Copper accumulation and changes in soil physical–chemical properties promoted by native plants in ​​an abandoned mine site in northeastern Brazil: Implications for restoration of mine sites

Physico-chemical characteristics and heavy metal concentrations of copper mine wastes in Zambia: implications for pollution risk and restoration

“…3). And in comparison to other areas, the concentration of Cu in the mine wastelands is slightly higher than values reported from the Monarch south tailings in Botswana with copper concentration ranging from 865 to 2125 mg kg -1 (Vogel and Kasper 2002), soils around an abandoned mine site in south west Spain with 2874 mg kg -1 Cu (Fernández-Cadena et al 2014), in an abandoned Cu mine site in northeastern Brazil with concentration ranging from 3601 to 9601 mg kg -1 in the bulk soils (Perlatti et al 2015). The high Cu concentration in the present study may be attributed to the mineralogy of the studied sites and the processing efficiency.…”

Differential behavior of the summer cover crops in the absorption and translocation of copper

“…similar to those observed in several contaminated areas of Brazil (BRUNETTO et al, 2013;ANDREAZZA et al, 2013). According to PERLATTI et al, (2015) the soil available metal content are determined by extractors solutions that showed a high correlation with the heavy metal concentrations in the plant tissues. Under the experimental conditions of this study, the Mehlich-1 extractor revealed a higher correlation with the Cu levels in the plants.…”

“…In Brazil, the principal areas susceptible to copper contamination are the wastes disposed from mining, swine breeding and vineyards. Although, the areas affected by mining are comparatively small, they showed high contamination levels (PERLATTI et al, 2015). On the contrary, large areas exhibiting less copper contamination levels are observed where large quantities of liquid swine manure are frequently disposed, as food rations are high in copper (MALLMANN et al, 2014).…”

Soil Bioremediation in Heavy Metal Contaminated Mining Areas: A Microbiological/Biotechnological Point of View

“…In Southeastern Brazil, Perlatti et al [26] evaluated the possible implications for the use of plant species in restoring a copper mining area by calculating the balance between the copper mobilized in the rhizosphere and the copper absorbed by the plants. The results showed that none of the four evaluated plant species fulfilled the requirements for a classification as hyperaccumulator species (i.e.…”
