Overview
Investigators from the University of Notre Dame conducted a 42-year study using biological records from the Great Lakes. The research focused on tracking the movement of per- and polyfluoroalkyl substances (PFAS) within the region. The analysis indicated the presence of these chemicals, often referred to as 'forever chemicals,' in multiple wildlife species inhabiting the Great Lakes.
Research Context
The study specifically addressed the movement of per- and polyfluoroalkyl substances (PFAS) through the Great Lakes environment. These compounds are known for their persistence. The research utilized an extensive historical dataset, biological records, covering over four decades to understand the long-term presence and distribution of PFAS in the ecosystem.
Approach
The research methodology involved the analysis of 42 years of biological records originating from the Great Lakes. This long-term dataset allowed for a comprehensive assessment of how PFAS have moved within the region. The researchers examined these records to identify the presence and patterns of contamination by PFAS in various wildlife populations.
Findings
The study indicated that per- and polyfluoroalkyl substances (PFAS) have moved across the Great Lakes region. The analysis of the biological records from 1980 onwards revealed contamination by these chemicals in a variety of wildlife species. The duration of the study, 42 years, provided a historical perspective on the dispersal and accumulation of PFAS within the Great Lakes ecosystem.
