Resumo: Rivers protection is fundamental for the socioecological systems, and the benthic macroinvertebrates communities can be used to assess the quality of river waters. This study aimed to assess the water quality at Cachoeira do Paraíso waterfall, Peruíbe, SP, based on the benthic macrofauna. Sampling took place at 3 sampling sites, under different levels of anthropic influence. Water physical-chemical and sedimentological parameters were evaluated, as well as macrobenthic organisms. Samplings were done by kick sampling technique. The organisms were identified at the lowest possible taxonomic level and points were attributed to each group according to their respective sensitivity and tolerance to pollutants. Then, a biological index was calculated to indicate the water quality. Ecological indices were calculated and compared using ANOVA. The water physical-chemical parameters showed to be within the legal standards. 13 taxonomic groups of benthic macroinvertebrates were identified, with the Shannon diversity indices indicating similar taxonomic diversity. The score given to each taxa generated biological indices for each sample, ranging from regular to excellent. Diptera (with head) I was the most representative taxon, and sensitive taxonomic groups, were found in all the sampling sites, suggesting a good quality of the water body during the period of study.

Este estudio evaluó la calidad del agua en Cachoeira do Paraíso, Peruíbe, SP, con base en el análisis de la macrofauna bentónica. El muestreo se realizó en 3 puntos de recolección, bajo diferentes grados de influencia humana. Se midieron parámetros fisicoquímicos del agua, análisis sedimentológicos de la comunidad macrobentónica. Las recolecciones se realizaron mediante la técnica de “kick sampling”. Los organismos se identificaron en el nivel taxonómico más bajo y se asignaron puntos según su sensibilidad y tolerancia a los contaminantes. Luego, se calculó un índice biológico para indicar la calidad del agua. Los índices ecológicos se calcularon y compararon mediante ANOVA. Los parámetros estaban dentro de los límites legales aceptables. Se identificaron trece grupos de macroinvertebrados bentónicos, con índices de diversidad de Shannon que indican una diversidad taxonómica similar. La puntuación otorgada a cada taxón generó índices biológicos, que van de regular a excelente. El grupo Dípteros (con cabeza) I fue el más representativo, encontrándose grupos taxonómicos sensibles en los diferentes puntos de muestreo, lo que sugiere una buena calidad del cuerpo de agua en el período.A proteção dos rios é vital para os sistemas sócio-ecológicos e as comunidades de macroinvertebrados bentônicos podem ser utilizados para avaliar a qualidade de suas águas. Este estudo avaliou a qualidade da água na Cachoeira do Paraíso, Peruíbe, SP, a partir da análise da macrofauna bentônica. A amostragem ocorreu em 3 pontos de coleta, sob diferentes graus de influência humana. Foram medidos parâmetros físico-químicos da água, análises sedimentológicas da comunidade macrobentônica. As coletas foram realizadas pela técnica “kick sampling”. Os organismos foram identificados ao menor nível taxonômico e foram atribuídos pontos de acordo com sua sensibilidade e tolerância aos poluentes. Então, foi calculado um índice biológico para indicação da qualidade de água. Índices ecológicos foram calculados e comparados por meio de ANOVA. Os parâmetros estiveram dentro dos limites legais aceitáveis. Foram identificados 13 grupos de macroinvertebrados bentônicos, com os índices de diversidade de Shannon indicando diversidade taxonômica similar. A pontuação dada a cada táxon gerou índices biológicos, variando de regular à excelente. O grupo Diptera (com cabeça) I foi o mais representativo, e grupos taxonômicos sensíveis, foram encontrados nos diferentes pontos amostrais, sugerindo uma boa qualidade do corpo hídrico no período.SciELO PreprintsSciELO PreprintsSciELO Preprints2021-08-05info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/273110.1590/SciELOPreprints.2731enghttps://preprints.scielo.org/index.php/scielo/article/view/2731/4791Copyright (c) 2021 Luiza Costa Mello, Denis Moledo de Souza Abessahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMello, Luiza CostaAbessa, Denis Moledo de Souzareponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-08-02T17:48:17Zoai:ops.preprints.scielo.org:preprint/2731Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-08-02T17:48:17SciELO Preprints - SciELOfalse
