The soil Cu and
Pb concentrations were measured after sieving (2 mm) and oven
drying (75 °C) the soil samples. To measure total metal concentrations,
0.1 g oven-dried soil samples were digested with 2 ml of a mixture
(4:1 = v:v) of HNO3 (65%, p.a., Riedel-deHaën, Seelze, Germany)
and HCl (37%, p.a., Baker Philipsburg, NJ, USA) at 140 °C for 7 h in a
macro-destruction oven.
