“…Numerous studies have investigated the phytoavailability of As and Pb from various sources including the availability of As or Pb to crops grown on soils amended with sewage sludge (Lutrick et al, 1982;Narwal et al, 1983;Keefer et al, 1986), slag (Bunzl et al, 2001), phosphorus fertilizers (Goodroad and Caldwell, 1979), or fungicidal sprays (Merry et al, 1983;Merry et al, 1986); and As and Pb uptake by crops from the soils contaminated by mining and smelting activities (Xian, 1989;Davies, 1992;Levy et al, 1992;Taylor et al, 1992;Pichtel and Salt, 1998;Klassen et al, 2000;Roussel et al, 2000). The added As or Pb reacts with Fe and other soil constituents (Goldberg, 1986;Ainsworth et al, 1994;Manning and Goldberg, 1996;Sauvé et al, 2000;Saha et al, 2001).…”

Some waste-derived trace element fertilizers may contain elevated amounts of arsenic (As) and/or lead (Pb), and the impact of their use on As and Pb accumulation in soil and uptake by plants should be investigated. This greenhouse study examined how increasing rates of an iron (IR) fertilizer, containing 4806 mg kg −1 of As, and a zinc fertilizer (G-Zn), containing 18080 mg kg −1 of Pb, and liming affected As and Pb availability and uptake by lettuce (Lactuca sativa L.) in a silt loam soil. Additions of As as As 2 O 3 and Pb as PbCl 2 to the soil were included for comparison. Soil total and NaHCO 3 -extractable As increased with increasing inputs of As regardless of As source. This was true also for soil total and DTPA-extractable Pb. Sufficient oxidation of arsenopyrite (FeAsS) in the IR could have occurred, resulting in 36.4% of total As in IR being extractable by NaHCO 3 . Only extremely small fractions of the added As from IR (5 × 10 −3 %) and of the added Pb from G-Zn (7 × 10 −3 %) were accumulated in the plant. Source had an effect on As, but not Pb, accumulation by lettuce. The lower accumulation of As by the plant from IR than from As 2 O 3 could be attributed to a high molar ratio of Fe to As (419) in the readily labile As fraction to render As in IR less available than As in As 2 O 3 . The molar ratio of Fe to Pb in the readily labile fraction of Pb in G-Zn was zero, which limited the influence of Fe on the accumulation of Pb from G-Zn despite its extremely high total Fe (18.3%) content. The transfer coefficients of the added As (0.013) and Pb (0.014) over all sources and lime rates were very low. Since nearly all of As and Pb added from the fertilizers remained in the soil, effects of long-term use of the products on As and Pb accumulation in the soil and uptake by the plant remain to be studied.

“…Some studies have focused on the effects of surface mining and the mobilization of heavy metals (Bhuiyan et al 2010;Rashed 2010;Ciszewski et al 2012), and have often revealed a high degree of metal toxicity in mine spoils and soils affected by the oxidation of pyritic material (Pérez and de Anta 1992;Taylor et al 1992Taylor et al , 1993Monterroso et al 1999;Clark et al 2001;Iavazzo et al 2012). However, information on the occurrence of AMLs all over the world together with the pollution database is not available in the form of a comprehensive review.…”

The lack of awareness for timely management of the environment surrounding a metal mine site results in several adverse consequences such as rampant business losses, abandoning the bread-earning mining industry, domestic instability and rise in ghost towns, increased environmental pollution, and indirect long-term impacts on the ecosystem. Although several abandoned mine lands (AMLs) exist globally, information on these derelict mines has not been consolidated in the literature. We present here the state-of-the-art on AMLs in major mining countries with emphasis on their impact towards soil health and biodiversity, remediation methods, and laws governing management of mined sites. While reclamation of metalliferous mines by phytoremediation is still a suitable option, there exist several limitations for its implementation. However, many issues of phytoremediation at the derelict mines can be resolved following phytostabilization, a technology that is effective also at the modern operational mine sites. The use of transgenic plant species in phytoremediation of metals in contaminated sites is also gaining momentum. In any case, monitoring and efficacy testing for bioremediation of mined sites is essential. The approaches for reclamation of metalliferous mines such as environmental awareness, effective planning and assessment of pre-and postmining activities, implementation of regulations, and a safe and good use of phytostabilizers among the native plants for revegetation and ecological restoration are discussed in detail in the present review. We also suggest the use of microbially-enhanced phytoremediation and nanotechnology for efficient reclamation of AMLs, and identify future work warranted in this area of research. Further, we believe that the integration of science of remediation with mining policies and regulations is a reliable option which when executed can virtually balance economic development and environmental destruction for safer future.

“…Métodos, como extrações químicas, simples ou seqüenciais, permitem inferir sobre a disponibilidade dos metais em substratos e conhecer a dinâmica de equilíbrio químico entre as formas dos metais (Amaral Sobrinho et al, 1997). Assim, soluções vêm sendo testadas para extrair os metais pesados do solo, incluindo água, agentes extratores ácidos, quelantes e redutores (Taylor et al, 1992;Pierzynski & Schwab, 1993;Abreu et al, 1995).…”

RESUMODepósitos de rejeitos e pilhas de estéril, decorrentes de atividades de mineração, podem ser fontes de contaminação ambiental, por causa da presença de metais pesados e arsênio, principalmente quando esses materiais contêm minerais sulfetados e teores elevados de metais. O objetivo deste trabalho foi caracterizar o rejeito proveniente do beneficiamento de minério de ouro de uma mineração no estado de Minas Gerais, para avaliação de problemas de drenagem ácida e solubilização de metais e para planejamento da revegetação do local. Amostras de rejeito foram coletadas na camada superficial (0-20 cm), sendo submetidas a análises químicas de rotina da fertilidade do solo e a uma caracterização química específica de Ni, Cu, Pb, Cd, Fe, Zn, Cr, As e S extraídos em Água Régia, Mehlich-1, EDTA e água deionizada. Foram determinados o potencial de acidez (PA), o potencial de neutralização (PN) e equilíbrio ácido-base (EAB); além da realização de análise granulométrica e difração de raios-X. As amostras analisadas apresentaram baixos teores de matéria orgânica, P e K, alta acidez e salinidade, além de alto teor de As, o que indica sérias restrições ao estabelecimento de espécies vegetais. O rejeito apresentou potencial de geração de acidez e solubilização de elementos como As, Fe e S, o que pode acarretar problemas ambientais, como a drenagem ácida e a contaminação de solos e cursos d'água, bem como a incorporação desses elementos na cadeia trófica.Termos de indexação: drenagem ácida, extratores químicos, poluição ambiental.
