Urine lead (Pb)

Urinary lead content is susceptible to environmental pollution, as well as urine volume and renal function. Therefore, the fluctuation is relatively large. Urine lead testing can help diagnose lead poisoning. The average lead load in adults is 121 mg. The digestive tract takes in lead from food and water, and about 10% of it can be absorbed. About 40% of the lead inhaled by the respiratory tract is absorbed. The absorbed lead is distributed in soft tissues such as liver, spleen, kidney, brain, etc. through the blood, and then the lead is redistributed in the body, and 90% is stored in the bone. The lead absorbed into the body is mainly excreted by the kidney, and a small part is excreted by feces, sweat, saliva, and milk. In daily life, excessive lead (>0.5mg/d) is absorbed from the digestive tract (using lead-containing containers, food, drugs) and the respiratory tract (automobile exhaust), which can cause lead poisoning, which is harmful to health, mainly damages the nervous system and Blood system.
