Arsenic — is a metalloid that occurs in nature in various forms: from inorganic compounds in water and soil to organic ones — in fish and seafood.
Despite its known toxicity, interest in it remains, as arsenic may influence metabolism and immunity.
Beneficial properties
In minimal amounts, arsenic can participate in metabolic processes and influence the functioning of the immune and nervous systems.
Some studies link its involvement to the synthesis of methionine and the regulation of enzymatic activity.
It is also suggested that arsenic may help maintain metabolic balance; however, there are no clear recommendations for its use in therapy.
Sources of intake
Arsenic can enter the body through food and water.
The World Health Organization limits arsenic content in drinking water to 0.01 mg/L.
Possible sources of intake:
- seafood, especially from contaminated water bodies;
- grains and meat (depending on soil and feed);
- water from natural sources;
- industrial pollutants (through air, pesticides, fertilizers).
Possible risks of excess and their manifestations
Excess arsenic poses a serious danger. It can accumulate in the body, especially with prolonged exposure to contaminated water or air.
Consequences of arsenic poisoning:
- headaches, weakness, nausea;
- skin lesions — hyperkeratosis, darkening, rashes;
- arsenofibrosis and lung damage;
- increased risk of oncology (skin, lungs, bladder);
- depression, anxiety, decreased cognitive functions.
Chronic arsenic poisoning is associated with the risk of cancer, liver and kidney damage, and nervous system disorders.
The safe level of arsenic in the blood — should not exceed 0.1 µg/ml. If exceeded, diagnosis and identification of the source of exposure are necessary.
