A review of the source, behaviour and distribution of arsenic in natural waters
The range of As concentrations found in natural waters is large, ranging from less than 0.5 μg l−1 to more than 5000 μg l−1. Typical concentrations in freshwater are less than 10 μg l−1 andExpand
Hydrogeochemistry of arsenic and other inorganic constituents in groundwaters from La Pampa, Argentina
Groundwaters from Quaternary loess aquifers in northern La Pampa Province of central Argentina have significant quality problems due to high concentrations of potentially harmful elements such as As,Expand
Fluoride in Natural Waters
The element fluorine has long been recognised to have benefits for dental health: low-fluoride intake has been linked to development of dental caries and the use of fluoride toothpastes andExpand
Arsenic contamination of groundwater in Bangladesh
A survey of well waters (n=3534) from throughout Bang- ' ladesh, excluding the Chitt;agong Hill Tracts, has shown that water from 27% of the 'shallow' tubewells, that is wells less than 150 mExpand
Arsenic associations in sediments from the loess aquifer of La Pampa, Argentina
Groundwater from the Quaternary loess aquifer of La Pampa, central Argentina, has significant problems with high concentrations of As (up to 5300 μg L−1) as well as other potentially toxic traceExpand
Arsenic and selenium
This chapter outlines the main effects of arsenic and selenium on human and animal health, their abundance and distribution in the environment, sampling and analysis, and the main factors controllingExpand
Groundwater geochemistry and health: an overview
Abstract The natural geological and geochemical environment, in addition to providing beneficial mineral content and bioessential elements to groundwaters, may also give rise to undesirable or toxicExpand
Arsenic in rural groundwater in Ghana
Arsenic concentrations in groundwaters from two areas in Ghana, the Obuasi area in the Ashanti region and the Bolgatanga area of the Upper East region vary from 40 m) of weathered regolith andExpand
Mobilisation of arsenic and other trace elements in fluviolacustrine aquifers of the Huhhot Basin, Inner Mongolia
Observed As concentrations in groundwater from boreholes and wells in the Huhhot Basin of Inner Mongolia, northern China, range between <1 μg l−1 and 1480 μg l−1. The aquifers are composed ofExpand
Residence time indicators in groundwater: the East Midlands Triassic sandstone aquifer
The East Midlands Triassic (Sherwood Sandstone) aquifer which has been the subject of detailed radiometric age studies, is used to investigate both inert and reactive constituents of groundwater asExpand
