“…Whereby, these species can be considered as good candidates for phytostabiliaztion, mainly Sorghum halepense, due to the high tolerance demonstrated in this study, preventing a metal transfer to the food web. This is an important result; as it was pointed by Närhi et al (2012) recognition of plant species that tolerate high concentration of toxic elements is essential to phytostabilize them.…”

In the present work, we focused on soils contaminated with elevated lead concentrations in an agricultural and residential area surrounding a lead smelter plant in Bouwer, province of Córdoba, Argentina. The aim of this research work was to assess the phytoextraction suitability of native plant species growing in the vicinity of a former lead smelter.The lead concentration in leaves, stems and roots was determined in ten species collected at ten sampling sites along a lead concentration gradient in soil. It was found that at circa 1,600 μg g -1 Pb HCl 0,5 M extractable concentration in soil two native species, Tagetes minuta L.

Mining can have a notable environmental and social footprint both during the production phase and after the mine closure. We examined local stakeholders’ viewpoints on two post-mining areas in northern Finland, Hannukainen and Rautuvaara, using a public participation geographic information system (PPGIS) approach. Spatially explicit data on local residents’ and visitors’ values, knowledge needs, and future perspectives on mining landscapes were collected with an online map-based survey tool (Harava). The results show that post-mining sites were generally considered unpleasant places. A majority of respondents were of the opinion that areas would need better reclamation and landscaping measures. The landscape surrounding the post-mining sites contained a wide diversity of pleasant places with high nature and recreational value. Respondents addressed various environmental concerns related to the impacts of former mining activities on the quality of ground water and surface water, potential soil contamination, and the safety of natural products. Opinions on the planned mine reopening were strongly divided among the respondents. One of the key questions was whether a large open-pit mine and nature-based tourism can coexist in the same region. Our results highlight that “the shadow of the mine”—observed environmental impacts, uncertainties related to the spatial extent, duration, and magnitude of impacts, and knowledge gaps—can affect local stakeholders’ land use far outside the mining sites and long after the mine closure. Identifying and mapping stakeholder values, opinions, and knowledge needs could significantly improve post-mining land use planning and mitigate the loss of multifunctional landscapes.

“…The practice may lead to unfavourable conditions for plant growth, affecting the diversity and abundance of many species and hindering the reestablishment and development of natural vegetation and, therefore, regeneration of the whole ecosystem (Bradshaw, 1997;Adriano, 2001;Bell, 2001;Hernández and Pastor, 2008;Närhi et al, 2012). Depending on the geochemical composition of the mine waste, its disposal can have various different effects on soil quality: decreased nutrient contents (Schulz and Wiegleb, 2000;Nikolic et al, 2010); deteriorated physical quality (Shrestha and Lal, 2011); abrupt changes in pH (acidification or alkalinization) (Jurjovec et al, 2002;Aykol et al, 2003); and release of large amounts of toxic elements (Leblanc et al, 2000;Wu et al, 2011;Zornoza et al, 2012;Martínez-Sanchez et al, 2012;García-Lorenzo et al, 2012).…”
