Toxicology

Health Effects · 1 item

Silver itself is not toxic to humans, but most silver salts are. In large doses, silver and compounds containing it can be absorbed into the circulatory system and become deposited in various body tissues, leading to argyria, which results in a blue-grayish pigmentation of the skin, eyes, and mucous membranes. Argyria is rare, and although, so far as known, this condition does not otherwise harm a person's health, it is disfiguring and usually permanent. Mild forms of argyria are sometimes mistaken for cyanosis. (L809)

Exposure RoutesOral (L808) ; inhalation (L808) ; dermal (L808)
Toxicity Summary · 1 item

Metallic silver is oxidized and may deposit in the tissues, causing arygria. The silver ion is known to inhibit glutathione peroxidase and NA+,K+-ATPase activity, disrupting selenium-catalyzed sulfhydryl oxidation-reduction reactions and intracellular ion concentrations, respectively. Silver nanoparticles are believed to disrupt the mitochondrial respiratory chain, causing oxidative stress, reduced ATP synthesis, and DNA damage. (L808, A243, A244, A245, A246)

Signs and Symptoms · 1 item

Exposure to high levels of silver for a long period of time may result in a condition called arygria, a blue-gray discoloration of the skin and other body tissues. Argyria is a permanent effect but does not appear to be harmful to health. Exposure to high levels of silver in the air has resulted in breathing problems, lung and throat irritation, and stomach pains. Skin contact with silver can cause mild allergic reactions such as rash, swelling, and inflammation in some people. (L808)

Carcinogen ClassificationNo indication of carcinogenicity to humans (not listed by IARC).

Chemistry & industry

Pharmacology

Metabolism/Metabolites · 1 item

Silver and its compounds can be absorbed via inhalation, while silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in the faeces. (L808)

Silver acetate is commonly used as a pesticide. It also produces a repulsive taste when combined with cigarette smoke, so it is used in chewing gum and lozenges to aid the cessation of smoking. (L813)

Applications · 6 items

DescriptionSilver acetate (C2H3AgO2) is a photosensitive, white, crystalline solid which is widely used in the laboratory. As a source of silver ions lacking an oxidizing anion, it is a useful reagent for direct ortho-arylation, and for conversion of organohalogen compounds into alcohols, etc. It also serves as a catalyst to effectively catalyze the cycloaddition reactions of isocyanoacetates with a variety of olefins. It can be employed in the novel preparation of highly reflective, conductive silvered polymer films.Besides, it has applications in some antismoking drugs and in the health field, in which the products containing silver acetate have been applied in spray, and lozenges to deter smokers from smoking. When mixed with smoke, the silver acetate creates an unpleasant metallic taste in the smoker's mouth, thereby preventing them from smoking.

DescriptionSilver acetate is an organic compound with the empirical formula CH3COOAg (or AgC2H3O2). It is a photosensitive, white crystalline solid. It is a useful reagent in the laboratory as a water soluble source of silver lacking an oxidizing anion. It has been used in some antismoking drugs.

UsesOxidizing agent for use in liquid ammonia: Kline, Kershner, Inorg. Chem. 5, 932 (1966).

UsesIn the health field, silver acetate-containing products have been used in gum, spray, and lozenges to deter smokers from smoking. The silver in these products, when mixed with smoke, creates an unpleasant metallic taste in the smoker's mouth, thus deterring them from smoking. Lozenges containing 2.5 mg of silver acetate showed "modest efficacy" on 500 adult smokers tested over a three-month period. However, over a period of 12 months, prevention failed. In 1974, silver acetate was first introduced in Europe as an over-thecounter smoking-deterrent lozenge (Repaton) and then three years later as a chewing gum (Tabmint).

UsesIt is a reagent in the laboratory as a source of silver ions lacking an oxidizing anion. It is a reagent for direct ortho-arylation, and for conversion of organohalogen compounds into alcohols. Woodward cis-hydroxylation reaction employs silver acetate and iodine for selective conversin of alkenes into cis-diols. Silver acetate is the more preferred reagent for facile carbonylation of primary and secondary amines. It is also employed in the preparation of highly reflective, conductive silvered polymer films.

General DescriptionWhite crystalline plates. Light sensitive. Density 3.26 g / cm3.
