Chemical Research in Toxicology, 2014
The earth's resources are finite, and it can no longer be considered a source of inexhaustible bounty for the human population. However, this realization has not been able to contain the human desire for rapid industrialization. The collateral to overusing environmental resources is the high-level contamination of undesirable toxic metals, leading to ...

Quarterly Reviews of Biophysics, 1974
Several reviews have been published recently on the toxicity of heavy metals, but few of these have made any reference to the influence of the nutritional state of animals upon their tolerance of heavy metals. Furthermore, the clinical and metabolic changes occurring as a consequence of increased dietary intake of heavy metals are extremely dependent ...

The American Journal of Clinical Nutrition, 1995
Lead, cadmium, and mercury are toxic metals that are not essential for nutrition. However, the toxic effects of these metals may be mediated or enhanced by interactions or deficiencies of nutritionally essential metals. Lead competes with calcium, inhibiting the release of neurotransmitters, and interferes with the regulation of cell metabolism by ...

Metal toxicity and the respiratory tract
European Respiratory Journal, 1990The type of lung disease caused by metal compounds depends on the nature of the offending agent, its physicochemical form, the dose, exposure conditions and host factors. The fumes or gaseous forms of several metals, e.g. cadmium (Cd), manganese (Mn), mercury (Hg), nickel carbonyl (Nl(CO)4, zinc chloride (ZnCl2), vanadium pentoxide (V2O5), may lead to ...

Metal Toxicity and Speciation: A Review
Current Medicinal Chemistry, 2021Background : Essential metal ions play a specific and fundamental role in human metabolism. Their homeostasis is finely tuned, and any concentration imbalance in the form of deficiency or excess could lead to a progressive reduction and failure of normal biological function, to severe physiological and clinical outcomes, may eventually causing death ...

Toxicity of metals to chick embryos
Bulletin of Environmental Contamination and Toxicology, 1976A comparative index to the embryopathic effects of a number of metals which may appear as trace contaminants in avian food sources is given. Chicken eggs (White Plymouth Rock strain) were treated by yolk injection with sodium arsenite, sodium selenate and chloride salts of cadmium, lead, mercury, methyl mercury and zinc immediately prior to incubation.

Biological markers for metal toxicity
Environmental Toxicology and Pharmacology, 2005Exposure assessment is often considered the weakest link in risk assessment. It is important for investigators to continue to utilize the full potential of biomarkers for chemicals whose exposure is of global concern. This review is concerned with the biomarkers of metal toxicity, as the overall exposure to metals encountered occupationally or in the ...

Metals, Toxicity and Oxidative Stress
Current Medicinal Chemistry, 2005Metal-induced toxicity and carcinogenicity, with an emphasis on the generation and role of reactive oxygen and nitrogen species, is reviewed. Metal-mediated formation of free radicals causes various modifications to DNA bases, enhanced lipid peroxidation, and altered calcium and sulfhydryl homeostasis.
