Contamination levels, which the authors say are not a danger to public health, are likely to decline even though cesium has ‘biomagnification’ characteristics, meaning the concentration increases from prey fish to predators when cesium is consumed. That would be offset by the bluefin’s metabolism, which should excrete cesium at a rate of about 2 percent per day |
So that's why those pup sealions are dying. They are eating too many Bluefin tuna
Yeah I figured that Bluefin and even possibly Albacore could end up with some trace contaminants but it's important to note that is because during their migration they fed on bait over there and then migrated here. It's not because the radiation has drifted across the ocean and is now contaminating our waters. I don't know about you but personally I do not catch too many kayak bluefin or albacore. I wish I did
The fish kayakers catch locally are clean and as you state even the most tainted Bluefin your likely to catch offshore is still going to be safe to eat.
So speaking of biomagnification how were the mercury levels in those same Bluefin?
Thanks for the post, and clarification!!!!
