Algae capable of affecting sanitary conditions in water reservoirs of the Central-Western Region of the province of Cordoba, Argentina

Algae populations in artificial water reservoirs have a dramatic impact, particularly on the process of eutrofication. Eutrofication causes continuous change in phytoplanktonic communities, increasing the frequency and density of cyanobacteria that take the place of Diatomea, Chlorophyceae and Dinof...

description Algae populations in artificial water reservoirs have a dramatic impact, particularly on the process of eutrofication. Eutrofication causes continuous change in phytoplanktonic communities, increasing the frequency and density of cyanobacteria that take the place of Diatomea, Chlorophyceae and Dinoflagellates. The main problem associated to cyanobacteria is the emergence of toxic strains which can affect human health, domestic animals and the water ecosystem at large. Cyanobacteria biotoxins are among the most powerful poisons known. The aim of this project is to survey the reservoirs known as San Roque, La Quebrada, La Falda and El Cajón with a view to identifying the main types of algae capable of affecting sanitary conditions.For the taxonomic study of the species, the specific codes and identification manuals will be followed. Sample count shall be done using the direct count technique employing a photonic microscope. Though emphasis will be on Cyanophyceae, other taxons shall be studied as well because of their sanitary importance, their interaction with the latter or their abundance, such as Euglenophyceae, Cloropyceae, Bacillariophyceae, Dinophyceae and other groups.Out of a total number of 80 species found, the 10 are of sanitary importance comprise two groups: a) Toxing-generating algae (hepatotoxic and neurotoxic) such as Microcystis aeruginosa, Oscillatoria sp, and Anabaena. b)Algae that can give water various tastes and odors such as Ceratium hirundinella, Peridinium sp.,Euglena sp., Aulacoseira granulata, Cyclotella meneghiniana, Carteria sp., and Closterium acicularis.Algae populations in water supply reservoirs entail risks for the health of the communities being served, through the growth of toxic species, transfer of unpleasant tastes and odors and possible formation of trihalomethanes.

Las floraciones algales en embalses artificiales producen profundas modificaciones relacionadas especialmente con el proceso de eutroficación. La eutroficación lleva a continuos cambios en las comunidades fitoplántónicas, aumentando las frecuencias y densidades de cianobacterias que desplazan a las diatomeas, clorofíceas y dinoflagelados. El problema más importante relacionado con las cianobacterias es la aparición de cepas tóxicas y sus consecuencias sobre la salud humana, animales domésticos y sobre el ecosistema acuático en general. Las biotoxinas de las cianobacterias se las ha clasificado dentro de los venenosos más poderosos que se conocen. El objetivo del presente trabajo es realizar un monitoreo del embalseSanRoque, La Quebrada, La Falda y El Cajón a los fines de identificar las principales algas de interés sanitario que puedan afectar a la salud.El estudio taxonómico de las especies se realizará siguiendo las claves y manuales de identificación específicos. El recuento de las muestras se realizará por conteo directo, mediante microscopía fotónica. Si bien se pondrá énfasis en la determinación de Cianofíceas, se incluirá también el estudio de algunos otros taxones de importancia sanitaria o por sus interacciones con las primeras o por su abundancia, tales como Euglenofíceas, Clorofíceas, Bacillariofíceas, Dinofíceas y otros grupos.De un total de aproximadamente 80 especies encontradas, 10 de ellas resultan de importancia sanitaria, dividiéndolas en dos grupos: a) Algas que pueden producir toxinas (hepatotóxicas y neurotóxicas) como Microcystis aeruginosa, Oscillatoria sp, y Anabaena. b) Algas que pueden transmitir al agua diferentes olores y sabores comoCeratium hirundinella, Peridinium sp., Euglena sp., Aulacoseira granulata, Cyclotella meneghiniana, Carteria sp.,y Closterium acicularis.Los florecimientos algales en reservorios de agua para abastecimiento representan un riesgo para la salud de las poblaciones abastecidas, debido a la aparición de especies tóxicas, transferencia de olores y sabores desagradables, y posible formación de trihalometanos.
