Water treatment process called potential risk
Maas and Patch, co-directors of the Environmental Quality Institute at UNC-Asheville, said their research showed that a combination of chloramines and fluorosilicic acid, especially with extra amounts of ammonia, increases lead leaching.
Fluoride Chemicals Leach Lead into Water Supplies
Fluoride chemicals, combined with other water additives, pull health-damaging lead from plumbing systems into drinking water, according to University of North Carolina researchers reported a North Carolina newspaper on May 18, 2005 (a). Fluoride is added to water supplies to prevent cavities, not purify it as some believe. A combination of chloramines and fluorosilicic acid, […]
Effects of Water Fluoridation on Teeth: Dental Fluorosis vs. Tooth Decay
From a risk/benefit perspective, water fluoridation is an unacceptably risky practice — a fact that is evident even if teeth are the only tissue in the body that one considers. Modern research shows that fluoride ingestion (from water alone, or all sources combined) is far more likely to cause teeth to develop fluorosis than it is to prevent a cavity. As […]
Mapping Urban Food Deserts
Two Michigan State University professors have developed interactive maps that offer a visual perspective of urban food deserts. By using GIS (geographic information systems) technology, they are showing, rather than simply telling, how urban residents are losing access to fresh produce and balanced nutrition.
The Health PAC to Watch? Dentists
The American Dental Association wants to preserve its members’ monopoly on fixing cavities and are battling to prevent other health-care providers from doing “drill and fill” or setting up their own teeth-cleaning practices.
Low-Cost Dental Care Ignites Wide Debate
A new study has reignited the debate over which practitioners are qualified to provide dental care, especially to underserved populations in high-poverty areas. It found that Alaska’s dental therapists provide “safe, competent, appropriate” care. (The therapists refer cases beyond their scope to supervising dentists.)
New Hampshire Passes First State-Wide Fluoride Warning Law
Beginning August 4, 2012, New Hampshire will require notification that 6-month-olds should not be routinely fed infant formula mixed with fluoridated water to avoid discoloring babies’ unerupted teeth (fluorosis), reports the Fluoride Action Network (FAN). Passed by the House, 253-23, unanimously by the Senate, and signed by the Governor, HB-1416 reads: “If a public water […]
Harvard Study Finds Fluoride Lowers IQ
Harvard University researchers’ review of fluoride/brain studies concludes “our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.”
Fluoridation, Cancer: Did Researchers Ask the Right Questions?
WHEN HEALTH OFFICIALS decided to add fluoride to the water supply of Grand Rapids, Mich., in 1945, they plunged ahead despite the lack of a rigorous, large-scale study of the risks and benefits. And for most of the next 60 years, fluoridation research has gone pretty much like that. It has not been science’s finest […]
Puberty Before Age 10: A New ‘Normal’?
Was the age of puberty really dropping? Parents said yes. Leading pediatric endocrinologists said no. The stalemate lasted a dozen years.
