Abstract
Exposure of rats to the combined effect of HF and SO2 decreased body weight, O2 consumption and myoglobin levels in muscles and increased the erythrocyte level in blood. Low and high concentrations of HF and SO2 decreased cytochrome oxidase activity in almost all organs and had a toxic effect on succinate dehydrogenase activity in lung, liver and brain tissue. The combined effect of the 2 gases on most indices was of the summation type.

A possible mechanism for combined arsenic and fluoride induced cellular and DNA damage in mice
Arsenic and fluoride are major contaminants of drinking water. Mechanisms of toxicity following individual exposure to arsenic or fluoride are well known. However, it is not explicit how combined exposure to arsenic and fluoride leads to cellular and/or DNA damage. The present study was planned to assess (i) oxidative stress

Oxidative stress parameters in rats exposed to fluoride and caffeine
In our experiment, the 1-month effects of caffeine (Caff) and fluoride (F) administered separately and together on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats were investigated. Also, the influence of caffeine on fluoride excretion with urine was studied. Thirty adult male Wistar rats

[Influence of free radical inducer on the level of oxidative stress in brain of rats with fluorosis].
OBJECTIVE: To study changes in content of lipid peroxide and composition of fatty acids in the brain of rats affiliated with chronic fluorosis after treatment with free radical inducer (ferric ion). METHODS: Thirty-six Wistar rats were divided into three groups, fed with similar fodder and varied concentrations of fluoride in drinking

Challenges of fluoride pollution in environment: Mechanisms and pathological significance of toxicity – A review.
Highlights Fluoride exposure induces mitochondrial function dysfunction. Fluoride exposure mediates organs injury involved in apoptosis and autophagy. Fluoride exposure induces inflammatory reaction. Fluoride exposure results changes in intestinal microbial abundance. Fluoride is an important trace element in the living body. A suitable amount of fluoride has a beneficial effect on

Water treatment with silicofluorides and lead toxicity
Toxic metals like lead, manganese, copper and cadmium damage neurons and deregulate neurotransmitters like serotonin and dopamine (which are essential to normal impulse control and learning). Earlier studies show that - controlling for socio-economic and demographic factors - environmental pollution with lead is a highly significant risk factor in predicting

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride's Effect on Fetal Brain
The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

Fluoride & IQ: 76 Studies
• As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which reported an association of reduced IQ with exposure
