“…As a result, such sites often do not support adequate vegetation cover. This leaves the soil surface exposed to the erosion leading to the transport, dispersion, and deposition of tailings particles and associated hazardous contaminants into neighboring soils and water sources, − including areas that may be important for agriculture. − This is intensified in arid and semiarid environments because of extreme high temperatures and low precipitation. , Recent studies suggest that wind dispersion is one of the most important routes of exposure for communities close to mine tailings ,,,− …”

Environmental and health risk concerns relating to airborne particles from mining operations have focused primarily on smelting activities. However, there are only three active copper smelters and less than a dozen smelters for other metals compared to an estimated 500000 abandoned and unreclaimed hard rock mine tailings in the US that have the potential to generate dust. The problem can also extend to modern tailings impoundments, which may take decades to build and remain barren for the duration before subsequent reclamation. We examined the impact of vegetation cover and irrigation on dust emissions and metal(loid) transport from mine tailings during a phytoremediation field trial at the Iron King Mine and Humboldt Smelter Superfund (IKMHSS) site. Measurements of horizontal dust flux following phytoremediation reveals that vegetated plots with 16% and 32% canopy cover enabled an average dust deposition of 371.7 and 606.1 g m y, respectively, in comparison to the control treatment which emitted dust at an average rate of 2323 g m y. Horizontal dust flux and dust emissions from the vegetated field plots are comparable to emission rates in undisturbed grasslands. Further, phytoremediation was effective at reducing the concentration of fine particulates, including PM, PM, and PM, which represent the airborne particulates with the greatest health risks and the greatest potential for long-distance transport. This study demonstrates that phytoremediation can substantially decrease dust emissions as well as the transport of windblown contaminants from mine tailings.

“…5 Understanding the retention and mobility of metals in organic-rich soils requires consideration of the three major soil components: mineral particles, OM, and microorganisms. 6,7 Although the role of each component in the mobility of metals in contaminated sites is well documented, the propagation of their effects on metal mobility and retention is less explored. 2 For example, OM is oen stabilized by Fe-oxides, silica and clay minerals, leading to a ternary system composed of OM, minerals and metals.…”

“…In addition, manganese, iron, and arsenic were found to be enriched in spilled material beyond sediment quality guidelines for the protection of aquatic life (CCME, 2018; MPMC, 2015a). The environmental risk from trace metals in tailings is dependent on biogeochemistry and "scale specific processes of metals mobility" (Jianu et al, 2012). The spilled tailings material in Quesnel Lake is known to be small (mean particle size ~50 μm) (MPMC, 2016).…”

Spatial and trophic biomonitoring of trace metals in aquatic environments following the Mt. Polley Mine tailings spill

A large (~25 M m 3) copper-gold tailings spill occurred in 2014 at the Mt. Polley Mine, which released solid and liquid waste and caused a debris flow into nearby Polley Lake and Quesnel Lake. This study examined the spatial and trophic patterns of trace elements in water bodies impacted by the spill between April and November 2016. Concentrations of trace metals in biofilm, invertebrates, sediments, and water were measured and analyzed using DGT and ICP-MS. Trophic positioning of sampled organisms was established using invertebrate functional feeding groups, and stable isotope ratios. Spatial results indicated that copper and vanadium concentrations in biofilm and invertebrates at impacted environments regress significantly with distance to the spill. Trophic results show evidence of copper bioaccumulation and selenium trophic magnification in biofilm and invertebrates from impacted waters. These effects appear to have seasonal variations, with stronger trophic and spatial relationships during spring overturn of Quesnel Lake.
