Perchlorate Exposure and Thyroid Function in Ammonium Perchlorate Workers in Yicheng, China

Perchlorate Exposure and Thyroid Function in Ammonium Perchlorate Workers in Yicheng, China

The impact of low level dust on the thyroid function of workers chronically exposed to ammonium perchlorate (AP) is uncertain and controversial. The aim of this study was to examine whether workers in China with long-term (>3 years) occupational exposure to low levels of AP dust had affected thyroid homeostasis. Mean occupational exposures to AP dust ranged from 0.43 to 1.17 mg/m3. Geometric me...

Ammonium Perchlorate Disruption of Thyroid Function in Natural Amphibian

We examined indices of thyroid development in tadpoles from ammonium perchlorate (AP)-exposed sites. Bullfrog (Rana catesbeiana) tadpoles collected from a reference site exhibited normal developmental features, with many completing metamorphoses. In contrast, tadpoles collected from the AP contaminated site exhibited a 5-fold lower hindlimb/snout-vent length ratio than tadpoles from the referen...

Commercial interest in perchlorates began in the late 1890s/early 1900s in Europe and the United States as a direct result of the pioneering efforts in rockets and their propulsion systems (Mendiratta et al. 1996). The production of ammonium perchlorate, the largest component of solid rocket propellants, far outpaced that of the other perchlorates listed in Table 4-1. Their commercial manufactu...

Ammonium Perchlorate and Ammonium Perchlorate - Binder Sandwich Combustion

Perchlorate consumption, iodine status, and thyroid function.

Perchlorate inhibits the uptake of iodide into the thyroid gland, thereby possibly affecting the synthesis of thyroid hormones. Pregnant women and their fetuses and newborns have the greatest potential for risk of adverse health effects following exposure to perchlorate. Perchlorate is present in some foods and in drinking water in certain areas of the United States. Based on the available info...
