Total and extractable metal concentrations in the three groups of soils sampled at the Santo Amaro (BA, Brazil) study area and respective reference soils.

aNumbers in superscript indicate the exceedance (multiplication factor) relatively to the HC50cor (corrected Dutch HC50EC50 values after Rutgers et al. 2008) (Ex: the [Pb] at P150T1: 37460 (10.4), indicates that [Pb] was 10.4 times higher than the HC50cor for Pb).bTotal metal concentrations in several sampling points exceeded the Eco-SSL for plants proposed by USEPA (2004): Pb: 120 mg/kg soil; Mn: 220 mg/kg soil; Cd: 32 mg/kg soil; Cu: 70 mg/kg soil; Ni: 38 mg/kg soil; Zn: 160 mg/kg soil.Total and extractable metal concentrations in the three groups of soils sampled at the Santo Amaro (BA, Brazil) study area and respective reference soils.
