This study was designed to determine current lead exposure in the Barcelona population and to evaluate the changes occurred during the last 10 years. Blood lead concentration was investigated in a random sample of 694 healthy subjects (age range: 0-65 years).
Adults were random selected from a group of blood donors. Samples of children analysed were selected from subjects with a preoperatory analyses without any disease that could modify blood lead levels. Lead levels were determined by atomic absorption spectrometry.
Blood lead concentration was 4.06 +/- 1.4 micrograms/dl in umbilical cord, 8.9 +/- 2.9 micrograms/dl in the paediatric population and 7.8 +/- 4.2 micrograms/dl in the total of adults analyzed. There was statistical differences between the younger subjects and the older population. In 1984 the results found were 18.6 +/- 6.6 micrograms/dl.
The results obtained show that in the last 10 years a reduction on the blood lead levels was occurred. This reduction is parallel with a diminish in the lead petrol concentration in the ambient air.
本研究旨在确定巴塞罗那人群当前的铅暴露情况，并评估过去10年中发生的变化。对694名健康受试者（年龄范围：0 - 65岁）的随机样本进行了血铅浓度调查。
成年人从一组献血者中随机选取。所分析的儿童样本选自术前分析且无任何可能改变血铅水平疾病的受试者。通过原子吸收光谱法测定铅水平。
脐带血铅浓度为4.06±1.4微克/分升，儿科人群为8.9±2.9微克/分升，所分析的成年人群总体为7.8±4.2微克/分升。年轻受试者与老年人群之间存在统计学差异。1984年的结果为18.6±6.6微克/分升。
所获得的结果表明，在过去10年中血铅水平有所下降。这种下降与环境空气中含铅汽油浓度的降低是平行的。
