Comparación de la calidad del agua en dos ríos altoandinos mediante el uso de los índices BMWP/COL. y ABI.

Abstract

Se comparó la calidad ecológica del río Tota durante agosto 2007 y febrero 2008, y el curso alto del río Bogotá entre los meses de octubre 2013 y enero 2014, aplicando los índices BMWP/Col y ABI. Los puntos de muestreo corresponden a la parte alta, media y baja del gradiente longitudinal. En el río Tota se determinaron 27 familias correspondientes a 11 órdenes, donde las más abundantes fueron Baetidae (25,43 %), Leptohyphidae (16,43 %), Naididae (13,76 %), Chironomidae (11,42 %) y Hyalellidae (10,30 %). En el curso alto del río Bogotá se determinaron 32 familias correspondientes a 13 órdenes, y las más abundantes fueron Chironomidae (28,94 %), Leptoceridae (25,20 %), Naididae (18,34 %) y Simuliidae (8,63 %). En el río Tota, El BMWP/Col. presentó una calidad de agua buena, mientras que el ABI presentó una calidad aceptable. Por otra parte, en la parte alta del Río Bogotá, tanto el BMWP/Col. como el ABI presentaron variaciones en la calidad del agua entre aceptable y muy crítica. El ACC para el río Tota mostró correlaciones entre la temperatura y conductividad con las familias Hyalellidae y Leptohyphidae mientras que el caudal se relaciona Sphaeriidae. Mientras que el curso alto del río Bogotá se correlacionó el caudal, conductividad y temperatura con la familia Veliidae. A manera de conclusión, los resultados obtenidos denotan que el índice ABI, que es un índice creado para sistemas andinos de montaña, es más sensible a los impactos que el índice BMWP/Col.

Water quality assessment methods of the highland Andean rivers: A scoping systematic review

“…However, in this context, some indexes based on bioindicators proposed by different developed countries but adapted to different South American countries, an evident lack can be reflected among them, as pointed out in the study by Carrasco-Badajoz, C. [ 67 ], where there are differences between the BMWP-Col, ABI, and EPT indices, where he finds errors between them in their water quality results, which in the same way is mentioned by Meneses-Campo, Y et al [ 70 ], where he concludes that despite using the adapted indices such as BMWP-Col and ABI, he finds the latter more sensitive for the analysis of water quality of two Colombian rivers, reflecting more accurate results. On the other hand, Pimentel, HF et al [ 72 ] attribute better water quality assessment characteristics using the ABI index than the EPT index.…”

Water quality according to the WQI in the rural sectors was qualified as good quality water and in 67 % of the urban sectors, as poor-quality water 9 SC Meneses-Campo, Y. et al [ 70 ] Comparison of Water Quality Between Two Andean Rivers by Using the BMWP/COL. and ABI.…”

Benthic macroinvertebrate communities and water quality assessment in high Andean Wetlands Callali-Oscollo, Arequipa-Cusco, Peru

“…The ABI has proved to be efficient in evaluations of high Andean rivers above 2,000 m asl and areas with anthropic influence. The ABI has been applied in Colombia, Ecuador and Peru (Meneses-Campo et al, 2019).…”

Description of the primary Loreto-coca river contamination through the measurement of physicochemical parameters

“…The possibility of using microalgal biomass as a bioremediation agent for the purification of water contaminated with PM (Particulate matter) has demonstrated the effectiveness of four green microalgae species (Chlamydomonas reinhardtii, Chlorella vulgaris, Scenedesmus almeriensis and Chlorophyceae sp., isolated from the Loa River). These biological purification processes on the elements As, B, Cu, Mn and Zn, present in aqueous solutions, gave us good results by analyzing the operation factors and integration processes 25 .…”
