In 1990, an estimated 3 million children aged < 6 years had blood lead levels (BLLs) > 10 micrograms/dL--levels associated with decreased intellectual performance and other adverse health events. During October 1991, CDC revised its childhood lead poisoning prevention policy statement; the recommendations included lowering the BLL of concern from 25 micrograms/dL to 10 micrograms/dL. To characterize efforts of state health agencies in lead-poisoning prevention and to assess the extent of implementation of the recommendations in the 1991 lead statement, in June 1992, the Lead Task Force of the Association of State and Territorial Health Officials (ASTHO) conducted a questionnaire survey of directors of public health in each of the 50 states. This report summarizes findings of the survey regarding screening issues, funding mechanisms, and follow-up of children with elevated BLLs.
1990年，估计有300万6岁以下儿童的血铅水平（BLLs）超过10微克/分升，这一水平与智力下降及其他不良健康事件相关。1991年10月，美国疾病控制与预防中心（CDC）修订了其儿童铅中毒预防政策声明；建议将关注的血铅水平从25微克/分升降至10微克/分升。为了解各州卫生机构在预防铅中毒方面所做的努力，并评估1991年铅声明中各项建议的实施程度，1992年6月，州和领地卫生官员协会（ASTHO）的铅中毒问题特别工作组对50个州的公共卫生主管进行了问卷调查。本报告总结了该调查在筛查问题、资金机制以及血铅水平升高儿童的随访方面的调查结果。
