Abstract. The chemical forms of heavy metals (Pb, Zn and Cu) in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method. The isotope ratios of 206Pb/207Pb in various chemical fractions were also measured to assess the potential Pb sources. Zinc and Cu were mainly associated with the residual fraction.

Abstract. Total concentrations of Cr, Cu, Zn, Pb and As were determined in soil samples from Beijing, Xinjiang, Heilongjiang, Yunnan, and Jiangsu provinces, using field portable X-ray fluorescence spectrometry (XRF). The relationship between XRF analysis results and the concentration of heavy metals in soils was established.

The predominant forms of heavy metals (Zn, Pb, Fe, Cu, Ni, etc.) in aerobic sediments are the carbonates and the oxide or hydroxide forms. An important consideration in modeling the sediment is the stable chemical form of the metal in question. Consider the reaction: Pb(OH)2(s) + CO2 (aq) PbCO3(s) + H2O AG° = 25 kJ/mol a.
