Abstract
El presente estudio se enfoca en la evaluación de la calidad del agua en tres cuencas
hidrográficas del norte del Perú mediante la aplicación del índice biótico nPeBMWP. Se
empleó un tiempo de muestreo de aproximadamente una hora, recolectando alrededor de 100
individuos, se optó por el método de barrido debido a su simplicidad y utilidad en estudios
de calidad biológica. Los resultados del monitoreo revelaron una relación entre la presencia
de ciertas familias de macroinvertebrados y la calidad del agua en las cuencas estudiadas. La
abundancia de taxones indicadores de buena calidad del agua se asoció con estaciones con
condiciones ecológicas favorables, mientras que otros indicadores sugirieron niveles de
afectación por factores como la actividad minera.
Se observó que la distribución de los puntos de muestreo y la georreferenciación de los
mismos permitieron establecer una relación entre la calidad del agua y factores como la
actividad minera. Se identificaron cambios en la composición taxonómica de los
macroinvertebrados en función de la calidad del agua, con presencia significativa de especies
indicadoras de contaminación en áreas cercanas a actividades antropogénicas.
En conclusión, se evidencia una relación directa entre la presencia de ciertos
macroinvertebrados y la calidad del agua, lo que sugiere la utilidad de los índices bióticos
en especial la nPeBMWP dado que está adaptada a los ríos del norte del país como
herramienta de monitoreo los resultados indican que la calidad del agua en las cuencas
estudiadas, además la calidad del agua está influenciada por actividades antropogénicas,
especialmente la minería. Estos hallazgos subrayan la importancia de implementar medidas
de gestión y conservación para mitigar los impactos negativos sobre los recursos hídricos en
la región.
The present study focuses on evaluating water quality in three hydrographic basins in northern Peru through the application of the nPeBMWP biotic index. A sampling time of approximately one hour was employed, collecting around 100 individuals. The sweep method was chosen due to its simplicity and usefulness in biological quality studies. Monitoring results revealed a relationship between the presence of certain macroinvertebrate families and water quality in the studied basins. The abundance of taxa indicating good water quality was associated with stations exhibiting favorable ecological conditions, while other indicators suggested levels of impact due to factors such as mining activity. The distribution of sampling points and their georeferencing allowed for establishing a relationship between water quality and factors such as mining activity. Changes in the taxonomic composition of macroinvertebrates were identified based on water quality, with a significant presence of pollution indicator species in áreas near anthropogenic activities. In conclusion, a direct relationship is evident between the presence of certain macroinvertebrates and water quality, which suggests the usefulness of biotic indices, especially the nPeBMWP, given that it is adapted to the rivers in the north of the country as a tool for monitoring the results. indicate that the quality of the water in the studied basins, in addition the quality of the water is influenced by anthropogenic activities, especially mining. These findings underscore the importance of implementing management and conservation measures to mitigate negative impacts on water resources in the region.
