Résumé
This study aimed to assess the water quality of the Perequê River, Porto Belo, Santa Catarina, Brazil, through a biomarker approach in the native fish species Geophagus brasiliensis, and the sediment chemical quantification of the herbicides glyphosate and bentazone used in irrigated rice plantations. This river is used for the public water supply of two municipalities. The first sampling (S1) was in November 2016, in the spring season and the second (S2), in March 2017, in the fall season. In each sampling, two points of the river were analyzed, one upstream of the accumulation dam and the water catchment point for water supply of the Porto Belo WTS (P1), and another downstream (P2) with water, sediment, and fish sampling. Biotransformation, oxidative stress, histopathological and genotoxic biomarkers were analyzed in different tissues. The presence of glyphosate was detected in the sediment (11.7 μg·kg
