Industries that use fluoride-containing materials are usually aware of their toxicity and adopt adequate medical measures. It has been found that workers in factories who have not been considered as subjected to fluorine hazard and therefore have not been controlled had significantly elevated urinary fluoride levels. Most workers in a medically controlled fertilizer plant had normal urinary levels. Maintenance workers were found to have higher values, up to 12 mg/liter.
[Relationship between fluoride exposure, orthopedic injuries and bone formation markers in patients with coal-burning fluorosis].
Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan
Urinary fluoride as an exposure index in aluminum smelting.
Urinary fluoride was evaluated as an exposure index for a prospective study of asthma in an aluminum smelter. Two studies were conducted to evaluate the relationship between airborne exposure and urinary excretion over a workweek, and to describe exposures among jobs and over time. Thirty-two subjects were evaluated on Days
Association between urine fluoride and dental fluorosis as a toxicity factor in a rural community in the state of San Luis Potosi.
OBJECTIVE: The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico. MATERIALS AND METHODS: A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L) was evaluated. Fluoride exposure
A Benchmark Dose Analysis for Maternal Pregnancy Urine-Fluoride and IQ in Children.
This article is a preprint and has not been peer-reviewed. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice. Abstract As a safe exposure level for fluoride in pregnancy has not been established, we used data from two prospective studies
Prevention of bony fluorosis in aluminum smelter workers. Excretion of fluorides during a seven-day workweek -- Pt. 2.
Abstract 1. The excretion of fluoride is examined among aluminum smelter workers over the course of a seven-day workweek. The data for the first three days of work is best described by the first cycle of a parabolic curve. Each curve is characteristic of the level of exposure associated with specific
