某些研究发现暴露于汽车废气中的铅可引起血铅(PbB)增高。在过去十年中,许多国家采取了降低铅暴露的措施。瑞典这方面最主要的行动是致力于减低汽油含铅量。本文报道1978～84年瑞典儿童PbB迅速和大幅度降低的情况。作者于1978～84年每年五月末或六月初,在瑞典南部的Landskrona和Trelleborg两城镇(人口各3万多)采集8～16岁学生的静脉血。学生住在上述两城镇内或其邻近乡村,几年中共调查1395名儿童,两地调查儿童的性别和年龄分布相似。 Landskrona离镇中心1 km处有一座废铅
Some studies have found that exposure to lead in car exhaust can cause an increase in blood lead (PbB). In the past decade, many countries have adopted measures to reduce lead exposure. The main move by Sweden in this area is to reduce the lead content of gasoline. This article reports the rapid and drastic reduction of PbB in Swedish children between 1978-84. The authors collected venous blood from 8 to 16 years old in the towns of Landskrona and Trelleborg in southern Sweden (with a population of over 30,000 each) from late May to early June of each year 1978-84. Students live in the above two towns or in the neighboring villages. A total of 1395 children were surveyed in the past few years. The distribution of children in both places is similar in gender and age. Landskrona has a lead scrap at 1 km from the town center
