Abstract: Bisphenol A (BPA) is an emerging contaminant, regularly detected in aquatic ecosystems, considered as an endocrine disrupting compound (EDC). Caffeine is another chemical related to human activity, often found in surface waters. The objective of this study was to evaluate the ecotoxicological risk due to BPA and caffeine in water samples from the Sinos River basin, Rio Grande do Sul, Brazil. Water samples were collected at three sites monthly from May 9 th, 2016 to April 11th, 2017 (n = 36). BPA concentrations… Show more

“…Because of its extensive use, it is a highly produced organic chemical with over five million tons produced each year (Fitzgerald et al 2015). Measured concentration of BPA in surface water ranges from nd-517 ng/mL (Peteffi et al 2019). Very high levels of BPA (17.2 mg/L) were detected from waste landfill leachates of Japan (Yamamoto et al 2001).…”

“…Biocides were selected based on their global high-volume usage and whether they have MCLs in Honduras, are classified as toxicological class 1A or 1B, or are prohibited biocides in Honduras. We also included other water-relevant compounds as positive controls (e.g., caffeine, abscisic acid) as they have been ubiquitously found in surface water around the world (Moschet et al 2013;Wu et al 2014;Carpenter & Helbling 2018;Carpenter et al 2019b;Peteffi et al 2019). Stock solutions of all biocide reference standards (Sigma-Aldrich) were prepared at 1 g L À1 in LC-MS-grade methanol (OmniSolv, VWR), nanopure water (EMD Millipore), LC-MS-grade acetonitrile (Fisher Chemical), ethanol (Decon Labs), or dimethyl sulfoxide (Macron Fine Chemicals) and stored at À20 °C.…”

“…Even though regardless of all the technology used, it is still not possible to identify all the pollutants, and mainly its interactions, which are necessary items for the evaluation of the ecological water condition. For this reason, the use of biomarkers models in ecotoxicology has attracting attention in the scientific field (CONAMA, 2005;Clavijo et al, 2016;Peteffi et al, 2019;Roubicek, Rech & Umbuzeiro, 2020;Brucker et al, 2021,).…”
