Fluoride is absorbed by plants through the stomata as they take in air and through roots when they absorb water, but itis not very mobile in plants. When absorbed through roots, much of it stays in the root. Fluoride that reaches a leaf usually stays there and migrates to the tip and ...
aIn water, inorganic fluorides usually remain in solution (as fluoride ions) under conditions of relatively low pH and hardness as well as in the presence of ion-exchange materials such as bentonite clays and humic acids (Pickering et al., 1988). 在水中,无机氟化物在解答通常保持(当氟化物离子...
Fluoride occurrence in ground water is a natural phenomenon, influenced by the local and regional geological setting and hydrogeological conditions of the region. Fluoride content much higher than the maximum permissible limit has been found in many regions throughout the world. The problem assumes mor...
Fluoride is now also being detected among the chemicals being sprayed in the atmosphere usinggeo-engineering,(also calledchemtrails.In addition to almost universal exposure to drinking it and consuming it in food products made with water, we are now breathing the fluoride as well, along with sever...
When asked about this potential change in an NBC interview Trump said, "Well, I haven't talked to him about it yet, but it sounds OK to me." So, what are the health benefits of fluoride in water, and what would removing it mean?
The U.S. has been adding fluoride to water since 1950, when the federal government endorsed the practice as a way of preventing tooth decay and cavities. Neil Maniar, director of Northeastern University's Master of Public Health program and professor of practice in public health, says fluoridati...
The As and F contamination results from water–rock interactions and may be accelerated by geothermal and mining activities, as well as by aquifer over-exploitation. These types of contamination are particularly pronounced in arid and semi-arid regions, where high As concentrations often show a ...
