Abstract
The aim of this study was to evaluate placental transfer of fluoride (F) in 30 pregnant women at the time of giving birth, who were living in Poznan, Poland, where the F concentration in the drinking water ranges from 0.4 to 0.8 mg/L. F concentrations of maternal and umbilical venous cord blood plasma were determined in samples drawn at delivery. The mean concentration of F in maternal plasma was significantly higher than in venous cord plasma (3.54 vs. 2.89 ?mol/L, respectively), and both values were similar to those previously documented in pregnant women taking prenatal F supplements. The results confirm that F readily passes through the placenta and that prenatal F supplements, still recommended by some authors, are contraindicated in this population.

Elevated serum fluoride levels in perimenopausal women are related to the components of metabolic syndrome.
OBJECTIVE: Increased fluoride levels can lead to numerous complications, including skeletal effects, cardiotoxicity, endocrine dysfunction, neurotoxicity, hepatotoxicity and nephrotoxicity. The aim of this study was to analyze the relationship between serum fluoride levels and MetS or its individual components, and to assess the diagnostic usefulness of fluoride as a factor contributing to

Environmental Fluoride 1977 by Rose & Marier
The Associate Committee on Scientific Criteria for Environmental Quality was established by the National Research Council of Canada in response to a mandate provided by the Federal Government to develop scientific guidelines for defining the quality of the environment. The concern of the NRC Associate Committee is strictly with scientific

Fluoride concentrations in the human placenta and maternal and cord blood
Fluoride concentrations in maternal and cord blood were measured for the first time with a method specific for inorganic fluoride. The concentrations averaged 0.88 ?M in blood from 16 mothers and 0.68 ?M in the cord blood, with a correlation of 0.86. These results are consistent with the hypothesis that

Predictors of Plasma Fluoride Concentrations in Children and Adolescents.
Despite increasing concerns about neurotoxicity of fluoride in children, sources of fluoride exposure apart from municipal water fluoridation are poorly understood. We aimed to describe the associations of demographics, drinking water characteristics, diet, and oral health behaviors with plasma fluoride concentrations in U.S. children. We used data from 3928 6–19-year-olds

Fluoride Exposure Aggravates the Impact of Iodine Deficiency
A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.
