Abstract

In pharmacologic doses, perchlorate inhibits thyroidal iodine uptake and subsequently decreases thyroid hormone production. Although pharmacologic doses may be used in the treatment of hyperthyroidism, recent literature has focussed on the detection of low levels of perchlorate in the environment, groundwater and foodstuffs and their potential adverse effects on human thyroid function. This is of particular concern to the developing foetus and infant, whose normal neurodevelopment depends on adequate iodine intake for the production of thyroid hormones. Further research is needed to clarify the potential health effects of low-level chronic environmental perchlorate exposure. The health impact of environmental perchlorate may be dependent upon adequate iodine intake and should be interpreted in combination with other environmental exposures that are also potential thyroidal endocrine disruptors.

  • In humans, trace quantities of ClO4 competitively inhibit iodine ions from being taken up in the thyroid gland, resulting in disruption of hormone output which eventually can lead to severe disruption of organ systems.

    The Abstract and “Effects of perchlorate on thyroid function” state that perchlorate competitively inhibits iodide uptake into the thyroid, and that pharmacologic doses decrease thyroid hormone production. The claim overextends this to trace quantities and severe organ-system disruption: the Abstract says the effects of low-level exposure need further study, while “Studies of perchlorate exposure in healthy volunteers” reports no change in thyroid function at doses above typical environmental exposure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
