Programmable Thermal Dissociation of Reactive Gaseous Mercury, a Potential Approach to Chemical Speciation:
Programmable Thermal Dissociation (PTD) has been used to investigate the chemical speciation of Reactive Gaseous Mercury (RGM, Hg). RGM was collected on denuders and analyzed using PTD. The technique was tested in a field campaign at a coal-fired power plant in Pensacola, Florida. Stack gas samples were collected from ducts located after the electrostatic precipitator and prior to entering the ...
متن کاملComment on Ernest et al. Programmable Thermal Dissociation of Reactive Gaseous Mercury, A Potential Approach to Chemical Speciation: Results from a Field Study. Atmosphere 2014, 5, 575–596
The authors of this paper utilized a so-called “programmable thermal dissociation method” to monitor HgCl2 emitted from a coal-fired Florida combustion plant. By comparison, they did confirm that the emitted mercury compound was in fact the dichloride, which is in fact the only such plausible molecule for mercury. However, the subtle implications in the paper that the HgCl2(g) molecule is not t...
متن کاملEnvironmental gamma radiation: a comment (Letter to the Editor)
Editor, I read the recent publication by Toossi et al. with a great interest (1). Toossi et al. concluded that “Average gonad and bone marrow doses for North Khorasan, Boshehr and Hormozgan provinces were less than the corresponding values for normal area (2).” There are some facts on this report to be concerned. I agree that the detected levels might be high in the mentioned area, but th...
متن کاملA Fugacity Approach for Prediction of Phase Equilibria of Methane Clathrate Hydrate in Structure H
In this communication, a thermodynamic model is presented to predict the dissociation conditions of structure H (sH) clathrate hydrates with methane as help gas. This approach is an extension of the Klauda and Sandler fugacity model (2000) for prediction of phase boundaries of sI and sII clathrate hydrates. The phase behavior of the water and hydrocarbon system is modeled using the Peng-Robinso...
متن کاملThe Co-Constitution of Health Systems and Innovation; Comment on “What Health System Challenges Should Responsible Innovation in Health Address? Insights From an International Scoping Review”
Lehoux et al provide a timely and relevant turn on the broad and ongoing discussion around the introduction of health technology and innovation. More specifically, the authors suggest a demand-driven approach to health innovation that starts from identifying challenges and demands at the health system level. In this commentary, I review a number of underlying implications of their study in rela...
