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 ...
Estimation and Mapping of Wet and Dry Mercury Deposition Across Northeastern North America
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2005-03)
Whereas many ecosystem characteristics and processes influence mercury accumulation in higher trophic-level organisms, the mercury flux from the atmosphere to a lake and its watershed is a likely factor in potential risk ...
Trajectory sensitivity to rawinsonde data resolution
(Elsevier, 1988)
Meteorological measurements collected during the Cross Appalachian Tracer Experiment (CAPTEX) were used to evaluate the sensitivity of trajectory calculations to variations in the spatial and temporal density of rawinsonde ...
On the variability of simulated source-receptor relationships for sulfur deposition
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1986-10)
The use of Lagrangian models to estimate source-receptor relationships for ambient SO 4 = concentrations and S deposition has become fairly widespread over the past several years. This paper addresses the sensitivity of ...
Incubation in cyclohexene decomposition at high temperatures
(John Wiley & Sons, Inc., 1990-02)
A detailed master equation simulation has been carried out for the thermal unimolecular decomposition of C 6 H 10 in a shock tube. At the highest temperatures studied experimentally [J. H. Kiefer and J. N. Shah, J. Phys. ...
Multiple-Well, multiple-path unimolecular reaction systems. I. MultiWell computer program suite
(John Wiley & Sons, Inc., 2001-04)
Unimolecular reaction systems in which multiple isomers undergo simultaneous reactions via multiple decomposition reactions and multiple isomerization reactions are of fundamental interest in chemical kinetics. The computer ...
Patterns of Mercury Deposition and Concentration in Northeastern North America (1996–2002)
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2005-03)
Data from 13 National Atmospheric Deposition Program Mercury Monitor Network (NADP/MDN) monitoring stations (1996–2002) and the Underhill (VT) event-based monitoring site (1993–2002) were evaluated for spatial and temporal ...
Detection of oxidative mutagens in an urban air-particulate extract: a preliminary study
(Elsevier, 1992-12)
The Ames assays strains TA98 and TA100 have been useful in characterizing complex mixtures from organic solvent extracts of particles from diesel-powered vehicles, ambient air, and other sources. In this paper we report ...
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 ...
Mercury Air/Surface Exchange Kinetics of Background Soils of the Tahquamenon River Watershed in the Michigan Upper Peninsula
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-02)
Air/surface exchange of mercury was investigated over background soils at five sites in the Tahquamenon River watershed in the Michigan Upper Peninsula in the summer of 1998. Measurements of Hg fluxes were performed during ...
