In order to characterize ambient levels of vapor phase and particle mercury at source and receptor locations in the Great Lakes Basin, and to diagnose source regions of atmospheric mercury, samples were collected at three locations: Illinois Institute of Technology (ITT) in Chicago, IL and South Haven, MI (SHA) and aboard the R/V Laurentian (LAU). Vapor phase mercury samples were collected onto gold-coated sand traps and analyzed by cold vapor atomic fluorescence (CVAFS). Particulate phase mercury samples were collected onto both Teflon filters and prefired glass fiber filters. Teflon filters were analyzed by neutron activation analysis (NAA) and glass fiber filters were analyzed by CVAFS after acid digestion/extraction. Results of particle phase analysis from glass fiber filter samples and results of vapor phase mercury samples are presented here.
