“…Simultaneously, the accumulation of As and Sb in the sediments downstream of the confluence, that is, the intersection of the mining wastewater treatment plant outlet and TC karst river (TC 4 ), was also very high, reaching the peak of the TC karst river. This indicates that gold mining seriously impacts the accumulation of As, Sb, Zn and Cd in the sediments, especially As and Sb [37][38][39], similar to the study of other gold deposits [40][41][42][43]. In addition, the As and HMs background in the gold mining area may also be another reason [44].…”

Gold mining is associated with serious heavy metal pollution problems. However, the studies on such pollution caused by gold mining in specific geological environments and extraction processes remain insufficient. This study investigated the accumulation, fractions, sources and influencing factors of arsenic and heavy metals in the sediments from a gold mine area in Southwest China and also assessed their pollution and ecological risks. During gold mining, As, Sb, Zn, and Cd in the sediments were affected, and their accumulation and chemical activity were relatively high. Gold mining is the main source of As, Sb, Zn and Cd accumulation in sediments (over 40.6%). Some influential factors cannot be ignored, i.e., water transport, local lithology, proportion of mild acido-soluble fraction (F1) and pH value. In addition, arsenic and most tested heavy metals have different pollution and ecological risks, especially As and Sb. Compared with the other gold mining areas, the arsenic and the heavy metal sediments in the area of this study have higher pollution and ecological risks. The results of this study show that the local government must monitor potential environmental hazards from As and Sb pollution to prevent their adverse effects on human beings. This study also provides suggestions on water protection in the same type of gold-mining areas.

“…None of these mines have been rehabilitated. Some other examples, such as the Salsigne mine, show that rehabilitation remains partial and that deleterious environmental and health effects persist (Dondon et al, 2005;Delplace et al, 2022). Despite the passage of time and the implementation of environmental laws in all three countries and even lengthy legal proceedings, the fact that environmental and health consequences are now documented and sometimes acknowledged by local or national authorities did not change the attitude of governments.…”

Mediterranean mountains have been and continue to be used by human populations along an interweaving of numerous uses: agro-sylvo-pastoralism, trade, industry and mining have all gone hand in hand for several millennia. Mines are however a so important source of wealth that, by putting in contact external powers and mountain locals, it creates an imbalance of powers inducing structural violence and tensions. The 1830–1962 colonial era did change the magnitude of these imbalances and this affect all Mediterranean mountainous ranges. The French expansion did affect as a result the Moroccan Atlas, the Tunisia Coastal Mounts but also the French Pyrenees. The article explores the available archives regarding the history of three mines in each of these emblematic mountains with a shared mining and agro-sylvo-pastoral past and where mining were actually well-known: Sem-Rancié and Puymorens in the French Pyrenees, Mibladen and Zeïda in the Moroccan Middle Atlas and Jebel Ressass in Tunisia. These reconstructions show that the initial social and political situations, as diverse as they are, are of little importance in the trajectory of these mines: all of them see a rapid appropriation by economic powers that are more and more powerful and more and more distant as far as Paris, the common capital in colonial times, despite several revolts and tensions. The initial expansion then gave way to a structural crisis due to the competition with other mining sites until abandonment. The following powers, post-colonial in Morocco or Tunisia or decentralized in France, did not endorse any responsibility of this the post-mining environmental, social and economic legacy. For each of these sites, the mine could be seen as an indicator of the power balance evolution among activities and actors, a canary in the mine on which we propose a methodology for further investigations.

“…-The mining district of Salsigne, located in southern France, which as extensively exploited between the 4 th and the 1 st century BCE until the beginning of the 21 st century. Mines were first set up to produce Fe, Pb and Cu, then for the exploitation of gold during the 19 th century, and finally Salsigne became the biggest mine in the world for As production, until its closure in 2004 (Delplace et al, 2022). Recently, evidence of contamination of streams, sediments and soils in several metal(oid)s have been identified (Delplace et al, 2022;Khaska et al, 2018;Khaska et al, 2015).…”
