“…Although REE are generally thought to be benign (Hirano and Suzuki, 1996;Tyler, 2004), relatively few toxicity studies have yet been undertaken because REE are often in such low concentrations as to be difficult to detect (Tyler, 2004). REE concentrations are highly elevated in some AMD (Verplanck et al, 2004;Cravotta, 2008b;Gilchrist et al, 2009) and could eventually prove to be of importance. Hirano and Suzuki (1996) document that extremely elevated concentrations (ppm) of REE can be toxic to mammals.…”

“…Water samples were collected from a stream flowing through Sterling Mine (41°11.868N, 74°15.663W) and two other locations-still water around the main entrance of Sterling Mine (41°11.805N, 74°15.71W) and from a spring receiving water that is drained through tailings pile (41°11.803N, 74°15.616W). Field measurements, sample preparation, chemical and quality control analyses for the water samples were performed using the methods described in Gilchrist et al (2009). Sample collection and preparation for analysis were conducted according to the US Geological Survey (USGS) National Field Manual for the Collection of Water Quality Data (USGS 2005).…”

“…Besides iron mining, sulfide mining was also conducted. Gilchrist et al (2009) showed that these mines could pose an environmental threat from acid mine drainage (AMD) with elevated metals. Volumetrically, spoils from sulfide mines are insignificant compared to those from large-scale iron-mining operations like those in the Sterling magnetite mine area (Fig.…”

Organic material in metal contaminated soils around an abandoned magnetite mine-smelter complex in the critical Highlands watershed protects the groundwater and surface water from contamination. Metals in these waters were consistently below local and national water standards. Two groups of soil types cover the area: (1) Group A disturbed metal-rich soils, and (2) Group B undisturbed organic soils. Chromium and nickel were more elevated than other metals with Cr more widespread than Ni. In Group A, Cr correlated strongly with sesquioxides in the lower horizons (Fe 2 O 3 : r = 0.74, p \ 0.025; Al 2 O 3 : r = 0.92, p \ 0.005). In Group B, Cr correlated strongly (r = 0.96, p \ 0.005) with soil organic matter (SOM) in the O-horizons. Ni-Cr (Group A: 52 and 70% in O-and lower horizons, respectively; Group B: *100% in both horizons) and V-Cr correlations (78% only in Group A lower horizons) suggest similar retention mechanisms for these elements. Average soil pH CaCl 2 for both groups ranged between 3.65 and 5.91, suggesting that soil acidity is determined by organic acids and solubility of Al 3? releasing H ? ions. SOM and sesquioxides contribute significantly to creating naturally occurring filtration systems, removing metals, and protecting water quality. High Ca, Fe, and Ti in Group A soils suggest slag and ash were mixed into the soils. Some low-Cr sources include magnetite, slag, and ash (100, 100 and 200 mg/kg, respectively). Constant ZrO 2 :TiO 2 ratios in the lower soils indicate soil formation from breakdown of underlying tailing rocks, contributing Cr to these layers.

“…The deterioration of water quality caused by mine drainages and/or the weathering of residues from ore exploitation and processing has been recognised worldwide (e.g. Gilchrist et al 2009;Gómez-Alvarez et al 2009;Harrison et al 2003;Loredo et al 2008;Monjezi et al 2009;Neal et al 2005;Peplow and Edmonds 2006;Wolkersdorfer and Bowell 2005). Therefore, the chemical contamination of water systems at abandoned mining sites demands investigation strategies capable of describing sources and pathways of contaminants and containment strategies devoted to limit the migration of toxic components off-site.…”

Public awareness of environmental health\ud issues has increased significantly in recent years, creating the need for detailed scientific studies that can identify potential environmental problems. This paper reports the results of hydrogeochemical surveys carried out in Sardinia,\ud an Italian region with a long mining history. When mining\ud operations in Sardinia ceased, actions for limiting the potential adverse effects of mine closure on the water\ud system were not undertaken. Drainages from flooded mines\ud and seeps from mining residues left on the ground are the main mining-related sources of contamination in Sardinia.\ud Due to the proximity of mining sites to water resources and land that is within reach of animals and humans, the major risks to human health are associated with the direct discharge\ud of contaminated waters into the streams and soils\ud located down-gradient of the abandoned mines. Results of\ud hydrogeochemical surveys carried out under different\ud seasonal conditions showed that the dispersion of toxic and harmful elements (As, Cd, Ni, Pb, Sb and Zn) increases\ud during the rainy season, especially under high runoff conditions.\ud These results should help regional and national\ud authorities to address present environmental regulations, particularly those regarding the quality of water resources.\ud Furthermore, the results might be useful elsewhere for\ud planning remediation actions at abandoned mining sites.\ud Lessons learned by past mining in Sardinia indicate that correct disposal and management of mining residues\ud should be mandatory from the beginning of exploitation\ud and processing at each active mine. This would allow\ud reduction of the environmental risks as well as the cost of remediation
