Silver — is a heavy metal that has been used by humans for centuries in everyday life, medicine, and industry.
Despite its antibacterial properties, silver is not considered an essential element and does not play a role in the biochemical processes of the body. Moreover, the accumulation of silver in human tissues leads to toxic effects and can cause chronic health issues.
Toxicity of Silver and Routes of Exposure
Silver can enter the body through:
- inhalation of dust or vapors in industrial production conditions;
- consumption of water and food contaminated with silver compounds;
- medical devices and preparations containing silver ions;
- cosmetics or supplements with colloidal silver.
The main danger lies in the accumulation of silver in tissues, as it is poorly excreted from the body.
Effects on the Body
Chronic exposure to silver causes a condition known as argyria — a permanent discoloration of the skin, mucous membranes, and the sclera of the eyes to a gray-blue color due to the deposition of silver particles. Although this condition is not always associated with acute intoxication, it indicates a disruption of metabolic processes and the accumulation of a toxic metal.
The main consequences of silver exposure include:
- disruption of liver and kidney function due to toxic load;
- irritation of mucous membranes and respiratory tracts;
- skin and mucous membrane damage upon contact with silver compounds;
- weakened immune system and disruption of trace element metabolism;
- risk of nervous system damage at high concentrations.
Acute and Chronic Intoxication
Acute intoxication may manifest as:
- nausea and vomiting;
- abdominal pain;
- headaches and weakness.
With prolonged exposure to silver, chronic intoxication develops, which is characterized by changes in skin pigmentation, chronic inflammation of mucous membranes, and a general decrease in the body’s adaptive capabilities.
Medical and Biotechnological Use
Despite its toxicity, silver continues to be used in medicine in the form of antiseptics, dressings, and medical instruments due to its antibacterial properties.
However, the use of silver-containing preparations must be strictly controlled and limited to avoid the accumulation of the metal in the body.
Conclusion
Silver — is a heavy metal that has no physiological role in the human body and causes toxic effects when accumulated.
Its use is permissible only for limited medical purposes and under the supervision of specialists.
Consumption of supplements or water with colloidal silver poses a serious health risk and can lead to chronic metabolic disorders.
