Abstract
Natural iodine deficiency and ambient air pollution with fluorine compounds were examined for their combined influence on the prevalence and severity of iodine-deficiency disorders. The excess intake of fluorine was shown to increase the incidence of thyroid diseases and to lower anthropometric indices in children. The preventive measures performed to eliminate iodine-deficiency disorders under intensive ambient air pollution with fluorine compounds were found to be insufficiently effective.

Fluoride-induced thyroid cell apoptosis
In addition to causing skeletal and dental fluorosis, fluoride (F) in drinking water may damage other organs including the thyroid. The objective of this study was to explore the toxicity of F on immortalized human normal thyroid cells (Nthy-ori 3-1) exposed to 0, 0.1, 1, and 3 mmol/L of sodium

Absence of effect of fluoride upon the incidence of thyroid enlargements in Wiltshire schoolgirls.
From the survey by Kilpatrick et al. (p. 654, col. 1, Vol. 32) it was possible to classify 696 schoolgirls in 4 groups according to intake of I, which was higher in those taking school lunches than in those not doing so because iodised salt was used for cooking, and

The specific features of the development of iodine deficiencies in children living under environmental pollution with fluorine compounds.
Characteristics of the development of iodine-deficient states in children growing up in conditions of contamination of the surrounding environment with fluoride compounds. It is known that in the presence of insufficient function of the thyroid gland a whole spectrum of pathologic conditions develops known at the present time as “iodine-deficiency diseases.”

Fluoride & Goiter
Goitre (aka goiter) is an enlargement of the thyroid gland that in some cases can produce visible swelling in the neck. The main cause of goitre is iodine deficiency. Goitre can also be caused by other things, including hypothyroidism and substances that cause goitre (goitrogens). Since as far back as the

Mikhailets (1996): Functional state of thyroid under extended exposure to fluorides
Abnormalities in the thyroid function characterized by a decreased iodine absorption function of the thyroid, a low level T3 syndrome, and a slight increase of the TSH level are observed in cases of chronic fluorine intoxication in the industrial workers.

Fluoride Aggravates Thyroid Damage Caused by Excess Iodine Intake
Chinese researchers have found that the combination of excess fluoride with excess iodine caused greater reductions in IQ, or greater increases in goitre than either scenario by itself.

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

The Relationship Between Fluoride Exposure & Goitre in South Africa
As a general rule simple goitre, irrespective of the cause, can be very, or fairly, satisfactorily combated by an adequate increase in man's daily iodine intake, except when the enlargement of the gland is due to the ingestion of excessive amounts of fluorine. The only correct solution to fluorine-induced endemic goitre is the removal of this element from the drinking water.
