Spectroscopic and Microspectroscopic Investigation of Arsenic Speciation and Distribution in Mine Wastes
ثبت نشده
چکیده
Residential developments near former mining regions in southern California face potential environmental and health risks due to the weathering of arsenic-bearing deposits and mine wastes. Fine-grained particles possessing elevated concentrations of arsenic from these areas can be easily transported by water and dispersed by wind. Understanding the speciation of arsenic is essential to evaluating mobility and geoavailability because certain species of arsenic are more toxic and mobile than others. Speciation involves identifying the composition and relative proportions of chemical compounds present within a sample.

Spectroscopic Based Quantitative Mapping of Contaminant Elements in Dumped Soils of a Copper Mine
Possibility of mapping the distribution of Arsenic and Chromium in a mining area was investigated using combination of (VNIR) reflectance spectroscopy and geostatistical analysis. Fifty five soil samples were gathered from a waste dump at Sarcheshmeh copper mine and VNIR reflectance spectra were measured in a laboratory. Savitzky- Golay first derivative was used as the main pre-processing metho...

متن کاملSpeciation and distribution of arsenic and localization of nutrients in rice grains.
Arsenic (As) contamination of rice grains and the generally low concentration of micronutrients in rice have been recognized as a major concern for human health. Here, we investigated the speciation and localization of As and the distribution of (micro)nutrients in rice grains because these are key factors controlling bioavailability of nutrients and contaminants. Bulk total and speciation anal...
متن کاملArsenic-Microbe-Mineral Interactions in Mining-Affected Environments
The toxic element arsenic (As) occurs widely in solid and liquid mine wastes. Aqueous forms of arsenic are taken up in As-bearing sulfides, arsenides, sulfosalts, oxides, oxyhydroxides, Fe-oxides, -hydroxides, -oxyhydroxides and -sulfates, and Fe-, Ca-Feand other arsenates. Although a considerable body of research has demonstrated that microbes play a significant role in the precipitation and d...
متن کاملAssessing the influence of compost and biochar amendments on the mobility and toxicity of metals and arsenic in a naturally contaminated mine soil.
Amending contaminated soils with organic wastes can influence trace element mobility and toxicity. Soluble concentrations of metals and arsenic were measured in pore water and aqueous soil extracts following the amendment of a heavily contaminated mine soil with compost and biochar (10% v:v) in a pot experiment. Speciation modelling and toxicity assays (Vibrio fischeri luminescence inhibition a...
