Mercury distribution in different environmental matrices in aquatic systems of abandoned gold mines, Western Colombia: Focus on human health

Impact of global warming on regional cycling of mercury and persistent organic pollutants on the Tibetan Plateau: current progress and future prospects

“…[157][158][159] Subsequently, MeHg poses serious threats due to higher bioaccumulation potential in sh and other aquatic organisms, posing a threat to carnivores and even humans. [160][161][162] A previous study disclosed that sh has a lower growth rate with a long life span, a low MeHg removal rate and a high level of sh MeHg accumulation in the food chains of the aquatic ecosystem on the TP, and enrichment of Hg in sh was found. 163 Therefore, with the continuous warming of the climate, continuous release of Hg from TP glaciers, permafrost and snow will also increase the accumulation of Hg in sh and other animals, following its transformation into MeHg.…”

Neuropsychological effects and cognitive deficits associated with exposure to mercury and arsenic in children and adolescents of the Mojana region, Colombia

“…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).…”

Non-destructive mercury exposure assessment in the Brandt’s hedgehog (Paraechinus hypomelas): spines as indicators of endogenous concentrations

“…gold), wastewater treatment, improper disposal of certain products, and the use of pesticides and fertilizers (Smart and Hill 1968;Mortvedt 1995;Navarro et al 1996;Wagner-Döbler 2003;Yasuda et al 2004;Zheng et al 2007;Zhong et al 2018;Tang et al 2018Tang et al , 2020Sun et al 2019b;Wang et al 2019). Due to its known toxicity, bioavailability and bioaccumulation potential, Hg environmental pollution has caused a growing worldwide concern (Gutiérrez-Mosquera et al 2021). When reaching aquatic ecosystems, inorganic Hg can be methylated to methylmercury (MeHg) by the action of microorganisms and bioaccumulate into the food chain, where it can cause severe damage to the biota and eventually to humans, including developmental and neurological health issues (Nogara et al 2019;Gutiérrez-Mosquera et al 2021).…”
