Evaluation of extraction methods for hexavalent chromium determination in dusts, ashes, and soils
Ruth E. Wolf, Stephen A. Wilson
2010, Open-File Report 2010-1243
One of the difficulties in performing speciation analyses on solid samples is finding a suitable extraction method. Traditional methods for extraction of hexavalent chromium, Cr(VI), in soils, such as SW846 Method 3060A, can be tedious and are not always compatible with some determination methods. For example, the phosphate and high...

Dina Venezky, Stephen Wessells
2010, Open-File Report 2010-1174
Carbon dioxide is a dangerous volcanic gas. When carbon dioxide seeps from the ground, it normally mixes with the air and dissipates rapidly. However, because carbon dioxide gas is heavier than air, it can collect in snowbanks, depressions, and poorly ventilated enclosures posing a potential danger to people and other...
