ORTIZ-GALLARZA, Silvia Margarita; HERNANDEZ LLAMAS, Alfredo  e  ORTEGA RUBIO, Alfredo. Diseño, construcción y aplicabilidad del Indice de Evaluación Ambiental de Ecosistemas Acuáticos (IEAEA). INCI [online]. 2005, vol.30, n.3, pp.126-133. ISSN 0378-1844.

An Aquatic Ecosystems Environmental Evaluation Index (EEAEI) was designed and developed, based on physicalchemical features and pollutant contents in water and sediments. Its applicability was verified. The quality criteria are supported by recent research information and legal limits, and pollutants which represent potential problems to public health and aquatic ecosystems are established. Principal Component Analysis and Sensitivity Analysis were used as validation techniques. The Sensitivity Analyses were developed in the extreme subindices and in the complete data set. EEAEI was applied to the results of 28 campaigns of Tehuantepec, Oaxaca, Mexico. Most indicators displayed statistical significance. The model is powerful and the values fluctuate around the median. It was demonstrated that it is sensible to climate variations, number of variables and number of data inputs; therefore, its applicability was verified.
