How can fluoride residual water cause poisoning?

Renal water fluoride residues are transmitted directly into the patient's blood which can cause acute poisoning and damage to the nerve center.

According to Environmental Health Perspectives, fluorine (fluoride ) is an important ingredient that people receive daily from food, tap water, and toothpaste. This substance has a bleaching effect but also adversely affects bones and teeth after long-term use.

Scientific studies show that low levels of fluorine in saliva can protect tooth enamel, demineralize and prevent tooth decay. Today, fluorine is added to most types of toothpaste and oral hygiene products. However, experts recommend that overuse of excess fluorine, in particular over 2mg / l, will darken teeth, often using water with higher fluorine content than 4mg / l can cause bone breakage.

The concentration of fluorine in water exceeds the threshold can cause many consequences for human health.

Previously, the permitted water standard contained fluorine content in the range of 0.7 to 1.5mg / l . However, in 2011, the US Environmental Protection Agency (EPA) tightened this regulation and recommended lowering the total amount of fluorine in water to ensure safety for children.

Many recent studies show that the concentration of fluorine in water exceeds the threshold can cause many consequences for human health. A recent analysis by Harvard University funded by the US National Institutes of Health (NIH) concluded that children living in areas with high concentrations of fluorine water had an IQ lower than Tell ' compared to children who live in areas with lower fluorine concentrations. This conclusion is based on an analysis of the results of the previous 27 surveys. In addition, the study concluded that fluorine affects the brain development of young children stronger than the elderly.

In a 32-page report published on Environmental Health Perspectives, the researchers said that liquid fluorine concentrations absorbed by the body from drinking water could be above 1 mg / L or 50 Smol / L, higher. 1,000 times the concentration of some other neurotoxins. However, exceeding this concentration may cause poisoning.

Experiments on animals also confirmed the effects of fluorine on the nervous system. Specifically, testing on mice exposed to 1 ppm (50 Smol / L) liquid fluorine in one year had a change in brain morphology and aluminum concentration in brain tissue was higher than that of other animals.
