(2009-05-15)The objective of this research was to investigate the retention of arsenate (iAsV), arsenite (iAsIII), monomethyl arsenate (MMAsV) and dimethyl arsenate (DMAsV) by calcite and assess the impact of dissolved Ca2+, Mg2+, ...
-
(Texas A&M University, 2005-08-29)Given that the mobility, bioavailability, and toxicity of arsenate in natural systems is often controlled by the strong binding capacity of iron oxyhydroxides, the objective of this study was to document the interactions ...
-
(Texas A&M University, 2004-11-15)The characterization of water treatment residuals containing arsenic was investigated in the first study. Arsenic desorption and leachability from the residuals were the focus of this study. Arsenic leaching from water ...

(2020-06-29)Recovery of injected water is one of the most important aspects of an aquifer storage and recovery (ASR) system and is determined by hydrogeologic, operational, and chemical factors. A common series of reactions resulting ...

(Texas A&M University, 2005-11-01)Extraction with sodium phosphate has been used as a method of accessing arsenic in soils. Arsenic extraction efficiency by phosphate from rice-paddy soils of Bangladesh usually has been low and highly variable between ...

(2009-05-15)Neural tube defects (NTDs) are malformations affecting about 2.6/1000 births worldwide, and 1/1000 in the United States. Their etiology remains unknown, and is likely due to interaction of genetic susceptibility factors ...
-
(2009-05-15)Sulfide minerals have been suggested to play an important role in regulating dissolved metal concentrations in anoxic environments. Pyrite is the most common sulfide mineral and it has shown an affinity for arsenic, but ...
-
(Texas A&M University, 2005-08-29)Arsenic is a toxic element that is widely distributed throughout the earth??s crust as a result of both natural geologic processes and anthropogenic activities. In virtually all environments, methylated forms of arsenic ...

Mineralogy and Geochemistry of Pb, Zn and Ag Mine Tailings Originating From Carbonate-Rich Deposits (2012-11-29)Mining for silver, lead, zinc, and copper in Zimapan, Hidalgo State, Mexico has been ongoing since 1576. Unsecured tailings heaps and associated acid mine drainage have presented problems related to soil quality, water ...
-
(2020-06-23)Apatite was added to a soil highly contaminated with As and Pb to enhance As uptake by the hyperaccumulating fern, Pteris cretica. Arsenic and lead co-contamination is common in smelter soils and can be a major source of ...

(Texas A&M University, 2004-09-30)Potential arsenic toxicity in different geologic environments is dependent on total arsenic concentration and arsenic bioavailability. It is important to identify the geologic environments that may sequester arsenic because ...
