Chemical forms of Pb, Zn and Cu in the sediment profiles of the Pearl River Estuary.
TLDR
The chemical forms of heavy metals in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method and the 206Pb/207Pb ratios in the exchangeable fraction were the lowest among the five fractions, particularly in top sediments, showing the anthropogenic inputs ofheavy metals from recent rapid industrial development in the surrounding region.About:

Biogenic manganese oxides: Properties and mechanisms of formation
Bradley M. Tebo,John R. Bargar,Brian G. Clement,Gregory J. Dick,Karen J. Murray,Dorothy L. Parker,Rebecca Verity,Samuel M. Webb +7 more
TL;DR: The primary Mn(IV) biooxide formed is a phyllomanganate most similar to δ-MnO2 or acid birnessite, and metal sequestration by the Mn biooxides occurs predominantly at vacant layer octahedral sites.

Chemical sequential extraction for metal partitioning in environmental solid samples.
TL;DR: A comprehensive review of the sequential extraction schemes for metal fractionation in environmental samples (ie., sediment, soil, sewage sludge, fly ash, etc.), which covers principally the literature published over the last decade is presented.

Trace metal contamination in estuarine and coastal environments in China
Ke Pan,Wen-Xiong Wang +1 more
TL;DR: Elevated levels of metal contamination along China's coastal environment can increase the risk of metal exposure to humans by seafood consumption, raising the alarm for more stringent control of discharge of metals into environment.
Journal ArticleDOI
Heavy metals in agricultural soils of the Pearl River Delta, South China
TL;DR: The strong associations between anthropogenic Pb and the Fe-Mn oxide and organic/sulphide phases suggested that anthropogenic Cd and Pb was relatively stable after deposition in soils.
Journal ArticleDOI
Is there a future for sequential chemical extraction
TL;DR: This review uses evidence from the literature to consider the usefulness and limitations of sequential extraction, and discusses typical applications from the recent literature for which sequential extraction can provide useful and meaningful information.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.

Wim Salomons,Ulrich Förstner +1 more
TL;DR: In this paper, the authors studied the relationship between metal oxides and organic compounds and found that oxides are more likely to interact with organic compounds than with other organic compounds in the environment.
