摘要: The concentrations of metals (Pb, Cu, Zn, Co, Ni, Fe and Mn) in the <2.5 μm fraction surface soils (0–5 cm) from highly industrialized areas Xuzhou (China) were determined. All analyzed with exception Mn Co present study showed elevated compared to background concentrations, particularly for Zn. Metal enrichment was positively correlated carbonate complexation constants (but not bulk solubility products) as well first stability metal-citrate, likely suggesting that both metal–organic and/or precipitation surfaces subsequently adsorb are responsible these metal on samples. Sequential extraction analysis shows Pb, largely associated reducible fraction, whereas Ni oxidisable fraction. Manganese is only showing significant association exchangeable (up 33 %), it may be most susceptible mobilization. Mineral magnetic indicates ferrimagnetic SSD + SP (stable single domain superparamagnetic) minerals dominated soils. Lead, Cu Zn found show correlations χlf (p < 0.01), technique might beneficially used a rapid inexpensive method estimate contaminations
