【摘要】 对上海东部地区非铅作业工，近30个工种的108例，工龄1～4年，男54例，女54例，平均年龄35岁。留取班前尿，采用石墨炉原子吸收测定法进行尿铅本底值测定，尿铅结果呈偏态分布。用百分位数统计处理，中位数为11.18μg/L，95%上限为36μg/L，本方法检出限为1.182±2μg/L，线性范围在0～80ppb。

    【Abstract】 108 non-lead workers from nearly 30 types of work at eastern area of Shanghai have 1 to 4 working years, among which 54 are males and 54 are females. The average age is 35. Take and keep these workers’ urines before they go on duty. According to the determination of the background value of urine lead by graphite furnace-atom absorption method, the result of urine lead presents skewed distribution. The statistics by percentile shows that median is 11.18μg/L, 95% of the upper limit is 36μg/L, detection limit of this method is 1.182±2μg/L and the range of linearity is from 0 to 80ppb.
