“…Our results clearly supported the combination of highest doses of limestone (10 t ha À1 ) and compost (225 t ha À1 ) materials in the reclamation of acidic Cu contaminated soils, consistent with several previous trial studies (Winterhalder, 1996;Madejon et al, 2006;Mench et al, 2006;Kumpiene et al, 2008;Córdova et al 2011;Ulriksen et al, 2012). Perspectives will be the implementation of the process to a larger area of the contaminated area.…”

“…This result can be explained by reduction of Cu bioavailability and better nutritional status in plots heavily amended with compost and limestone. Similar spontaneous plant colonisation patterns in bare trace metal-contaminated soil (As, Bi, Cd, Cu, Pb, Sb, Ti, and Zn) following lime and compost amendments have been reported (Madejon et al, 2006;Córdova et al 2011;Ulriksen et al, 2012), but apparently never in tropical Africa. In addition, Kucharski et al (2005) demonstrated enhancement in plant physical properties might also be involved following amendment, particularly improvements in water holding capacity and root growth.…”

“…There are few reported field studies that have evaluated the feasibility of assisted phytostabilization of mine tailings in semi-arid environments (Brown et al, 2009; Clemente et al, 2012; Cordova et al, 2011; Pardo et al, 2014; Santibañez et al, 2012). The goal of this study was to determine whether assisted phytostabilization could be successfully implemented at the Iron King Mine and Humboldt Smelter Superfund (IKMHSS) site which has mine tailings that are characterized by extreme acidity and high levels of arsenic, lead, and zinc (Root et al, 2015).…”

Standard practice in reclamation of mine tailings is the emplacement of a 15 to 90 cm soil/gravel/rock cap which is then hydro-seeded. In this study we investigate compost-assisted direct planting phytostabilization technology as an alternative to standard cap and plant practices. In phytostabilization the goal is to establish a vegetative cap using native plants that stabilize metals in the root zone with little to no shoot accumulation. The study site is a barren 62-hectare tailings pile characterized by extremely acidic pH as well as lead, arsenic, and zinc each exceeding 2000 g kg−1. The study objective is to evaluate whether successful greenhouse phytostabilization results are scalable to the field. In May 2010, a 0.27 hectare study area was established on the Iron King Mine and Humboldt Smelter Superfund (IKMHSS) site with six irrigated treatments; tailings amended with 10, 15, or 20% (w/w) compost seeded with a mix of native plants (buffalo grass,arizona fescue, quailbush, mesquite, and catclaw acacia) and controls including composted (15 and 20%) unseeded treatments and an uncomposted unseeded treatment. Canopy cover ranging from 21 to 61% developed after 41 months in the compost-amended planted treatments, a canopy cover similar to that found in the surrounding region. No plants grew on unamended tailings. Neutrophilic heterotrophic bacterial counts were 1.5 to 4 orders of magnitude higher after 41 months in planted versus unamended control plots. Shoot tissue accumulation of various metal(loids) was at or below Domestic Animal Toxicity Limits, with some plant specific exceptions in treatments receiving less compost. Parameters including % canopy cover, neutrophilic heterotrophic bacteria counts, and shoot uptake of metal(loids) are promising criteria to use in evaluating reclamation success. In summary, compost amendment and seeding, guided by preliminary greenhouse studies, allowed plant establishment and sustained growth over four years demonstrating feasibility for this phytostabilization technology.

“…Nevertheless, over the years, new companies have settled in the area, creating a scenario that severely affects human health [13] and causes environmental stress. The latter is evident in the level of contamination by heavy metals in the soil and water matrix, ultimately affecting the ecosystem of the area [14,15,16]. The second coastal wetland of this study is a lagoon called Matanzas, which forms part of the El Yali basin.…”

Being adapted to saline environments, halophytes are plant species that have received considerable attention due to their ability to cope with environmental stress factors, such as high concentrations of soluble salts and heavy metals. In this work, we focused on determining if the Sarcocornia neei (S. neei) plant can be considered as an indicator of heavy metal pollution in soil. This was done by analyzing the concentration of cadmium (Cd), lead (Pb), copper (Cu), and arsenic (As) in plants and soil sampled from two wetlands in the central zone of Chile: a wetland contaminated by industrial activities and a wetland protected by the Chilean government. In addition, 14 fertility parameters (pH, electrical conductivity, organic matter, nitrogen (N), phosphorus (P), potassium (K), sodium (Na), Pb, calcium (Ca), magnesium (Mg), Manganese (Mn), zinc (Zn), iron (Fe), and boron (B)) were analyzed for soil samples in both wetlands. This was done to differentiate between available elements and contamination by heavy metals. Plant and soil samples in the contaminated wetland exhibited significantly higher heavy metal concentrations in comparison to samples analyzed from the protected wetland. This indicates that the S. neei plant can be further researched as an indicator of heavy metal pollution in saline soils and possibly for phytoremediation purposes.
