The As hosted in the primary minerals is expected to be concentrated in the titano-magnetite. This mineral is stable in contact with both surface- and ground waters and does not, therefore, supply As to the water, explaining the difference in mobility between As and B. Aqueous As ...

The groundwater is generally CaHCOtype. The concentration of major constituents in groundwater is relatively high in shallow aquifer and gradually decreases with increasing depth in most cases. This suggests that surface processes (local... D Halder,H Nidhardt,S Bhowmick,... 被引量: 0发表: 201...

These sites were mainly affected by point source pollution of arsenic, which were derived from sewage and industrial waste water. While the influence of run off was not significant. The content of arsenic ranged from 2.72 to 71.5 mg·kg-1 in the surface sediment of the PRD, with the ...
Over the past few years, numerous surveys referred to the occurrence in water bodies of organic and inorganic micropollutants, such as endocrine-disrupting compounds, pharmaceuticals, and personal care products in surface waters, drinking water, and wastewater effluents. The occurrence of such compounds...

Because the lake is a result of damming, it is perched above the water table and therefore As transport may occur via downward movement of porewaters and/or groundwaters. Preliminary evidence for this was found in the form of iron flocculates enriched in As which were found in surface ...
