Thallium in urine

Thallium is a highly poisonous element for humans. It is absorbed rapidly through not only the gastrointestinal tract, but also the membranes of the mucous membranes, the respiratory system and the skin. It is excreted mainly in urine and to a lesser extent with feces, but this occurs quite slowly Determination of thallium in the blood allows rapid diagnosis of poisoning The initial period of poisoning occurs with diarrhea and vomiting, then there is prolonged constipation. Only after several hours or even days, symptoms appear from the nervous, respiratory and cardiovascular systems. After 2 to 4 weeks, the skin becomes dry, there appear characteristic white striations on the nails and there is plaque-like hair loss. Symptoms can persist for up to month, they can begin to regress, or they can cause the death of the the patient.
