This is an interesting finding but there is much danger of over-interpreting from it. Urine mercury has long been known to have little relationship to toxicity problems caused by mercury. The mercury causes harm not from being in the urine but from not being in the urine, due to instead getting bound up in the brain and other organs. There is abundant evidence elsewhere of the major harms being caused by mercury, and this study in no way counters that evidence.
