Alteration of photosynthesis related parameters of Chlamydomonas moewusii stressed by paraquat
Cid, Ángeles; Franqueira, Dolores; Rioboo, Carmen; Prado, Raquel; Herrero, Concepción (Research Trends, 2008)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 ... -
Cell proliferation alterations in Chlorella cells under stress conditions
Rioboo, Carmen; O’Connor, José Enrique; Prado, Raquel; Herrero, Concepción; Cid, Ángeles (2009-09)[Abstract]Very little is known about growth and proliferation in relation to the cell cycle regulation of algae. The lack of knowledge is even greater when referring to the potential toxic effects of pollutants on microalgal ... -
Characterization of cell response in Chlamydomonas moewusiicultures exposed to the herbicide paraquat: Induction of chlorosis
Prado, Raquel; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (2011-03)[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 ... -
Comparison of the sensitivity of different toxicity test endpoints in a microalga exposed to the herbicide paraquat
Prado, Raquel; García Díaz, Rosa; Rioboo, Carmen; Herrero, Concepción; Abalde, Julio; Cid, Ángeles (2009-02)[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. ... -
Cytotoxic effects of pesticides on microalgae determined by flow cytometry
Rioboo, Carmen; Prado, Raquel; Herrero, Concepción; Cid, Ángeles (Nova Science Publishers, 2009)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 ... -
Flow cytometric analysis to evaluate physiological alterations in herbicide-exposed Chlamydomonas moewusii cells
Prado, Raquel; Rioboo, Carmen; Herrero, Concepción; Suárez-Bregua, Paula; Cid, Ángeles (Springer, 2012-03)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 ... -
Population growth study of the rotifer Brachionus sp. fed with triazine-exposed microalgae
Rioboo, Carmen; Prado, Raquel; Herrero, Concepción; Cid, Ángeles (2007-08)[Abstract]Few data exist on potential toxic effects that pollutants may have on zooplankton fed microalgae exposed to pesticides. For that reason, microalgal cultures were exposed to different concentrations of the triazine ... -
Screening acute cytotoxicity biomarkers using a microalga as test organism
Prado, Raquel; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (Elsevier, 2012-12)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 ... -
Suitability of cytotoxicity endpoints and test microalgal species to disclose the toxic effect of common aquatic pollutants
Prado, Raquel; García Díaz, Rosa; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (Elsevier, 2015-04)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 ... -
The herbicide paraquat induces alterations in the elemental and biochemical composition of non-target microalgal species
Prado, Raquel; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (2009-09)[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. ... -
Use of Microalgae as Biological Indicators of Pollution: Looking for New Relevant Cytotoxicity Endpoints
Cid, Ángeles; Prado, Raquel; Rioboo, Carmen; Suárez-Bregua, Paula; Herrero, Concepción (Nova Science Publishers, 2012)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 ... -
Use of the Comet Assay to Evaluate Pesticide Toxicity on Non-Target Microalgae
Prado, Raquel; García Díaz, Rosa; Rioboo, Carmen; Abalde, Julio; Herrero, Concepción; Cid, Ángeles (Nova Science Publishers, 2009)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 ...
