Health Effects
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 Routes
The substance can be absorbed into the body by ingestion.
Oral (L808) ; inhalation (L808) ; dermal (L808)
Toxicity Summary
Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org
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
Redness.
Redness.
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)
Human Toxicity Excerpts
SISTER CHROMATID EXCHANGE - IN VITRO CHROMOSOMAL EFFECT STUDIES, HUMAN: NEGATIVE.
Acetate is the primary breakdown product of ethanol metabolism in the liver. ... Systemically administered acetate has been shown to cause motor impairment, an effect which is blocked by the adenosine receptor blocker, 8-phenyltheophylline. The effects of sodium acetate were investigated using intracellualr recording techniques in rat hippocampal dentate granule cells, and were compared to the actions of ethanol and adenosine individually and in conjunction with 8-phenyltheophylline. Acetate hyperpolarized the membrane of 0.4-0.8 mM. The amplitude and duration of the postspike train after hyperpolarization were increased by acetate when the cell was repolarized to the control resting membrane potential. Comparable results were seen in voltage clamp. Acetate also decreased spike frequency adaptation. The effects of acetate were mimicked by adenosine (50 uM) and ethanol (20 mM). The ethanol effects occluded those produced by acetate. All of the effects of acetate, adenosine and ethanol could be inhibited with prior perfusion of 8-phenyltheophylline (1-10 uM). These data suggest that the actions of the major metabolite of ethanol, acetate, and adenosine may be mediated by adenosine receptor activation.
Non-Human Toxicity Excerpts
TEST CONDITIONS WERE: INJECTION VIA AIR CELL & VIA YOLK; & AT 2 TIMES, PREINCUBATION (0 HR) & 96 HR. AT LEAST 100 EMBRYOS/DOSE LEVEL WERE TREATED. SODIUM ACETATE WAS NONTERATOGENIC.
Sodium acetate was evaluated using the Chernoff/Kavlock in vivo teratology screen procedure. End points analyzed as part of this assay were maternal toxicity and early postnatal growth/viability of offspring. Thirty pregnant CD 1 mice were given 1000 mg/kg/day of sodium acetate by gavage on days 8-12 of gestation and allowed to deliver. Forty vehicle-treated animals were used as controls. Sodium acetate induced no observable adverse effects in the dams or their offspring when compared with controls.
Sodium acetate, tested on rabbit eyes as 0.1 M solution adjusted to pH 7.0 to 7.5 and made 0.46 osmolar with sodium chloride or sucrose, caused no disturbance of the cornea, though applied continuously for 3 hr.

Pharmacodynamics
Sodium is the principal cation of extracellular fluid. It comprises more than 90% of total cations at its normal plasma concentration of approximately 140 mEq/liter. The sodium ion exerts a primary role in controlling total body water and its distribution. Acetate ions acts as hydrogen ion acceptor which is alternative to bicarbonate.
Mechanism of Action
It works as a source of sodium ions especially in cases of hyponatremic patients. Sodium has a primary role in regulating extracellular fluid volume. It controls water distribution, fluid and electrolyte balance and the osmotic pressure of body fluids. Sodium is also involved in nerve conduction, muscle contraction, acid-base balance and cell nutrient uptake.
Metabolism/Metabolites
In liver, sodium acetate is being metabolized into bicarbonate. To form bicarbonate, acetate is slowly hydrolyzed to carbon dioxide and water, which are then converted to bicarbonate by the addition of a hydrogen ion.
THE ACETATE ION IS RAPIDLY & COMPLETELY METABOLIZED BY BODY, & CONSEQUENTLY ADMIN OF SODIUM ACETATE IS EVENTUALLY EQUIVALENT TO GIVING SODIUM BICARBONATE. /SODIUM ACETATE TRIHYDRATE, USP/

Readily metabolized outside the liver.
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)

Applications
DescriptionSodium acetate (CH3COONa) is the sodium salt of acetic acid. It appears as a colorless deliquescent salt with a wide range of applications. In industry, it can be used in textile industry to neutralize sulfuric acid waste streams and as a photoresist upon using aniline dyes. In concrete industry, it can be used as a concrete sealant to mitigate the water damage. In food, it can be used as a seasoning. It can also be used as a buffer solution in lab. In addition, it is also used in heating pads, hand warmers and hot ice. For laboratory use, it can be produced by the reaction between acetate with the sodium carbonate, sodium bicarbonate and sodium hydroxide. In industry, it is prepared from the glacial acetic acid and sodium hydroxide.
OccurrenceAcetic acid or acetates are present in most plant and animal tissues in small, but detectable amounts
UsesUsed as buffers. Acidity regulation (buffering) Sodium acetate mixed with acetic acid forms a pH buffer, which can be used to stabilise the pH of foods in the pH-range from 3 to 6. The table below gives indicative values of the composition needed to give a certain pH. The mixtures below can be diluted at least 10 times with minimum effect on pH, however, the stability decreases.
UsesSodium acetate is a mordant in dyeing. Other applications are in photography, as an additive to food, in purification of glucose, in preservation of meat, in tanning, and as a dehydrating agent. In analytical chemistry it is used to prepare buffer solution. Sodium acetate can be used to preserve processed meats and it is often used in combination with other acid based preservatives like lactates and propionates. The typical inclusion level is 0.2 to 0.5%. Sodium acetate is also used in salad dressings and ready-to-eat meals.
UsesSodium Acetate, Anhydrous is a source of acetic acid obtained as a granular powder. it has a solubility of 1 g in 2 ml of water.
General DescriptionSodium Acetate is reported to inhibit the growth of Listeria monocytogenes.
Preparation methods
PreparationSodium acetate is prepared by reacting sodium hydroxide or sodium carbonate with acetic acid in aqueous solution. The solution is evaporated to obtain hydrated crystals of sodium acetate. NaOH + CH3COOH → CH3COONa + H2O Na2CO3 + CH3COOH → 2CH3COONa + CO2 + H2O
