Abstract
Following a previous study on parathyroid hormone determinations in 200 aluminum potroom workers, we conducted a cross-sectional survey of 116 (58%) of these workers for their levels of serum triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulating hormone (TSH), urinary creatinine, and preshift urinary fluoride (F). The mean serum TSH measured by radioimmunoassay was 1.42±1.26 mIU/L. Serum F measured by the ion selective electrode showed a mean urinary F/creatinine ratio of 2.1±1.36 mg F/g of creatinine with 16 percent of workers having levels above 3 mg F/g of urinary creatinine. Serum TSH concentration did not appear to be related to work duration.

[The change of thyroid functlon from the children with fluoride aluminum combined toxicosis in Shuicheng Area of Guizhou].
The levels of serum T3, T4 and TSH were analyzed in the children with fluoride aluminum combined toxicosis in Shuicheng area of Guizhou as compared with the children without fluoride-aluminum combined toxicosis. The results showed that serum T4 content decreased in the children with fluoride aluminum combined toxicosis (103.9±15.9 nmol/L

Effects of smoking, use of aluminum utensils, and tamarind consumption on fluorosis in a fluorotic village of Andhra Pradesh, India
A field study was undertaken to determine effects of tamarind, the use of aluminium (Al) cooking utensils, and smoking on dental and skeletal fluorosis in the randomly selected fluoride (F) endemic village of Buttlapally in the Nalgonda District, Andhra Pradesh, India, where the F level in the drinking water is

Evaluation of kidney injury biomarkers in an adult Mexican population environmentally exposed to fluoride and low arsenic levels.
Highlights Fluoride exposure increased renal injury biomarkers (ALB, Cys-C, KIM-1 and OPN). Fluoride could be considered an environmental kidney toxicant. Exposure to low concentrations of arsenic does not increase kidney injury biomarkers. Co-exposure to low arsenic level does not enhanced renal fluoride toxicity. Fluoride (F) is a toxicant widely distributed

The relationships between thyroid-stimulating hormone and/or dopamine levels in peripheral blood and IQ in children with different urinary iodine concentrations.
Highlights TSH is not related IQ in children with different urinary iodine concentrations. Dopamine in plasma is unrelated to IQ in children with adequate or excessive iodine. Dopamine has positive correlation with intelligence in iodine deficiency group. The interaction between dopamine in plasma and TSH is not related to

Chronic Fluoride Exposure and the Risk of Autism Spectrum Disorder.
The continuous rise of autism spectrum disorder (ASD) prevalent in the past few decades is causing an increase in public health and socioeconomic concern. A consensus suggests the involvement of both genetic and environmental factors in the ASD etiopathogenesis. Fluoride (F) is rarely recognized among the environmental risk factors of

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.

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

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

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
