Although the study of physicochemical characterization of Urmia Lake confirms the salinity of lake is changing but this study has focused on the pattern of Weight-Frequency Percentage (%WF) form 1852 to 2008. Reanalysis of last data showed %WF hasn’t had homogenous structure of Weight-Frequency P...
A study was done on the quality of the waters of the rivers Amargos and Niblinto and their effluents in the Malleco National Park-Chile. The water flows studied are of ritral type, have high slope, low water flow, high speed, low temperature and highly oxygenated waters. Six sampling points were ...
A follow-up in 2013 of the indicators of pollution (temperature, hydrogen potential, salinity, dissolved oxygen, ammonium, nitrites, nitrates, orthophosphates, ortho silicates, biological oxygen demand, chemical oxygen demand, suspended solids) in surface water was performed, in order to estimate...
Present work was pertaining to studies conducted at one lentic perinial water body at Talaguppa viz., Gourikere pond Tq:Sagar Karnataka. The period of study undertaken it one year from May - 2007 to April - 2008. This study is intended to monitor the water quality of Gourikere pond of Talaguppa, ...
Macroinvertebrates have been used for decades to evaluate water quality, using measures of diversity, biotic indexes and comparative analysis. The taxonomic level of family allows a general interpretation of the ecological quality of a fluvial system, and is possible to infer the quality of these...
Los macroinvertebrados han sido utilizados por décadas para evaluar la calidad de las aguas, utilizando medidas de diversidad, índices bióticos y comparativos, sugiriendo que el nivel taxonómico de familia permite una buena interpretación general de la calidad ecológica de un sistema fluvial y es...
En el presente trabajo se elaboró una propuesta de plan de vigilancia, para la Norma Secundaria de Calidad Ambiental para la cuenca del río Itata, la cual incorpora a la normativa nacional de recursos hídricos el ámbito ecológico. Utilizando la información disponible en la base de datos de CONAMA...
This work was developed proposed monitoring plan for High Quality Standard Environmental Itata River basin, which incorporates the rules the national water ecological environment. Using information available in the database and DGA is Biobío CONAMA conducted a spatial analysis of the monitoring n...
Temperature drives the major physico-chemical and biological actions in inland water bodies. The higher the water temperature, the greater the biogeochemical activity influenced by the environmental intrinsic and extrinsic parameters. Temperature also controls the dynamics of sustainability of va...
La cuenca del estero Nonguén es un ejemplo de la realidad que se observa en la mayoría de las cuencas localizadas en zonas urbanas, debido al alto grado de intervención que presenta en su parte baja, influenciada por el constante aumento de la alta densidad poblacional. Sin embargo, en su parte a...
The water quality in the upper and medium zone of Traiguén river in the Araucanía region was studied in the present work. Physico-chemical and microbiological parameters were measured at six sample stations in a zone that goes from close to the origin of the river to the limits of the city of Vic...
