Reply to comment by chrisdh79 in Magnetic solution removes toxic "forever chemicals" from water in seconds by chrisdh79

This is incredible. A recent study I read found extremely high levels of PFOS/PFOA in lake and river fish through out the US. Here are a few tidbits from that study: -Consuming 1 fish is the equivalent to drinking water that is 12,000x the safe limit for PFOS for a month straight -The average fish fillet was found to contain 11,800 ng/kg PFOS from the great lakes, the lifetime safe limit is 0.004 ng/kg. That's 2,950,000x the safe lifetime limit for the consumption of one fish.

This is something that needs immediate attention and had me staying away from fish. One thing to note is the study did collect most samples from bass close to larger populations, but still the results are alarming.

Are they high in all fish in the world? Or mainly lakes in the US?

I buy farmed salmon from Scotland, I'm wondering if they're high in that

Stay away from fish farmed near military bases or airports. Otherwise you’re probably fine.

PFOS/PFOA has been used rigorously in so many products for 70ish years. It really is in everything. I work in environmental consulting and when we sample for it I need to make sure staff don't shower the day before as a lot of shampoos/body washes have PFOS/PFOA in it, you can't wear waterproof jackets, the list goes on. The fact is it's bioaccumulating in fish (along with many persistent pollutants) which makes sense as rivers/streams/oceans is where our waste ends up. Even though I live on the west coast of Canada, far from where the study was conducted, even if the fish here have a fraction of the amount of PFOS/PFOA that is still way past the lifetime limit according to the EPA.

But really if it's not this contaminant in fish it's something else I suppose. Depressing but is anything really clean anymore?

Yeah I was thinking the same, we are being poisoned in one way or another and there's no avoiding pollutant, there's always something, we just have to hope our bodies are able to remove some of the burden in order to not become sick, very depressing times we live in.

And thanks for your comment, it looks like I'll be ditching my salmon I eat, sad times.

I wonder if I can find a lab that tests for this and send a sample of the salmon I buy to them, i guess any amount is too much tho so results will still mean I can't eat it

I checked and my water filter removes 99% of them so that's a start I guess

I'm curious what water filter you have, as many don't remove these chemicals.

It's a Zero water filter, Zero is the brand, there's tests proving it to remove heavy metals, micro plastics and also PFOS / PFOA.

A Reverse osmosis system will remove them too if you want to go hardcore on your filtering system

Wouldn't this make the fish great filters? Would the fish be more economical to use that the magnetic liquid?

You'd have to remove the fish from the foodchain/ecosystem once they absorbed the chemicals in that case (and not eat them), which is probably not feasible or ideal.

Well, then what do we do with the fish? Just not sell it to customers? That'd put a big strain on the fishing industry, which may push them to cut corners and do more ecological damage to the environment to make ends meet

Breed them for more filter fish then dispose of them? Idk, just a thought that I haven't put any time into

It's good to talk things out to help develop ideas. What if the fish become invasive, for example? It invariably happens, see all the times we accidentally introduced X species (usually rat) to non-native lands, then intentionally introduced Y species (bird or cat most often) to deal with X, and instead X and Y are both flourishing, devastating the local ecosystem.

Biological solutions are almost always dangerous and difficult to control like that, unfortunately.

Magnets don't reproduce, so generally there won't be magnet-outbreaks, you know?

Catch the fish, process the concentrated chemicals out of them, then sell the fish.

Stick magnets on the fish

Then take the contamination from the fish that gets sucked out by a magnet and shoot it into outer space.
