Removal of triazine herbicides from freshwater systems using photosynthetic microorganisms
González Barreiro, Óscar; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (2006-11)[Abstract]The uptake of the triazine herbicides, atrazine and terbutryn, was determined for two freshwater photosynthetic microorganisms, the green microalga Chlorella vulgaris and the cyanobacterium Synechococcus elongatus. ... -
Response of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments
Abalde, Julio; Cid, Ángeles; Reiriz, S.; Torres, Enrique; Herrero, Concepción (Springer, 1995-02)Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity ... -
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. ... -
Tolerance and detoxification mechanisms in marine diatom Phaeodactylum tricornutum exposed to cadmium
Torres, Enrique; Cid, Ángeles; Fidalgo Paredes, Pablo; Herrero, Concepción; Abalde, Julio (Springer, 1995)Tolerance is one of the most important mechanisms for survival. Organisms living in polluted environments with heavy metals develop tolerance to these contaminants; this tolerance has been attributed to the ability to ... -
Toxic action of copper on the membrane system of a marine diatom measured by flow cytometry
Cid, Ángeles; Fidalgo Paredes, Pablo; Herrero, Concepción; Abalde, Julio (WILEY-Liss, 1996-09)Flow cytometric measurements were used to investigate the toxic action of copper on some Phaeodactylum tricornutum membrane systems. Throughout the time of metal exposure, the percentage of viable cells decreased as copper ... -
Toxicidad del cobre sobre la diatomea marina Phaeodactylum tricornutum Bohlin
Cid, Ángeles (1993)[Resumen] EN ESTE TRABAJO HEMOS ANALIZADO LA RESPUESTA FISIOLOGICA DE LA DIATOMEA MARINA PHAEODACTYLUM TRICORNUTUM FRENTE A CONCENTRACIONES SUBLETALES DE COBRE. NUESTROS RESULTADOS INDICAN QUE LA TOXICIDAD DEL COBRE ... -
Toxicity induced by three antibiotics commonly used in aquaculture on the marine microalga Tetraselmis suecica (Kylin) Butch
Seoane, Marta; Rioboo, Carmen; Herrero, Concepción; Cid, Ángeles (Elsevier, 2014-10)Aquaculture facilities are a potential source of antibiotics to the aquatic ecosystems. The presence of these compounds in the environment may have deleterious effects on non-target aquatic organisms such as microalgae, ... -
Unravelling Joint Cytotoxicity of Ibuprofen and Oxytetracycline on Chlamydomonas Reinhardtii Using a Programmed Cell Death-Related Biomarkers Panel
Seoane, Marta; Conde-Pérez, Kelly; Esperanza, Marta; Cid, Ángeles; Rioboo, Carmen (Elsevier, 2023-02-24)[Abstract] Pharmaceutical active compounds (PhACs) are emerging contaminants that pose a growing concern due to their ubiquitous presence and harmful impact on aquatic ecosystems. Among PhACs, the anti-inflammatory ibuprofen ... -
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 ... -
Variations in planktonic bacterial biomass and production, and phytoplankton blooms off A Coruña (NW Spain)
Valencia, Joaquín; Abalde, Julio; Bode, Antonio; Cid, Ángeles; Fernández, Emilio; González, Nicolás; Lorenzo, Jorge; Teira, Eva; Varela, Manuel (CSIC, 2003)[Abstract] Bacterial abundance, biomass and heterotrophic activity, along with hydrographic and phytoplankton variables, were measured from February 1998 to September 1999 at two coastal stations off A Coruña (Galicia, ... -
Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured with different nutrient concentrations and urea as a nitrogen source
Herrero, Concepción; Abalde, Julio; Cid, Ángeles; Fidalgo Paredes, Pablo; Fábregas, Jaime (Station Biologique de Roscoff, 1994)[Abstract] Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured with different nutrient concentrations and urea as a nitrogen source. Cultures of the marine microalga ... -
