Whether silver is harmful to humans depends on the form and extent of exposure.
While metallic silver poses minimal risk to health, exposure to soluble silver compounds can lead to several adverse effects.
Potential Harmful Effects of Silver Compounds
According to available research, silver in certain forms can be harmful. Here's a breakdown:
-
Argyria and Argyrosis: These conditions cause the skin and internal organs to turn a bluish-gray color due to silver accumulation.
-
Organ Damage: Exposure to soluble silver compounds may lead to liver and kidney damage.
-
Irritation: Silver compounds can irritate the eyes, skin, respiratory tract, and intestinal tract.
-
Blood Cell Changes: Silver exposure might affect blood cell composition.
Here's a table summarizing the potential harmful effects:
| Effect | Description | Compound Type |
|---|---|---|
| Argyria/Argyrosis | Bluish-gray discoloration of skin and organs | Silver compounds |
| Liver/Kidney Damage | Impairment of organ function | Soluble silver compounds |
| Irritation | Inflammation of eyes, skin, respiratory, and intestinal tracts | Soluble silver compounds |
| Blood Changes | Alterations in blood cell composition | Soluble silver compounds |
Metallic Silver vs. Silver Compounds
It is important to differentiate between metallic silver and soluble silver compounds.
-
Metallic Silver: Generally considered to pose minimal risk to health.
-
Soluble Silver Compounds: Can be harmful and lead to the health issues mentioned above.
