理想的血铅水平应是零,但由于环境污染体内血铅常常并不为零。美国国家疾病控制中心(CDC)1991年将血铅质量浓度≥100μg/L定义为儿童铅中毒(childhood leadpoisoning)。近来开始重视血铅≥100μg/L是一个群体流行病学的概念,而并非临床医学上的诊断标准。2006年我国调整了儿童
The ideal blood lead level should be zero, but blood lead levels in the body are often not zero due to environmental pollution. The National Center for Disease Control (CDC) defined the blood lead concentration ≥ 100 μg / L as childhood lead poisoning in 1991. Recently, attention has been paid to the concept that blood lead> 100μg / L is a group epidemiology, not a clinical diagnostic criterion. In 2006, China adjusted its children
