The concentrations of 21 elements were determined in 1 yr old needles of Norway spruce (Picea abies) at 39 different sites: The following soil parameters were measured at 3 different depths: pH, loss on ignition, total and EDTA-extractable concentrations of 28 elements. Needle concentrations were tested for correlations with soil parameters. The following significant correlations were found with pH: Al, Co, Cs, Mn, and Rb in needles increased with decreasing soil pH, whereas Ba and Sr decreased. Needle concentrations of As, Ca, Cu, Fe, K, La, Mg, P, Sb, Sc, V, and Zn had no significant correlations with soil pH. AI and Ba in needles correlated also with A1 and Ba extracted from the soil. Needle concentrations of the pairs Co and Mn, Cs and Rb, and Ba and Sr showed significant positive interelement correlations, whereas concentrations of P and K had negative interelement correlations with Mn. 相似文献
