The study published in the journal “Ecotoxicology and Environmental Safety” found high concentrations of chemical compounds in the livers of 23 otters in central Illinois.
“Thus otters serve as biomonitors — organisms that contain information on the quantitative and qualitative aspects of the environment — of wildlife exposure,” according to a new study. They also serve as biomonitors for human health because the same toxic chemicals found in otters have also been found in people who eat contaminated fish.
“there are specific watersheds that are areas of concern — not only for otters — for any of the wildlife species that are living in those places, especially those at the top of the food chain.”
