My research group is poised at the forefront of research on plastic pollution within freshwater ecosystems, in general, and the Laurentian Great Lakes, more specifically.
Fredonia lies 2 miles from the shores of Lake Erie, one of the 5 Great Lakes, which in total comprise the largest freshwater ecosystem in the world. In collaboration with the 5 Gyres Institute, we conducted the first-ever survey for plastic pollution within the open-waters of the Great Lakes. Not surprisingly (given the abundance of plastic within the world's oceans) we have found plastic particles within all 5 of the Great Lakes. The counts obtained, especially those within Lakes Erie and Ontario, rival those within the world's ocean. Even further, what surprised us the most is the size of the particles we found. To date ~75% of the plastic we skim off the surface of the Great Lakes is between one third and one millimeter in diameter. Tiny. We have had several (hundred) news reports as a result of our work. Here are links to a few:
As extensions of our initial Great Lakes Plastic Pollution Surveys (2012-2014) we have conducted additional research projects within Wastewater Treatment Facilities, major tributaries to the Great Lakes, Great Lakes fisheries, San Francisco Bay, and Lake Hovsgol (in Mongolia). We are currently involved in a joint research project with the USGS and the Milwaukee Metropolitan Sewer District, a feeding and degradation study supported through New York Sea Grant, as well as our on-going collaboration with Inland Seas.
We hope to slowly build up an understanding of the types and abundance of plastics within the Great Lakes and other freshwater systems, laying the groundwork for important additional investigations into their ecosystem impacts.
In addition to the above, my background is in atmospheric kinetics and the impact of combustion emissions. As such my research group has previously conducted research projects on the impact of forest fires on atmospheric chemistry, computational model development, computational chemical analyses, smog chamber studies, food waste analyses and biogas production studies.
