Impact of trace metals from past mining on the aquatic ecosystem: A multi-proxy approach in the Morvan (France)

People, pollution and pathogens – Global change impacts in mountain freshwater ecosystems

“…Mineral (=inorganic) micropollutants include trace elements that have no biological function or have a harmful effect when exceeding a certain concentration, termed Potentially Harmful Trace Elements (PHTEs, Camizuli et al, 2014aCamizuli et al, , 2014b. Organic micropollutants include organic molecules with adverse effects and long persistence in the envi ronment such as pesticides, hydrocarbons, etc.…”

Metals and arsenic in fish from a Ramsar site under past and present human pressures: Consumption risk factors to the local population

“…Mining contamination can occur mainly through acid drainage, atmospheric deposition, wind-blown particulate matter and mining waste disposal (e.g. Riba et al, 2005a;Taylor et al, 2014;Camizuli et al, 2014;Molina-Villalba et al, 2015). In some instances, such activities can affect more the surrounding areas than the local of the mining operations itself (Fernández-Caliani et al, 2008) since pollutants may be transported by water and air.…”

“…In some instances, such activities can affect more the surrounding areas than the local of the mining operations itself (Fernández-Caliani et al, 2008) since pollutants may be transported by water and air. In the environment, metals can accumulate in different environmental compartments (Riba et al, 2005b;Ruelas-Inzunza et al, 2011;Camizuli et al, 2014) including fish (e.g. Park and Curtis, 1997;Moiseenko and Kudryavtseva, 2001;Riba et al, 2005b;Jordanova et al, 2016).…”

Inorganic Chemistry in the Mountain Critical Zone

“…Few critical zone observatories (CZO) in Northern America and Europe are located in mountain environments (i.e., Southern Sierra CZO in Unites States and Strengbach-Vosges Mountains in France) and even fewer are actively monitoring and investigating ecogeochemical processes in mountain watersheds. This is despite the fact that many studies have demonstrated a mining PHTE legacy in remote areas and their resulting current impact on the environment (Bindler et al, 2012;Camizuli et al, 2014;Mariet et al, 2016;Monna et al, 2011). Additionally, mountain areas can be geologically enriched in PHTEs (i.e., As; González et al, 2006;Zaharescu et al, 2009), and these PHTEs can be remobilized and released in the watershed due to environmental modifications such as melting of glaciers or dehydration of wetlands.…”
