A study in 2003 by the Centers for Disease Control and Prevention found that 8% of American women of childbearing age had blood mercury levels exceeding those deemed safe by the U.S. EPA. The possible long-term detrimental effects of occasional exposure to higher levels of mercury and the potentially protective effects of the various nutritional factors contained in fish (e.g., long chain polyunsaturated fats, micronutrients, selenium) may be relevant. While these accidents document the dangers of high levels of mercury, the long-term cumulative effects of exposure to smaller amounts are not well understood, especially during the important and vulnerable period of early development of the central nervous system. Lamers, M.M. 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.

Research conducted by the Seychelles Child Development Studyan international research consortium consisting of University of Rochester and the Seychelles Ministries of Health and Education, Ulster University in Northern Ireland, and the Karolinska Institute in Swedenhas shown that the fatty acids in fish enhance developmental and educational outcomes and may even help protect the developing brain from the harmful effects of mercury. ; Hong, S.

However, exposure mainly occurs through consumption of fish and shellfish contaminated with methylmercury and through worker inhalation of elemental mercury vapours during industrial processes. It becomes airborne when rocks erode, volcanoes erupt and soil decomposes. and J.L.M.N. ; Souza-Monteiro, J.R.; Paraense, R.O. The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. It is therefore the most likely species of mercury to travel long distances from its original source. Depending on the type and amount, exposures to mercury can damage the nervous system, kidneys, liver and immune system.

Mercury exists in various forms: elemental (or metallic) and inorganic (to which people may be exposed through their occupation); and organic (e.g., methylmercury, to which people may be exposed through their diet). The U.S. EPA has issued warnings against eating shark, swordfish, king mackerel, or tilefish and advises limiting the intake of other ocean fish. The Peripheral neuropathy from mercury exposure most commonly involves distal latency sensory slowing for short-term exposures, followed by motor slowing for more long-term exposures. A less common exposure to mercury is when elemental mercury or products containing elemental mercury break and release mercury vapors into the air.
