Influence of H2O on Hg0 Oxidation in the Simulated Flue Gas in Oxygen-Enriched Combustion

16-Jun-2017 | Changxing Hu; Deqiang Hang; Ruitang Guo; Zhiyan Guo; Xiaoyi Yu, Energy & Fuels, 2017

The catalytic oxidation on elemental mercury (Hg0) to water-soluble oxidized mercury (Hg2+) is a good mercury (Hg) control approach for coal-fired power plants, and Hg2+ can be removed by the existing wet flue gas desulfurization (FGD) device. Oxygen-enriched combustion (OEC) is considered as an ...

Ecological Change Drives a Decline in Mercury Concentrations in Southern Beaufort Sea Polar Bears

14-Jun-2017 | Melissa A. McKinney; Todd C. Atwood; Sara Pedro; Elizabeth Peacock, Environmental Science & Technology, 2017

We evaluated total mercury (THg) concentrations and trends in polar bears from the southern Beaufort Sea subpopulation from 2004 to 2011. Hair THg concentrations ranged widely among individuals from 0.6 to 13.3 μg g–1 dry weight (mean: 3.5 ± 0.2 μg g–1). Concentrations differed among sex and age ...
