Composition and origin of summertime air pollutants at Deep Creek Lake, Maryland
(Elsevier, 1989)
A 1 month intensive summertime field study conducted in rural western Maryland resulted in a comprehensive set of fine particle, gaseous and meteorological data. Sulfur in the assumed form of ammonium sulfate accounted for ...
Sulfur gases produced by the decomposition of sulfide minerals: Application to geochemical exploration
(Elsevier, 1982-12)
We have evaluated the potential application of sulfur gas analysis to exploration for buried sulfide mineral deposits by: (1) calculating by use of equilibrium thermodynamics, the relative abundances of gases that should ...
Atmospheric acidity measurements on allegheny mountain and the origins of ambient acidity in the Northeastern United States
(Elsevier, 1989)
Atmospheric acidity as HNO3(g), SO2(g), and aerosol H+ was measured on Allegheny Mountain and Laurel Hill in southwest Pennsylvania in August 1983. The aerosol H+ appeared to represent the net after H2SO4 reaction with ...
Effect of ambient humidity on dichotomous sampler coarse/fine ratios
(Elsevier, 1988)
Atmospheric aerosols were measured in August 1983 on Allegheny Mountain and Laurel Hill in southwestern Pennsylvania. Ambient humidity was observed to influence the coarse to fine particle ratios as determined by dichotomous ...
Application of fluid inclusion and rock-gas analysis in mineral exploration
(Elsevier, 1986-03)
Gases are known to form haloes around presently active geothermal systems and might be useful in exploration for older, extinct hydrothermal systems. Gases from such extinct hydrothermal systems can be liberated for analysis ...
Extractable organic compounds in midwest rain and snow
(Elsevier, 1982)
A portion of the organic compounds in subaqueous sediments originates from airborne materials transported from distant sources. We have analyzed by GC and GC-MS the organic compounds extractable with dichloromethane in ...
