The US Centers for Disease Control and Prevention (CDC) in 1991 chose 10 micro g/dL as an initial screening level for lead in children's blood. Current data on health risks and intervention options do not support generally lowering that level, but federal lead poisoning prevention efforts can be improved by revising the follow-up testing schedule for infants aged 1 year or less with blood lead levels of 5 micro g/dL or higher; universal education about lead exposure risks; universal administration of improved, locally validated risk-screening questionnaires; enhanced compliance with targeted screening recommendations and federal health program requirements; and development by regulatory agencies of primary prevention criteria that do not use the CDC's intervention level as a target "safe" lead exposure.
1991年,美国疾病控制与预防中心(CDC)选择10微克/分升作为儿童血液中铅含量的初始筛查水平。目前关于健康风险和干预选项的数据并不普遍支持降低该水平,但通过修订对血铅水平为5微克/分升或更高的1岁及以下婴儿的后续检测时间表;开展关于铅暴露风险的普及教育;普遍发放经过改进且在当地经验证的风险筛查问卷;加强对有针对性的筛查建议和联邦健康计划要求的遵守情况;以及监管机构制定不以CDC干预水平作为目标“安全”铅暴露的一级预防标准,可以改进联邦预防铅中毒的工作。
