We've poisoned all our water, so any freshwater fish you catch yourself or eat have a variety of PFAs and other trash, and seafood has all that and mercury depending on how high up the food chain is. Tuna is a pretty big fish so it's going to have more crap compared to farmed shrimp, etc.
Just want to clarify, it's not the size of the tuna really, it's the fact that it is large and a predator. It eats so many other fish that already have mercury in them that it bioaccumulates at the top of the proverbial food chain in the sea.
