To evaluate innate effects of the trace elements zirconium, niobium, antimony and vanadium, and to reevaluate those of lead, 603 rats of the Long-Evans strain were fed a diet containing relatively small amounts of these elements in an environment reasonably free of trace contaminants. Groups of 100 or more divided as to sex were given 5 ppm (as metal) either zirconium, niobate, an tÂimoni te, or vanadyl ions, and 25 ppm lead (males only) in drinking water from the time of weaning until natural…

Vanadium, Niobium, and Tantalum

Vanadium (V), niobium (Nb), and tantalum (Ta) are transition metals from group V. They have partly filled d shells, so they are defined as transition elements. Vanadium and niobium are widely

Toxic effects of trace elements on the reproduction of mice and rats.

This method provides fairly rapid estimates of innate toxicities of trace elements in doses tolerable for growth and survival, and in rats, lead was very toxic, and titanium and nickel moderately toxic, resulting in many early deaths and runts.

Zirconium. An abnormal trace element in biology.

The tetravalent nature of the ionic state and the high stability of the compounds formed are important factors that need to be considered, as also the accumulation of this element in the brain, reminiscent of the relationship between Al3+ and Alzheimer's disease.

Arsenic, Antimony, and Bismuth

The production of arsenic usually occurs as a by-product of copper smelting, and is approximately in the range of 50,000–100,000 tons per year but this is a rough estimate based on previous global

Relation of Trace Metals to Human Health Effects

For the past 150 years, civilized man has been exposed more and more widely to metallic contaminants in his environment, resulting from the products of industry. Canning of foods, for example, was

Comparative toxicity and tissue distribution of antimony potassium tartrate in rats and mice dosed by drinking water or intraperitoneal injection.

Rats were more sensitive than mice to the toxic effects of APT, exhibiting dose-related mortality, body weight decrements, and hepatotoxicity, and an ip dose regimen was selected for subsequent studies, indicating that the ip route would be suitable for chronic studies.

Influence of Various Sugars, Chromium and Other Trace Metals on Serum Cholesterol and Glucose of Rats

Because the feeding of brown sugar or chromium(III) to rats had been found to produce lowered serum cholesterol levels for 11 months, studies were continued to 23 months of age to ascertain long-term

Lead levels in tissues from rats fed soils containing lead

The results of this feeding study indicate that these animals metabolize and handle the lead in different soils and from different sources in a very similar manner.

Testicular toxicity evaluation of two antimony compounds, antimony trioxide and antimony potassium tartrate, in rats and mice

It was found that ATO and APT are not toxic to testes in rodents, and neither compound reduced the weights of reproductive organs or accessory sex organs nor affected sperm parameters.



Zirconium, niobium, antimony and fluorine in mice: effects on growth, survival and tissue levels.

Inherent toxicity, manifest by decreased median life spans and longevity and by some suppression of growth of older animals, was observed in females given niobium and antimony, and zirconium occurred in both controls and experimental groups, and showed toxicity.

The Effect of Vanadium Pentoxide, Fluorides, and Tin Compounds on the Dental Caries Experience in Rats

In an attempt to learn the reason for this compound's apparent advantage in effectiveness over sodium fluoride, it was considered of interest to determine whether the form of the tin compound furnishing the stannous ion might contribute significantly to its superiority.
