However, decades of study involving mothers and children in the Seychelles Islands in the Pacific Ocean, where residents consume a wide variety of ocean fish resulting in MeHg exposure that is about 10 times greater than in the populations of the U.S. and Europe, have muddled the scientific consensus. Mercury may combine with carbon or carbon-containing substances to make organic mercury compounds.
