Abstract
The risk of ischemic heart disease (IHD) has been studied in relation to working conditions encountered in a primary aluminum smelter employing over 6,000 men. During the period 1975-1983, 306 new cases of IHD were identified which were matched with 575 referents. A logistic regression analysis was performed to adjust for differences in smoking habits, high blood pressure, hyperglycemia, hypercholesterolemia, and obesity. Results from this showed that white collar workers had a significantly lower risk of IHD (odds ratio 0.47, 95% confidence interval 0.31-0.70). Among blue collar workers, a significantly higher risk was observed for workers in the reduction division of the plant (OR 1.72, CI 1.09-2.97) including, in particular, Soderberg (OR 1.71, CI 1.07-2.72) and prebake (OR 2.26, CI. 1.27-4.02) potroom workers. The risk of IHD did not increase with the length of time worked in these occupations. The search for associations (among blue collar workers) of risk with nine specific contaminants (benzene soluble material, fluoride, total dust, sulfur dioxide, carbon monoxide, thermal stress, noise, physical load, and mental load) proved inconclusive, with no association reaching statistical significance.

Telangiectasia in aluminum workers: a follow up.
The cause of telangiectasia was investigated in aluminum (7429905) workers. Physical examinations, biochemical tests, and hemodynamic measurements were performed on 50 current workers, 23 cases of telangiectasia, and 27 comparisons to determine the presence of metabolic disorders. Data was obtained by a self administered questionnaire and by physical examination. Medical

Effects of smoking, use of aluminum utensils, and tamarind consumption on fluorosis in a fluorotic village of Andhra Pradesh, India
A field study was undertaken to determine effects of tamarind, the use of aluminium (Al) cooking utensils, and smoking on dental and skeletal fluorosis in the randomly selected fluoride (F) endemic village of Buttlapally in the Nalgonda District, Andhra Pradesh, India, where the F level in the drinking water is

Protective effect of quercetin against sodium fluoride induced oxidative stress in rat's heart
The antioxidative and cardioprotective properties of quercetin were investigated against sodium fluoride (NaF) induced oxidative stress in rat hearts. Experimental rats were divided into five groups. The first group served as the untreated (normal) control. The second group received NaF at a dose of 600 ppm through drinking water for

Alterations in plasma and tissue acetylcholinesterase activity following repeated oral exposure of chlorpyrifos alone and in conjunction with fluoride in Wistar Rats
Concurrent exposures of more than one environmental contaminants are commonly encountered by human beings and animals. This study investigated the effect of chlorpyrifos alone and in conjunction with fluoride on plasma and tissue acetylcholinesterase (AChE) activity in wistar rats. Fluoride at 1 or 10 ppm in drinking water produced significant (P < 0.05)

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

Fluoride & Arterial Calcification
The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

Skeletal Fluorosis & Individual Variability
One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

Fluoride & Electrocardiogram Abnormalities
An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

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
