Depicting the historical pollution in a Pb–Zn mining/smelting site in Kabwe (Zambia) using tree rings

Popis výsledku v původním jazyce

High concentrations of metals arepresent only in the top layers of soil and are higher in soils closer to the smelter (up to 16000 mg kg???? 1 Pb; 14000mg kg???? 1 Zn; 600 mg kg???? 1 Cu) compared to remote soils (up to 194 mg kg???? 1 Pb; 438 mg kg???? 1 Zn; 46 mg kg???? 1 Cu).Metals are also present in trees and the one located furthest from the slag dump contains higher metal concentrations(up to 6.48 mg kg???? 1 Pb; 10.6 mg kg???? 1 Zn; 10.2 mg kg???? 1 Cu), possibly due to the deposition of windblownparticles. Results of a sequential extraction procedure (SEP) showed that metal contaminants are notavailable for tree root uptake and the above-ground processes must be more important. The Pb isotopic ratios ofslags, tree rings, and topsoils average at 206Pb/207Pb = 1.15, corresponding to the signature of local ores andsmelting slags, thus confirming that the mine and smelter are the main sources of contamination in the area. Theresults were compared to the historical records of smelter production. Tree ring Pb and Zn concentrations, delta13Cand 206Pb/207Pb reveal linear dependence on production with different statistical significance.
