequences for non-target organisms such as ...

Pulse discharges of chemicals to aquatic environments may lead to high concentrations of them in surface waters for short periods of time, but enough to induce toxic effects on aquatic organisms; however, no many methods ...
