Mercury is a persistent environmental contaminant which, in its characteristic form methyl mercury, can cause neurodevelopmental abnormalities in rodent embryos and neonates. In Texas, hundreds of thousands of waterway acres are contaminated with mercury and other pollutants, and the major source of mercury is emissions from coal-fired power plants.
At “Respectful Insolence”, ScienceBlogger Orac has done a masterful job presenting peer-reviewed research, and debunking anti-vaccination misinformation about (imagined) links between mercury in thimerosol and autism. It seems to me that people who are concerned about mercury and other potential developmental neurotoxins would do better to turn their attention to agricultural and industrial pollutants in the environment.
