Green Visions: "No more for me, thanks" - no seconds of smelt

Here's what we know: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are getting into Lake Superior and getting into fish.

Here's something else we know: Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are the most common of these chemicals and they bio-accumulate - which means they move through the food chain.

And while we don't know how they're getting into the lake, or how they've getting into smelt, the Wisconsin DNR and Department of Health Services are recommending no more than one serving per month of rainbow smelt.

For more information about PFAS and fish, visit the DNR’s PFAS webpage. For more information on PFAS and associated human health effects, visit the DHS’s PFAS webpage.

 

Lisa Johnson started her broadcast career anchoring the television news at her high school and spinning country music at KWWK/KOLM Radio in Rochester, Minnesota. She was a reporter and news anchor at KTHI in Fargo, ND (not to mention the host of a children's program called "Lisa's Lane") and a radio reporter and anchor in Moorhead, Bismarck, Wahpeton and Fergus Falls.Since 1991, she has hosted Northland Morning on KUMD. One of the best parts of her job includes "paying it forward" by mentoring upcoming journalists and broadcasters on the student news team that helps produce Northland Morning. She also loves introducing the different people she meets in her job to one another, helping to forge new "community connections" and partnerships.Lisa has amassed a book collection weighing over two tons, and she enjoys reading, photography, volunteering with Animal Allies Humane Society and fantasizing about farmland. She goes to bed at 8pm, long before her daughter, two cats, or three dogs.
