Mercury concentrations in hair exposed in vitro to mercury vapor

Biological Trace Element Research, 1993
Hair is often used as an index of environmental and industrial exposure to different metals. The interpretation of metal levels in hair is difficult because of the risk of external contamination. The aim of this study was to define the degree of external contamination of hair exposed in vitro to mercury vapor.

Power from Mercury Vapor

Transactions of the American Institute of Electrical Engineers, 1913
The author describes a thermodynamic process using a mercury boiler in tandem with a steam-generating apparatus for the production of power. As mercury boils at 677 deg. fahr. at atmospheric pressure and condenses in a 28-in. vacuum at 455 deg. fahr., its temperature and pressure characteristics make possible the utilization of some of the energy ...

The Viscosity of Mercury Vapor

Physical Review (Series I), 1896
The uncertainty which attaches to the specific heat ratio of gases as a means of distinguishing between monatomic and polyatomic molecules has been recently made evident by the extended discussions of the sig nificance of that property in connection with the atomic weights of argon and helium.

Mobility of Mercury Ions in Mercury Vapor

Physical Review, 1964
Measurements of mercury ion drift velocities and mobilities in mercury vapor by the Hornbeck technique have been made over a range of electric-field strength divided by reduced pressure ($\frac{E}{{p}_{0}}$) from 40 to 1500 V / (cm\ifmmode\times\else\texttimes\fi{}mm Hg). Two stable mercury ions, believed to be ${\mathrm{Hg}}^{+}$ and $\mathrm{Hg}_{2}^{

The phytotoxicity of mercury vapor

Water, Air, and Soil Pollution, 1984
Seed germination and early growth were unexpectedly resistant to Hg-vapor at air saturation levels (14 μg L−1). Among 15 species and cultivars tested, inhibition of shoot or root growth in excess of 50% was not seen, but occasional stimulation was noted.

Mercury-Vapor Detector

Applied Spectroscopy, 1971
A simple and inexpensive accessory to an atomic-absorption spectrometer can be built which permits one to determine 1–300-ng quantities of mercury in various types of samples without any prior chemical treatment. The detector has been used with samples of sediments, rocks, coals, tissues, and waters, and is especially suited for mercury pollution ...

The Mercury-Vapor Process

Journal of Fluids Engineering, 1942
Abstract This paper is a brief history of the development of the mercury-vapor process from the first tube tested in 1912 to the latest 20,000-kw unit at the Kearny Station of the Public Service Electric & Gas Company. A typical cycle and a temperature-entropy diagram show how a better efficiency is obtained by raising the boiling ...
