Evaluacion de la calidad de agua mediante un analisis multivariante en los esteros del Golfo de Fonseca, Honduras.
Summary
Researchers analyzed water quality data from eight monitoring sites in the Gulf of Fonseca esteros in Honduras (2000-2015) using principal component analysis and cluster analysis, identifying three significant water quality groups with nitrogen, phosphorus, BOD, and alkalinity explaining the greatest variance as indicators of poor water quality.
Se recopilaron datos de calidad de agua de ocho sitios de monitoreo que incluyo 7 parámetros entre 2000-2015. Para el análisis de datos se utilizaron estadísticas descriptivas, análisis de componentes principales (ACP) y de conglomerados. El ACP resulto en 3 componentes que explicaron el 72,6% de la varianza total. El primer componente incluyo Nitrógeno total, Fosforo total, Demanda Bioquímica de Oxígeno (DBO5) y alcalinidad representando mala calidad de agua. El segundo componente incluyo salinidad y pH representando calidad de agua moderada. El tercer componente representa la contaminación por solidos sedimentables. Como resultado del análisis de conglomerados, se clasificaron tres grupos estadísticamente significativos, el grupo I esteros Purgatorio y Barrancones con calidad de agua buena, grupo II esteros Garcero, San Bernardo, Pedregal, Perejil y Berbería calidad de agua mala, y grupo III estero Jagua calidad de agua moderada. Los análisis indicaron que los esteros con mala calidad de agua fueron los sitios que han aumentado las actividades antropogénicas directamente por aguas residuales de acuicultura. Es necesario tomar medidas preventivas que propicien el desarrollo de la vida acuática a través de la orientación de una regulación y servicio costero efectivo en la que se apoyen los esfuerzos de gestión en el futuro.

Water Quality Assessment of Inland Waters in Cartagena de Indias – Colombia, Using Multivariate Statistics
Researchers assessed water quality in four inland water bodies in Cartagena de Indias, Colombia over the period 2008-2022, analyzing parameters including dissolved oxygen, BOD, COD, total coliforms, chlorophyll, and total phosphorus using descriptive and multivariate statistical methods to characterize long-term pollution trends in urban coastal waters.
Variations of surface water quality in selected tidal creeks of Sagar Island, Indian Sundarban eco-region: a multivariate approach
Researchers monitored water quality in tidal creeks of India's Sundarbans mangrove region for a full year, finding that salinity, turbidity, and dissolved oxygen varied most dramatically across seasons and were heavily influenced by monsoon runoff and boat traffic. The baseline data provides a foundation for managing water quality in this ecologically sensitive and biologically rich estuary.
Water Quality Analysis and Its Impact on Biodiversity in Freshwater Ecosystems
Researchers measured physicochemical water quality parameters and biological communities at five freshwater sites with varying degrees of anthropogenic disturbance, using correlation analysis, PCA, and cluster analysis to link water quality to aquatic biodiversity. They found strong positive correlations between dissolved oxygen and species richness, and significant negative associations between BOD, nitrate, heavy metals, and biodiversity, concluding that degraded water quality directly compromises freshwater ecosystem function.
