Research Interests
Dr. Holsen's research interests include the transport, transformations and fate of hydrophobic organic chemicals, metals, and ions in a wide array of environmental systems. Of particular interest is pollutant exchange (wet deposition, dry deposition and air-surface/air-water exchange) between earth's surface and the atmosphere. Below are several current project areas.
Lake Ontario Atmospheric Deposition Study (LOADS)
The atmosphere is a significant source of pollutants to the Great Lakes. In this project the amount of pollutants entering Lake Ontario from the atmosphere associated with rainfall, particle deposition and the gas-phase are being measured with a combination of shore-line sampling and ship based sampling.
Atmospheric Deposition, Transport, Transformations and Bioavailability of Mercury across a Northern Forest Landscape
Widespread contamination of mercury in remote aquatic environments due to atmospheric deposition and consequent high concentrations in aquatic biota, suggest that there is an acute need to improve understanding of the mechanisms of mercury transport and transformations in lake/watershed ecosystems. The goal of this interdisciplinary project it to develop a better understanding of how atmospherically deposited mercury is transported through an entire watershed system. Results from field and laboratory experiments will be used to improve an existing mercury transport model.
In-State/Out-of-State Sources of Semivolatile Pollutants and Hg in New York State
The objective of this research is to measure the concentration of airborne particulate matter including its semivolatile components, for example, nitrate, polyaromatic hydrocarbons (PAHs), as well as mercury, at two locations in NYS and determine the impact of in-State and out-of-State power plants and other sources on those concentrations
