You nailed it. We have been getting hammered with questions and requests for our thoughts on this because we are on the river. But there really isn't a whole lot of answers. Why can it be sold but told not to catch and consume. No one know what to do. We will have to have some chats Dave. Good job Amanda. Next project biodome.

Very interesting discussion, this makes we ponder about a few things that I'm sure you are probably already aware of that concerns this very mighty, yet vulnerable inland sea. Its interesting to note that if these compounds bioaccumulate, why are they're not advisories for apex predicators like salmon and lake trout? This may point to a recent loading of these contaminants into the waters. Spawning smelt may have been exposed to this in a contaminated tributary. PFAS are commonly used in fire fighting foams, especially for petroleum. It is also interesting to note of the oil refinery fire in Superior Wisconsin on April 26th, 2018. I don't know if these compounds were used to extinguish the fires, but nonetheless it did coincide with the annual smelt spawn in parts of western Lake Superior. I also wonder if toxaphene was secretly used in Lake Superior in an attempt to control the lamprey. Note that cold water lakes contain more toxaphene, as it tends to "gas" less into the atmosphere. Also the big lake has a very long retention time, 200 years or so. Its would be curious to investigate weather climate change may temporarily increase toxaphene levels in Lake Superior, as the "grasshopper effect" may amplify atmospheric deposition into the lake from southerly air masses. As the long warms, it is a possibility that the lakes primary chemical signature may change, as cold water holds on the toxaphene longer. Also studies have looked into the two main compounds to produce chlorinated camphor (toxaphene) which is pine oil and chlorine. Note the pulp mills around The Lake use and produce those exact same ingredients. Because Siskwit Lake on Isle Royale also contains high levels of toxaphene, the study case was closed. The stocking programs of Lake trout and decline of forage fish like smelt and herring could also be responsible for the higher uptake of chemicals in larger fish in the Lake Superior food web.

Lots of questions for sure. Proper terminology would be biomagnification. Which is when toxins accumulate in predators. Bioaccumulation is in regards to an individual fish. There are advisories for larger fish. Just little known information. Kept secret by the commercial fishery lobbyists AKA $$$ AKA to keep Capitalism alive, well, and vibrant. The video after this one goes over some of that information, and where to find it (in Ontario, anyways). And good points about the PFAS and fire fighting, etc. Ontario MNR is requesting samples of smelt from this particular bay, this year, I suspect to test for PFAS and PFOS. There are so many points we could have touched on about toxaphene, lamprey, lake superior turnover, pulp mills, etc. The complication of the whole situation with fish, water and what we've managed to do to destroy it (as humans, and capitalism) is beyond the scope of what could possibly be discussed here. This is just the tip of the iceberg. That hopefully informs at least a few folks to discover what is in their food. Be it wild caught/hunted or purchased in stores.

@@NorthOntarioDave thank you for your reply. Many, including myself, have eaten fish from this lake, so it is concerning, and its frustrating to know that with all the mistakes that were made in the past, just repeat themselves over and over again. That's right, capitalism, greed and the almighty dollar. There has been some interest in the feasibility of developing rainbow trout farms on the north shore, (I believe Nipigon or Black Bay) ,business will capitalize on that as well, and undermine the environmental and health risks involved.

Interesting. I have never eaten smelt. I've caught a couple on hook and line in a lake near Sioux Lookout that had them introduced in the 80s. In Zone 4 and 5 there is no netting season at all, angling is the only legal method of harvesting them here. I wonder if the levels of toxins are less on the west side of Superior like around Thunder Bay for example, is there less bioaccumulation on the upstream side of the lake? Would the concentration increase as the water flows east?
@NorthOntarioDave3 жыл бұрын
It would seem the contaminant is widespread throughout the lake. The US side, west, is also reporting Toxaphene as well as PFAS and PFOS in smelt. Similar advisories there.

@@NorthOntarioDave must be the vast catchment area of the lake, especially if it's coming from the atmosphere. That is sad.

Funny how nutrition labels require brands to specify if they have gluten or milk in their products but not these chemicals.

Thanks for making this video. It truly is eye opening. 👀 But we have so many questions still. ❓❓❓ You mentioned Mexico using these chemicals, and in 1961 in other areas, but maybe there are submerged or buried barrels of these chemicals in the areas surrounding or in this particular bay? Gold mining is one way mercury could get into waters, but what about pulp and paper production? Is there anything being done to locate the source of these chemicals that are found in the fish in this particular bay? See.....we have lots of questions....even more than this....but hopefully something will be done to figure this all out. Thank you for raising awareness about this. It is really important to Anglers as well as commercial fisheries and consumers. Sent you a “YouBoat” (not typing the “S” word, bots don’t like it), and also sending a BIG Like! 😊👍🏻 Great interview!

It was a very common pesticide in North America up until the 1980's. It's still used in other countries. So what's here now is either drifting in the atmosphere from current use in those countries, or its been in the water, soil, etc since the 80's.
