Resumen
Se estableció la calidad del agua del río Babahoyo y sus afluentes dentro de la zona urbana, mediante la aplicación del índice de saprobio, determinando la composición y densidad del fitoplancton, presencia de organismos indicadores. Además se determinó las variables físico-químicas como la DBO5, OD, pH, temperatura, salinidad y nutrientes, para lo cual se realizó monitoreos durante el último trimestre del año 2011. La especie dominante fue Ulnaria ulna, fluctuando entre el 72,7 y 83,4 %; los porcentajes de esta dominancia se refleja en los valores obtenidos de diversidad absoluta que fueron inferiores a 2,9 bits.cel, valor considerado para aguas medianamente contaminadas en ecosistemas dulceacuícolas según el índice de Shannon y Weaver. Los valores obtenidos para la DBO5, OD, NH4 sobrepasaron los límites permisibles descritos en el TULAS, TULSMA y en otras normas internacionales establecidas, durante el mes de diciembre, y es reflejado en los resultados que indican presencia de contaminación orgánica débil en las estaciones correspondientes al puente El Salto, pero principalmente en el río San Pablo, represa La Ventura debido a el material orgánico liberado por las piladoras del sector, siendo necesario plantear medidas de control.
Settled the water quality of the Babahoyo River and its tributaries within the urban area, through the application of the saprobic index, determining the composition and density of phytoplankton as indicators organisms. In addition, physiochemical variables as the DB05, 0D, pH, temperature, salinity and nutrients, was determined during the last quarter of the year 2011. The dominant species was Ulnaria ulna fluctuating between the 72.7 and 83.4%; the percentages of this dominance is reflected in absolute diversity values that were lower than 2.9 bits per cell value considered for moderately polluted water into wetland ecosystems according to the index of Shannon and Weaver. The values obtained for the DB05, 0D, NH4 exceeded allowable limits described in the TULAS, TULSMA and other international standards established during the month of December, and it is reflected in the results indicating presence of organic pollution weak stations corresponding to the El Salto bridge, but mainly in the River San Pablo dam La Ventura due to the organic material released by the rice peelers of the sectorstill necessary to consider measures of control
