铅在血液里半周期1个月左右。随时间降低。过期不好测。部分铅排出體外, 部分铅从血进到组织里。大多数沉淀到骨骼, 少数沉淀到软组织如大脑。治疗不可能完全清除。并且治疗本身有一定副作用。最好的办法是预防。知道了血铅高, 除非超高要治疗, 否则也只能避免恶化。铅还会在身体里, 想想儿童几十年时间被铅毒化。见下文

In recent years, research has shown that lower levels of exposure can cause significant cognitive and behavioral problems, including lower intelligence quotient (IQs). As a result, the CDC revised its guidelines in 2021 so that the current level of concern in children is 3.5 mcg/dL.17
Even so, this level of toxicity doesn't mean that chelation therapy is needed. Chelation therapy is typically started at higher blood levels due to limited evidence that the procedure is beneficial at lower blood levels
Is lead poisoning reversible?
Some of the harms caused by lead poisoning are reversible, including kidney and heart problems.1 But, any brain damage caused by lead poisoning is generally not reversible. Chelation therapy may remove lead to the point where it is less likely to cause harm, but it may not remove it completely.
Is lead poisoning treatment safe?
If administered appropriately, chelation therapy is relatively safe, With that said, it is typically avoided in people with kidney failure or heart failure due to the risk of kidney damage or hypocalcemia (a condition that can induce heart failure). The intravenous chelating agent dimercaprol cannot be used in people with a peanut allergy.
What are the long-term effects of lead poisoning?
The long-term consequences of lead poisoning include high blood pressure, heart disease, kidney disease, and lung, stomach, or bladder cancer.1
It can also cause pregnancy complications such as low birth weight, preterm birth, miscarriage, and stillbirth
