Use of sulfur isotope ratios to determine anthropogenic sulfur signals in a grassland ecosystem
Article Abstract:
The Rothamsed Park Grass Experiment served as a viable environmental monitoring sample for conducting archived soil and herbage analysis. It was shown that Rothamsed's sulfur dioxide emission rate is directly related to the area's herbage S concentration. Although the numerical value representing the herbage variable has decreased considerably from 1900 to 1970, the concentration of total and extractable S in the topsoil were insignificant to the area's pollution rate.

Haze and sulfur emission trends in the Eastern United States
Article Abstract:
The haze and sulfur emission patterns over eastern United States are studied through hourly prevailing daytime visibility observations conducted at 137 sites. The Koschmeider relationship is then applied to the observed visual range to compute for the extinction coefficient and obtain the required trend data set. Results indicate that sulfur emission has no proven effect on the seasonal trends of atmospheric haze over the eastern United States.

Emission inventory and validation
Article Abstract:
Evaluation of Chicago's non-methane organic compound sources by a chemical mass balance (CMB) receptor model is discussed. Eight source categories were used along with the CMB receptor for assessing 23 organics speciated from air samples by gas chromatography. The applicability of CMB to ambient air concentrations of organic compounds and its utility to emission inventory evaluation and validation were demonstrated.
