Abstract
We explored the relationship of respiratory symptoms and lung function to exposure to ambient air pollution consisting of particulate and gaseous fluorides. The subjects were 253 North American Indian children 11 to 17 yr of age living on the Akwasasne reserve, which is adjacent to an aluminum smelter. Among boys, closing volume (CV/VC%) was increased in those raised closest to the smelter as opposed to those having lived most of their lives farthest from this source of air pollution. In both sexes, there was a significant linear relationship between increasing CV/VC% and the amount of fluoride contained in a spot urine sample. We conclude that exposure to fluoride air pollution in the community may be associated with abnormalities in small airways. The implication of these abnormalities for future respiratory health is unknown.

Human exposure to hydrogen fluoride induces acute neutrophilic, eicosanoid, and antioxidant changes in nasal lavage fluid
The development of asthma-like symptoms among aluminum potroom workers has been associated with exposure to fluorides. In the present study, the immediate nasal response in humans was examined subsequent to short-term hydrogen fluoride (HF) exposure. Ten healthy subjects were exposed to HF (3.3-3.9 mg/m(3)) for 1 h. Nasal lavage (NAL)

Epistaxis in a low level hydrogen fluoride exposed industrial staff
OBJECTIVES: To assess the effect of exposure to hydrogen fluoride (HF) on the airway mucosa in an industrial setting. METHODS: A cross-sectional study encompassing 33 industrial workers in a flame soldering plant and 44 assembly workers unexposed to HF was performed by means of a questionnaire on symptoms and diagnosis regarding

Health survey of workers of an aluminum plant in China: III. Respiratory symptoms and ventilatory functions.
The respiratory symptoms and ventilatory lung functions of the production-line workers (F-exposed) at an aluminum plant in China have been studied. The data were compared with those obtained from the office workers (controls). F-exposed groups had a higher prevalence of respiratory symptoms than controls and their complaints of phlegm were

Health effects of residential exposure to aluminum plant air pollution
In this study, the authors evaluated the relative risk of residential exposure to air pollution from an aluminum plant. The authors used government-compiled data to compare hospital admissions in 1997 for selected respiratory diseases for 2 communities in Brazil. One community, Ouro Preto, was located near an aluminum plant, and

Occupational asthma in the aluminum smelters of Australia and New Zealand: 1991-2006
OBJECTIVE: To examine the incidence of occupational asthma in the seven aluminum smelters of Australia and New Zealand from 1991 to 2006. METHODS: Incidence and exposure data were collected by survey from the smelters prospectively during the study period. RESULTS: The incidence of occupational asthma across all smelters combined was highest in

Fluoride Enhances Toxicity of Beryllium
Occupational exposure to beryllium is well-documented to put workers' health at risk. The two principal targets of beryllium poisoning are the respiratory system and the skin. Of all beryllium compounds, beryllium fluoride complexes (including beryllium fluoride and beryllium oxyfluoride) appear to be the most toxic. As shown below, studies dating back

Respiratory Risks from Occupational Fluoride Exposure
Starting in the 1930s, scientists have observed that workers exposed to airborne fluorides suffer from an elevated rate of respiratory disorders. For over 50 years, however, US government and industry scientists made repeated assurances that the allowable level of fluoride dusts and gases in industrial workplaces would not cause any
