An Investigation of Microplastics as a Carrier for Perfluorinated Compounds into Great Lakes Food Webs

This project aims to investigate the potential role of marine plastic debris as a vector for Perfluorinated Compounds (PFAS). Specific research questions are:

  • To what extent do three common plastic types found in the environment act as a sink for select PFASs in Muskegon Lake?
  • How important is the residence time of the materials present in these water bodies concerning the extent of PFAS accumulation?

 


Assessment of Bacterial and Viral Contamination in Burns Ditch and Lake Water in Northwest Indiana

The objectives of this study are to:

  • Study the sources and contamination levels of enteric bacteria and viruses in Burns Ditch, one of the most polluted streams that flow into Lake Michigan in Northwest Indiana.
  • Determine the impact of the pollution of Burns Ditch on the microbial quality of lake front water off West Beach, located three kilometers west of the water outfall.
  • Use a molecular approach to detect viruses in stream and lake waters.
  • Use a computer-based image analysis system to determine the quantity of viruses in water samples.

Estimating the ecological impacts of pharmaceuticals in Lake Michigan

  • Test the acute and chronic effects of cotinine, and triclocarban on aquatic organisms including: green algae (Pseudokirchneriella capricornutum), water fleas (Daphnia magna) and fathead minnows
  • Test the effects of pharmaceuticals and personal care products (PPCPs) detected in Lake Michigan on diatom (Cyclotella meneghiniana) survival
  • Conduct a mixture study chronically exposing D. magna, P.capricornotum, C. meneghiniana, and P. promelas to several PPCPs
