The risk from consuming mercury by eating fish and shellfish may include harm to an unborn baby or a young child's developing nervous system if the mercury levels are high enough. Canned tuna and cod are the exceptions. While re-emission accounts for the largest proportion of emissions, it is likely that the mercury emitted from these sources originally came from anthropogenic sources. The effects of these different sources of mercury have been studied at the Experimental Lakes Area in Ontario, Canada, using research procedures including whole-lake ecosystem experiments and non-lethal fish muscle biopsies.[8]. [37] However place-based approaches do not take into account cases of severe mercury poisoning, such as that found in Minamata disease. Annually, Italy catches approximately a third of its fish from the Adriatic Sea, where these anglerfish were found. The American College of Obstetricians and Gynecologists noted that, considering all the dangers and benefits, the overall result of eating fish in the United States is likely to improve personal health rather than damage it. Non-point sources include floods that create hospitable habitats for bacteria that can convert mercury to methylmercury, which is the toxic form that bioaccumulates through aquatic food webs. Mercury levels in the northern Pacific Ocean have risen about 30 percent over the past 20 years and are expected to rise by 50 percent more by 2050 as industrial mercury emissions increase, according to a 2009 study led by researchers at the U.S. Geological Survey and Harvard University.
