对本市98名(工龄1～33年)汽车司机和153名正常人尿中铅和δ-氨基乙酰丙酸(δ-ALA)含量作了对比分析,其结果为:98名接触四乙铅的汽车司机尿中铅含量为0.1158±0.0072μmol/L,正常人(对照组)尿铅含量为0.1351±0.0087μmol/L,两者之间经统计学处理,无显著性差异,同时亦未见尿铅含量随工龄增长而增高。但汽车司机尿
The urinary levels of lead and δ-aminolevulinic acid (δ-ALA) in 98 drivers (1 to 33 years of age) and 153 normal controls were compared. The results were as follows: Urine lead content was 0.1158 ± 0.0072μmol / L in car drivers, and 0.1351 ± 0.0087μmol / L in normal controls (control group). There was no significant difference between the two groups Lead content increased with the growth of seniority. But car drivers urinate
