Total chromium and hexavalent chromium occurrence analysis
Journal AWWA, 2013 Total and hexavalent chromium occurrence in the United States was investigated using three available datasets. The National Chromium and Boron Occurrence Survey, the US Environmental Protection Agency database of chromium from the Second Six‐Year Review, and California Department of Public Health water quality analysis data were obtained and analyzed ...

Accurate many-body electronic structure near the basis set limit: Application to the chromium dimer [PDF]
, 2020 We describe a method for computing near-exact energies for correlated systems with large Hilbert spaces. The method efficiently identifies the most important basis states (Slater determinants) and performs a variational calculation in the subspace ...

Fume generation and content of total chromium and hexavalent chromium in flux-cored arc welding. [PDF]
The Annals of Occupational Hygiene, 2003 This study was performed to investigate the fume generation rates (FGRs) and the concentrations of total chromium and hexavalent chromium when stainless steel was welded using flux-cored arc welding (FCAW) with CO2 gas. FGRs and concentrations of total chromium and hexavalent chromium were quantified using a method recommended by the American Welding ...

Geochemistry of reduced inorganic sulfur, reactive iron, and organic carbon in fluvial and marine surface sediment in the Laizhou Bay region, China [PDF]
, 2015 Understanding the geochemical cycling of sulfur in sediments is important because it can have implications for both modern environments (e.g., deterioration of water quality) and interpretation of the ancient past (e.g., sediment C/S ratios can be used ...
