One of the important environmental issues in upstate New York is the acid rain problem in the Adirondack Mountains, which is associated with atmospheric aerosols. As a part of a systematic study to understand the transport, transformation, and effects of airborne pollutants in the Adirondack Mountains, we are performing an analysis of atmospheric aerosols collected at Piseco Lake. In previous work, we used proton induced X-ray emission (PIXE) [1] spectrometry to measure the concentrations of elements in aerosol samples as a function of the size of the particulate matter. The results of the PIXE analysis indicate significant concentrations of sulfur …

Influence Of Road Salt Deicers On Anaerobic Respiration And Metal Speciation In Soils, Danielle Dupuis
Honors Theses
Road salt deicers, especially NaCl and CaCl2, are used throughout the world on paved areas during the winter. Previous studies suggest that road salt deicers can alter the biogeochemistry of sediment located near roadways and influence the mobility of heavy metals. The goal of this study is to investigate the influence of CaCl2 on wetland soil biogeochemistry, especially trace metal speciation. Sediment cores were collected in the fall from a freshwater wetland near an urban kettle lake (Asylum Lake, Kalamazoo, MI) and incubated for 100 days in deionized water (control), 5 g/L of CaCl2, or …
