Sea Vegetables & Mercury



Several people have asked me about the threat of mercury in sea vegetables. Like arsenic, it is possible that sea vegetables can absorb mercury. But, the mercury levels are nowhere near what you would find in swordfish, tuna or other large fish. Awhile back it was found that sea vegetables from Norway and Japan both contained small amounts of mercury, but the levels were such that it was considered safe.
