Lets just say it would be very difficult. First Mercury is very heavy and buries itself quickly in sand/muck. Second it encapsulates around itself. Third mercury needs really to be in the gas state to be toxic. In burning in coal it cools and about 67 degrees its forming back to a solid. Its not going to float but sink to the bottom-fast. Now the tuna would be bottom feeding or plant feed would have to absorb and raise it for consumption. Now the final part is the toxin would be taken to the tunas liver where toxins are removed slowly. Mercury has a half life of six months meaning every six months half is removed till gone. Cooking raises the temperature to where mercury would vaporize and not be in the tunas liver. I have never yet found any conclusive testing with actual readings of mercury in fish. Just expert opinions.

That has to be one of the dumbest answers I've ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul. Mercury gets into the water and soil as byproducts of burning coal and other fossil fuels. Algae convert it to methylmercury and fish get it from eating the algae. Bigger fish get it from eating the smaller fish that have eaten the algae.
Tuna are predatory fish and retain mercury from the other fishes and squids that it eats. The longer the tuna has been alive, the more mercury it has absorbed. Since the larger tunas are considered to be of higher quality and worth more money, they are targeted more than the younger tunas. There are tunas that are low in mercury such as albacore and smaller yellowfin, the sushi or sashimi grade tunas are larger and have more mercury.
Tuna can have mercury. Just eat it once and a while or just make sure you don't put it in your macoronie only in sandwhiches and stuff me I'm not a big fan of tuna peirod.

tuna
you are not supposed to because of the mercury in the fish.
not very good for you because mercury is in tuna and can cause mercury poisoning to enter the body when eaten too much. well resent studies in 2008 show that the mercury in fish not just tuna fish has stayed the same if not decreased in the past 100 years
No. It complies with international standards for export and consumption.
Fish with high levels of mercury, like tuna and swordfish.
No. Tuna are a fish and fish do not have legs.
from a tuna fish can
predatory fish, Mercury, once ingested never leaves the body, so it is concentrated in the bodies of fish that eat other fish.
You can get four tins of tuna out of one tuna fish.
Large fish, like tuna and swordfish absorb mercury fron environment. Humans and cats then eat the fish. Human waste finds its way back to the sea and is re-absorbed by the fish. So mercury is never truly cleaned out of the environment.
It depends on the kind of Tuna Canned light tuna has about .118 PPM, Albacore is .353 PPM of Mercury If you weigh 120 lbs, one-4 ounce can puts you at about 40% of the daily recommended limit, if you weigh in at 170 lbs, you are at about half that. It takes several months for Mercury to leave your system so it accumulates if you eat the tuna every day or so. The limits are set by the EPA The EPA reference dose (RfD) is defined as the amount of mercury a person, including sensitive subpopulations, can be exposed to on a daily basis over a lifetime without appreciable risk of effects. The EPA RfD is 0.1 µg mercury per kg body weight per day. When using the mercury calculator at GotMercury.Org, this value (adjusted for a week of exposure) is the value to which your mercury levels are being compared. This level corresponds to a blood mercury level of 5.8 ug/L or 5.8 parts per billion (ppb) mercury. Blood mercury levels below this value are considered to be without appreciable risk by the EPA. There is a calculator for most fish at the following website: http://www.mercuryexposure.org/index.php?page_id=36
Fish is good for you but can also contain high levels of mercury and PCB's. Many websites offer analysis's of mercury levels in fish, just search fish + mercury in Google. Fish like tuna and swordfish can contain very highlevels of mercury. I wouldn't go out of your way to eat fish everyday, but make sure you get at least 2 servings of oily fish a week
