  • Sulfuryl fluoride: EPA moves to ban pesticide that leaves fluoride behind

    After years of pressure from environmental groups, the Environmental Protection Agency is proposing to ban sulfuryl fluoride by 2014. Sulfuryl fluoride is used to fumigate places where food is stored, and the stuff gets sprayed on grains, dried fruit, coffee, cocoa beans and nuts. The problem with sulfuryl fluoride is that it leaves fluoride behind […]

The cloud of grit from the still-erupting Eyjafjallajokull volcano in Iceland began creeping as far south as Italy, forcing authorities to shut […]

  • Human fluorosis related to volcanic activity: a review

    Abstract: Fluorosis is a widespread disease related to ingestion of high levels of fluorine through water and food. Although sometimes of anthropogenic origin, high levels of fluorine are generally related to natural sources. One of the main sources is represented by volcanic activity, which releases magmatic fluorine generally as hydrogen fluorine through volcanic degassing. For […]

  • Fluoride: Developmental Neurotoxicity.

    Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are 78 studies reporting reduced IQ (75 studies with children and 3 studies with adults) and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit […]
