Effects of exposure to lead during 6-9 months are investigated in 33 workers. They are divided into groups of 21 exposed workers (greater than 2.88 mumol/l PbB) and 12 exposed workers (1.92-2.88 mumol/l PbB). 14 workers were tested as references. We observed significant differences of some sensomotor and mental function between exposed and nonexposed workers. Errors in choice-reaction are correlated with increased levels of the lead exposure (delta-ALA-U, PbB). It is remarkably having established differences between the groups investigated and the correlations already after a duration of exposure shorter than one year. After 18 months without exposure to lead in 11 workers we found tendencies of improving of the results in testing psychic functions.
对33名工人在6至9个月期间接触铅的影响进行了调查。他们被分为两组，一组是21名接触铅的工人（血铅水平大于2.88微摩尔/升），另一组是12名接触铅的工人（血铅水平为1.92 - 2.88微摩尔/升）。14名工人作为对照进行测试。我们观察到接触铅和未接触铅的工人在一些感觉运动和心理功能方面存在显著差异。选择反应错误与铅暴露水平升高（δ-氨基乙酰丙酸-尿，血铅）相关。在接触铅时间短于一年后，已在所研究的组之间发现了显著差异和相关性。11名工人在停止接触铅18个月后，我们发现心理功能测试结果有改善的趋势。
