Lower Colorado River Authority (TX) starts the hunt for more water….

“The Lower Colorado River Authority’s general manager told her 15 bosses that  within five years, she plans to develop 100,000 acre-feet of new water  supplies separate from lakes Travis and Buchanan, the two Hill Country  reservoirs that have been supplying water to much of Central Texas for more  than half a century.” Click here for more….

Woman accused of putting Visine in man’s drinking water…

Here’s a odd stroy….

“A long list of additional charges were filed against a McConnellsburg woman accused of making a man ill by putting Visine eye drops in his drinking water over a three-year period.”

No vinyl chloride in Sauk Village (IL) water

The Illinois  Environmental Protection Agency says vinyl chloride is no longer being  detected in Sauk Village public drinking water supplies so local officials won’t  be required to provide free bottled water to residents.”

High fluoride expsoure is not needed for caries prevention….

G.S. Ingram, E.A. Agalamanyi, S.M. Higham. Caries and fluoride processes. Journal of Dentistry, Volume 33, Issue 3, March 2005, Pages 187–191. Symposium in honour of the work of Professor W M Edgar

Objectives: The purpose of the work was to establish the level and source of salivary fluoride, whether it could interact with tooth mineral and whether it was able to effect calcium re-acquisition and remineralisation.

Methods: Fluoride in saliva and in solution was measured by electrode, calcium by complexometric titration and phosphate colourimetrically—to measure salivary fluoride, its uptake by mineral and the effects of such low levels on calcium and phosphate levels in solution in contact with suspensions of mineral hydroxyapatite.

Results: Fluoride levels in saliva were low but could interact with hydroxyapatite. Such levels caused apatite crystallite growth and preferential acquisition of calcium by calcium-deficient apatite.

Conclusions: Salivary fluoride contents rose with increasing water fluoride levels. It was acquired by hydroxyapatite mineral. Topical fluoride was stored on oral tissues. Even these low fluoride contents could cause mineral crystallite growth with preferential calcium uptake. On a mineral area basis these effects were caused by quite low fluoride uptakes. These findings do not support reliance upon large fluoride uptakes by tooth enamel as evidence for commensurate caries reductions.

Press Spin: Chromium-6 in California drinking water…

The lawsuit filed against the state of California was done for one purpose — get press coverage to make a political impact and raise funding support (click here)…..I’ve seen this too many times to be fooled into thinking it is about health.

The Natural Resources Defense Council has been using this tactic for many years….it is primary funding source…..it allows them to put pressure on government, to claim (falsely) that republicans want dirty water and dirty air. When NRDC’s other environmmental agenda items stall, they always pivot to water….who could be against safe drinking water? Nobody. So it looks like they are doing something good….when in fact, the action is simply a ploy….

 

Fluoride-induced disruption of reproductive hormones in men

Deogracias Ortiz-Pérez, Manuel Rodrı́guez-Martı́nezb, Flavio Martı́nez, Vı́ctor H. Borja-Aburto, Julio Castelo, Juana I. Grimaldo, Esperanza de la Cruz, Leticia Carrizales, Fernando Dı́az-Barriga. Fluoride-induced disruption of reproductive hormones in men. Environmental Research, Volume 93, Issue 1, September 2003, Pages 20–30.

Fluoride-induced reproductive effects have been reported in experimental models and in humans. However, these effects were found in heavily exposed scenarios. Therefore, in this work our objective was to study reproductive parameters in a population exposed to fluoride at doses of 3–27 mg/day (high-fluoride-exposed group—HFEG). Urinary fluoride levels, semen parameters, and reproductive hormones in serum (LH, FSH, estradiol, prolactin, inhibin-B, free and total testosterone) were measured. Results were compared with a group of individuals exposed to fluoride at lower doses: 2–13 mg/day (low-fluoride-exposed group—LFEG). A significant increase in FSH (P<0.05) and a reduction of inhibin-B, free testosterone, and prolactin in serum (P<0.05) were noticed in the HFEG. When HFEG was compared to LFEG, a decreased sensitivity was found in the FSH response to inhibin-B (P<0.05). A significant negative partial correlation was observed between urinary fluoride and serum levels of inhibin-B (r=−0.333, P=0.028) in LFEG. Furthermore, a significant partial correlation was observed between a chronic exposure index for fluoride and the serum concentrations of inhibin-B (r=−0.163, P=0.037) in HFEG. No abnormalities were found in the semen parameters studied in the present work, neither in the HFEG, nor in the LFEG. The results obtained indicate that a fluoride exposure of 3–27 mg/day induces a subclinical reproductive effect that can be explained by a fluoride-induced toxic effect in both Sertoli cells and gonadotrophs.

 

Fluoride effects on the central nervous system…

L. Valdez-Jiménez, C. Soria Fregozo, M.L. Miranda Beltrán, O. Gutiérrez Coronado, M.I. Pérez Vega. Effects of the fluoride on the central nervous system. Neurología (English Edition), Volume 26, Issue 5, 2011, Pages 297–300.

Introduction: Fluorine (F) is a toxic reactive element and exposure to it passes almost unnoticed with the consumption of tea, fish, meat, fruits, etc. and articles in common use such as: toothpaste additives; dental gels, non-stick pans and razor blades as Teflon. It has also been used with the intention of reducing dental caries.

Development: Fluoride can accumulate in the body, and it has been shown that continuous exposure to it causes damaging effects on body tissues, particularly the nervous system directly without any previous physical malformations.

Background: Several clinical and experimental studies have reported that F induces changes in cerebral morphology and biochemistry that affect the neurological development of individuals as well as cognitive processes, such as learning and memory.

F can be toxic by ingesting one part per million (ppm), and the effects are not immediate, as they can take 20 years or more to become evident.

Conclusion: The prolonged ingestion of F may cause significant damage to health and particularly to the nervous system. Therefore, it is important to be aware of this serious problem and avoid the use of toothpaste and items that contain F, particularly in children as they are more susceptible to the toxic effects of F.
