Cadmium (Cd) er et giftig tungmetall uten noen gunstig rolle i menneskekroppen. Langvarig eksponering for cadmium kan forårsake alvorlige helseproblemer, inkludert nyreskader, svekkede bein og økt risiko for kreft. Siden cadmium akkumuleres i kroppen over tid, utgjør selv eksponering på lavt nivå en bekymring for langvarig helse.
Testing for cadmium levels is advisable for individuals with occupational exposure, such as those working in metal smelting, battery manufacturing, or welding. Residents in areas with high industrial pollution or those consuming diets high in cadmium-rich foods (like certain shellfish and organ meats) might also benefit. Smokers are another group at risk, as tobacco contains cadmium.
Cadmium exposure occurs primarily through occupational settings involving cadmium-containing materials. Environmental exposure can arise from contaminated soil and water near industrial areas. Diet is another source, with certain plants and seafood accumulating cadmium. Smoking tobacco significantly increases exposure due to cadmium in tobacco leaves.
Reducing cadmium exposure is the first step in detoxification. This includes using proper safety measures in occupational settings and avoiding tobacco products. A balanced diet can help reduce the absorption of cadmium. In cases of significant poisoning, chelation therapy under supervision might be necessary. Ensuring adequate intake of minerals like zinc, which competes with cadmium for absorption, can also be beneficial. The body’s natural elimination of cadmium is slow, so ongoing monitoring and health support are important.
