In a developmental center, blood lead level was determined by atomic absorption for individuals who were admitted, discharged, or had pica. In 1977, blood lead level was 0 to 29 ug/dL in 298 (92%), 30 to 49 ug/dL in 20 (6%), and 50 to 79 ug/dL in 5 (2%) of the 323 individuals screened. In contrast, in 1994, blood lead level was 0 to 4 ug/dL in 58 (88%) and 5 to 9 ug/dL in 8 (12%) of 66 individuals screened. The observed marked decline in blood lead levels in this population has been the result of effective pica management, several local lead abatement measures, and reduced environmental lead contamination. Medical Practice Guidelines are suggested for prevention of lead poisoning in developmental centers.
在一个发育中心，通过原子吸收法测定了入院、出院或有异食癖的个体的血铅水平。1977年，在接受筛查的323名个体中，血铅水平为0至29微克/分升的有298人（92%），30至49微克/分升的有20人（6%），50至79微克/分升的有5人（2%）。相比之下，1994年，在接受筛查的66名个体中，血铅水平为0至4微克/分升的有58人（88%），5至9微克/分升的有8人（12%）。该人群血铅水平的显著下降是有效管理异食癖、采取多项当地铅减排措施以及减少环境铅污染的结果。建议制定医疗实践指南以预防发育中心的铅中毒。
