Hair as a biomarker of fluoride exposure

An interesting exploratory study. More investigation along this line of thought is needed.

N Parimi, V Viswanath, B Kashyap, PU Patil. Hair as biomarker of fluoride exposure in a fluoride endemic area and a low fluoridated area. Int J Trichology. 2013 Jul;5(3):148-50. doi: 10.4103/0974-7753.125613.

AIM: The aim of the present study was to determine whether hair could be used as biomarker of fluoride exposure.

MATERIALS AND METHODS: The study was carried out on 30 people living in an endemically fluoridated area and a low fluoridated area. Samples of hair from the occipital were taken and subjected to fluoride analysis by a fluoride ion electrode.

RESULTS: Lower fluoride levels in water supplies correlated with lower levels of fluoride in hair and more over higher fluoride levels in water correlated with higher levels of fluoride in hair. A direct relationship was evident between fluoride levels in water supplies and concentration of fluoride in hair (P < 0.01).

CONCLUSIONS: The results of the present study indicate hair can be used as an indicator of fluoride exposure.

LEED-certified buildings use more energy?

Not sure what to make of this but I am posting it here for your information.

Acadamies report on “climate change” reads like propaganda

This is sad to see and indeed unfortunate. This report is not based on science, but on getting a particular message out. It reads like a government agency report looking for funding justification. When evaluating public relations reports such as this remember: “Saying so does not make it so.”
