The aim of this study is to investigate the environmental risk of long-term metallurgical
waste disposal. The investigated site was used for the open storage of lead and zinc waste materials
originating from a lead smelter and refinery. Even after remediation was performed, the soil in
the close vicinity of the metallurgical waste deposit was heavily loaded with heavy metals and
arsenic. The pollutants were bound in various compounds in the form of sulfides, oxides, and
chlorides, as well as complex minerals, impacting the pH values of the investigated soil, such that
they varied between 2.8 for sample 6 and 7.34 for sample 8. In order to assess the environmental
risk, some eight soil samples were analyzed by determining the total metal concentration by acid
digestion and chemical fractionation of heavy metals using the BCR sequential extraction method.
Inductively coupled plasma optical emission spectrometry (ICP-OES) was used to determine six
elements (As, Cd, Cu, Pb, Zn, and Ni). Total concentrations of the elements in the tested soil samples
were in the range of 3870.4–52,306.18 mg/kg for As, 2.19–49.84 mg/kg for Cd, 268.03–986.66 mg/kg
for Cu, 7.34–114.67 mg/kg for Ni, 1223.13–30,339.74 mg/kg for Pb, and 58.21–8212.99 mg/kg for
Zn. The ratio between the mean concentrations of the tested metals was determined in this order:
As > Pb > Zn > Cu > Ni > Cd. The BCR results showed that Pb (50.7%), Zn (49.2%), and Cd
(34.7%) had the highest concentrations in mobile fractions in the soil compared to the other metals.
The contamination factor was very high for Pb (0.09–33.54), As (0.004–195.8), and Zn (0.14–16.06).
According to the calculated index of potential environmental risk, it was confirmed that the mobility
of Pb and As have a great impact on the environment.
