孟加拉国浅层全新世含水层中砷的可逆吸附与淋洗
Kathleen A Radloff,Yan Zheng,Martin Stute et al.
Kathleen A Radloff et al.
The spatial heterogeneity of dissolved arsenic (As) concentrations in shallow groundwater of the Bengal Basin has been attributed to transport of As (and reactive carbon) from external sources or to the release of As from within grey sand f...
Evidence of Decoupling between Arsenic and Phosphate in Shallow Groundwater of Bangladesh and Potential Implications [0.03%]
孟加拉国浅层地下水砷和磷酸盐的解耦合现象及其潜在意义
Z Aziz,B C Bostick,Y Zheng et al.
Z Aziz et al.
Reductive dissolution of iron oxyhydroxides and reduction of arsenic are often invoked as leading causes of high dissolved As levels in shallow groundwater of Bangladesh. The second of these assumptions is questioned here by comparing the b...
