In October 1991, the Centers for Disease Control issued new recommendations lowering the acceptable blood lead level. This change was based on data indicating that irreversible adverse neurodevelopmental effects occur in children with chronic low-level exposure to lead. The primary source of lead poisoning is still lead-based paint, particularly in older urban housing. Other sources of lead poisoning are also common. Almost all U.S. children are considered at risk of lead poisoning and should be screened for lead poisoning. Parents should be provided with information about potential sources of lead during routine well-child visits. Multidisciplinary efforts should be made to reduce all lead exposure. Oral chelation therapy on an outpatient basis is now available to treat less severe cases of lead poisoning.
1991年10月，疾病控制中心发布了新的建议，降低了可接受的血铅水平。这一变化是基于数据表明，慢性低水平接触铅的儿童会出现不可逆的神经发育不良影响。铅中毒的主要来源仍然是含铅油漆，特别是在老旧的城市住房中。其他铅中毒来源也很常见。几乎所有美国儿童都被认为有铅中毒风险，应该接受铅中毒筛查。在儿童定期健康检查期间，应向家长提供有关潜在铅源的信息。应做出多学科努力以减少所有铅暴露。现在可以在门诊进行口服螯合疗法来治疗不太严重的铅中毒病例。
