>>11187907They must have accounted for the half-life of methylmercury when deciding 2 ppb is the limit for drinking water. Although, it sounds very high. 16 fluid ounces is about 450 grams, and you need about 4 of those each day as an average sized adult, or 1800 grams. 0.5 micrograms/kg/day is not close at all. I'm 50kg, so 25 micrograms is "safe", yet they allow up to 2 micrograms/gram, or 3600 micrograms per day in 64 fluid ounces of drinking water? Even one 5 ounce can of albacore tuna would contain ~50 micrograms.
