Good News For Lake Superior Anglers As PFAs Decrease
We all need a little good news these days, right? I'm happy to share with you some progress that has been made on an environmental push on the Great Lakes. A recent study has shown that our fish in the Great Lakes are becoming safer to eat.
PFAs 'Forever Chemicals'
By now, you've probably heard of 'forever chemicals.' These are chemicals used by companies that make consumer products like carpets, cosmetics, clothing, teflon, cookware, and other things. The actual name of PFAs is polyfluoroalkyl and perfluoroalkyl substances.
MPR reports the good news is that the PFAs found in Great Lakes fish have decreased, and have been steadily dropping since measures were taken to phase out the use of PFAs. They were first discovered in the 1990s, and much of the PFAs had been phased out by the early 2000s.

What harm is caused by PFAS?
These forever chemicals never break down and can cause harm to people. It can weaken a person's immune system, increase a person's risk of cancer, cause liver and thyroid issues, and have other harmful effects.
PFA Levels Dropping, But Will They Continue?
PFAs are going down, and the fish are safer to eat than they were before. But experts warn that even reduced levels of PFAs can still cause harm. That's why the recommendation is still no more than one rainbow smelt serving per week from Lake Superior.
It's too early to tell if the decline in levels will continue or if they will stall.
