Abstract Details

2007, Master of Science (MS), Ohio University, Chemical Engineering (Engineering).
The study characterized the temporal variation of the ambient mercury species (GEM, RGM, and Hgp) measured at a rural site in the Ohio River Valley area from July 2004 to May 2006. Source-receptor relationships of the mercury species were evaluated by utilizing principal component analysis (PCA). The influence of meteorological parameters (temperature, wind speed, relative humidity, barometric pressure, and solar radiation flux) on mercury concentration was studied statistically. Three patterns of mixing height change and the mercury concentration variation were identified and elaborated. Multiple linear regression was used to quantify the collective impacts of meteorological conditions on mercury concentration. The ratio of RGM /Hgp was investigated in relation to the mercury transport. Conditional probability function (CPF) was applied to evaluate the directional contributions of possible mercury sources. Potential source contribution function (PSCF) was employed to identify the potential RGM source regions. The results of CPF and PSCF were found to be in relatively good agreement.
