摘要: Total concentrations and extractable fractionations of As Sb were determined in soil samples from former mining sites Scotland Italy. Pseudo-total levels the sample between 50–17,428 mg/kg 10–1,187 (Scotland), 16–691 1.63–11.44 (Italy). Between 0.001–0.63% <0.001−8.82% total Sb, using, a single extraction bioavailability estimate. Data an As-specific procedure revealed that up to 60% was associated amorphous Fe-Al oxyhydroxide phase all soils. A non-specific-sequential test also showed be strongly with Fe (and Al) oxyhydroxides at both locations. In case addition crystalline Fe-oxide bound Al-silicate appeared significant. At appears chemically more accessible than consistent availability despite varied origin host properties.
