“…The Mojana region. translated into contamination of different animal species and water bodies (Pedraza and Espinosa-Ramírez, 2022;Gutiérrez-Mosquera et al, 2021;Alonso et al, 2014Alonso et al, , 2020, and specifically in the Mojana region, which put biodiversity and human health at risk (Enamorado-Montes et al, 2021;Galeano-Paez, 2021;Buelvas-Soto et al, 2022). Similarly, regarding human exposure, several associated evidences have been reported in Colombia in which these contaminant levels were above the reference value considered safe presenting indicators from 1.87 μg/g to 22.98 μg/g for Hg in hair (Manjarres-Suárez & Olivero-Verbel, 2020;Salazar-Camacho et al, 2017;Valdelamar-Villegas and Olivero-Verbel, 2019) and between 5.5 μg/L 14.63 μg/L for Hg in blood (Díaz et al, 2018;Gutiérrez-Mosquera et al, 2018), as of high concentrations for As in blood, especially for inhabitants near areas of mining activity (Cruz-Esquivel et al, 2019).…”
