本文研究了ALA-D(δ-氨基乙酰丙酸脱水酶)活性能否在接触低浓度铅的普通居民中作为铅吸收的良好定量指标。研究的对象根据接触铅程度的不同,分成三组:第一组,代表“正常”农村居民,从十个家庭中选出30人,每个家庭包括双亲及一个小孩,这些对象住在乡村至少五年,居住环境中没 This article examined whether ALA-D (δ-aminolevulinic acid dehydratase) activity was a good quantitative indicator of lead uptake in the general population exposed to low concentrations of lead. The subjects were divided into three groups according to the level of exposure to lead: Group 1, representing “normal” rural residents, and 30 from ten families, each consisting of parents and a child who lived in the country at least Five years, no living environment
