“…1), probably due to its slightly acidic pH. However, the available concentrations of Zn were high in all soils due to the great mobility of this metal even at neutral pH (González et al, 2011). Again, the watercourse soil showed the highest concentrations of available Zn (Fig.…”

“…A long persistence of easily leaching sulphur compounds in soils, namely 16 years after mining in the Machów mine was neglected and 7 years after the Jeziórko mine was closed down, accounts for the formation of sulphate minerals. González et al (2011) found that in the periods of high evaporation, when exposed to low pH values and a relatively high concentration of soluble salts present in mining waste, mostly ions (SO 4 2-, Al 3 and Mg 2 ), as well as trace elements (Zn 2 , Cd 2 , Pb 2 ), more or less complex sulphate minerals get formed. During precipitation, secondary salt deposits dissolve, thus contributing to a very low pH value and a release of ions Mg, Al and Zn, and mostly SO 4 2-.…”

“…De modo semelhante a estes resultados, González et al (2011) também verificaram o aumento do níveis de fitotoxicidade ao executar bioensaios Com L. sativa L. em uma área impactada por drenagem ácida de minas, reforçando o papel central da acidez na toxicidade observada. Por outro lado, é importante novamente destacar a influência do pH Tabela 2 -Bioensaio agudo com Eisenia andrei em misturas de solo artificial:resíduo de mineração de carvão: níveis de mortalidade dos organismos-teste e determinação das concentrações de metais (em mg kg -1 ) em tecidos de oligoquetas (sobreviventes e antes da exposição).…”
