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:
