In January--February 1976 blood analyses were performed for two groups (rural and urban) of young girls aged 11--16 years. The following parameters were measured: PbB, ALAD, FEP, haemoglobin and hematocrit. Results indicate only low blood lead levels (PbB less than or equal to 20 microgram/100 ml: ALAD by European method greater than or equal to 33 U/1. A small but statistically significant difference was observed in case of rural/urban ALAD values.
1976年1月至2月，对两组年龄在11至16岁的年轻女孩（农村组和城市组）进行了血液分析。测量了以下参数：血铅（PbB）、δ-氨基乙酰丙酸脱水酶（ALAD）、游离原卟啉（FEP）、血红蛋白和血细胞比容。结果显示血铅水平仅较低（血铅≤20微克/100毫升；采用欧洲方法测定的ALAD≥33 U/1）。农村/城市组的ALAD值存在微小但具有统计学意义的差异。
