“…Sediment metal concentration was assessed using the probable effect concentration (PEC: MacDonald et al 2000 ) and the sediment pollution score (SedPoll: Costas et al 2018 ) calculated from As, Cd, Cu, Hg, Pb and Se sediment concentrations in the Nalón River basin. In our previous contributions we described the baseline concentrations (Ecological Tissue threshold concentration, ETTC of 9 metals in several biomonitors of the Nalón River basin, Rodriguez et al 2018 ), and more recently a bioaccumulation risk assessment was done, using the number of times the baseline concentrations in selected biomonitor taxa were exceeded (Rodriguez et al 2021 ). In the present contribution, ERs were estimated on the same dataset for each taxon and metal from nonlinear regression models of the tissue residues (abscissa) vs EQRs (ordinate).…”

“…In fact, arsenic appears in high concentrations in groundwater from geological sources, causing chronic health disorders [ 5 ]. Arsenic pollution in sediments and bioaccumulation has been demonstrated as one of the main causes of toxicity [ 3 ], and of the alteration of the ecological status in rivers affected by mining activities [ 6 , 7 ]. Integrating chemical analysis with biological endpoints can help in the monitoring and protection of aquatic ecosystems.…”
