• Physical Examination: Assessing symptoms and overall health status.
• Laboratory Tests: Blood tests, urine tests, and possibly imaging studies to determine the level of metal in the body and assess organ function.

2. Decontamination

If the exposure is recent, decontamination is critical:

• Skin Decontamination: If the metal is on the skin, thorough washing with soap and water is essential to prevent further absorption.
• Gastrointestinal Decontamination: In cases of ingestion, activated charcoal may be administered if the patient presents within a few hours of ingestion, as it can bind to certain metals and reduce absorption.

3. Chelation Therapy

Chelation therapy is a cornerstone treatment for heavy metal toxicity. This involves the administration of chelating agents that bind to metals in the bloodstream, facilitating their excretion through the kidneys. Common chelating agents include:

• Dimercaprol (BAL): Effective for arsenic and mercury poisoning.
• EDTA (Ethylenediaminetetraacetic acid): Primarily used for lead poisoning.
• DMSA (Dimercaptosuccinic acid): Used for lead, mercury, and arsenic toxicity.

The choice of chelating agent depends on the specific metal involved and the clinical scenario. It is important to monitor renal function and electrolyte levels during treatment, as chelation can affect kidney function and lead to imbalances.

4. Supportive Care

Supportive care is vital in managing symptoms and complications associated with metal toxicity. This may include:

• Hydration: Ensuring adequate fluid intake to support kidney function and facilitate the excretion of metals.
• Symptomatic Treatment: Addressing specific symptoms such as nausea, vomiting, or neurological disturbances.
• Nutritional Support: Providing a balanced diet to support recovery and overall health.

5. Follow-Up and Monitoring

Post-treatment follow-up is essential to ensure that the patient is recovering adequately and to monitor for any long-term effects of the exposure. This may involve:

• Repeat Testing: To assess metal levels and organ function.
