摘要
The investigation is focused on the uptake of heavy metals and macronutrients fluxes in Pinus sylvestris L. wood and soil under the sampled trees from contaminated and control sites. Soil pH, total organic carbon (TOC) and total and bioavailable heavy metals lead (Pb), cadmium (Cd), copper (Cu) and zinc (Zn) and macronutrients, potassium (K) and magnesium (Mg) were compared on contaminated and control sites. Also, metal uptake of contaminated and control pine woods was determined. Concentrations of soil bioavailable Cd (0.009 mg kg(-1)), Pb (0.11 mg kg(-1)), Cu (0.076 mg kg(-1)), Zn (0.51 mg kg(-1)) and K (24.42 mg kg(-1)), Mg (8.44 mg kg(-1)) on the contaminated plot were significantly higher (p < 0.001) than on the control plot 0.00004 mg kg(-1) for Cd, 0.007 mg kg(-1) for Pb, 0.002 mg kg(-1) for Cu, 0.22 mg kg(-1) for Zn and 7.81 mg kg(-1) for K, 2.40 mg kg(-1) for Mg. In addition, the percentage of bioavailable metals in contaminated soils was higher. Pb (34.49 mg kg(-1)), Cu (0.258 mg kg(-1)), Zn (1.36 mg kg(-1)) and K, Mg concentrations in wood were statistically higher than on the control site Pb (0.01 mg kg(-1)), Cu (0.172 mg kg(-1)), Zn (0.93 mg kg(-1)), at p < 0.05 and p < 0.001, respectively. Cd did not show any significant difference in concentration on the contaminated plot in comparison to the control site.
