北京市不同功能区人体接触多环芳烃的生化指标——人尿中1-羟基芘的水平

A Biochemical Index for Human Exposure to Poly nuclear Aromatic Hydrocarbons (PAHs) --Urinary 1-hydroxypyrene Level of the R-esidents in Different Functional Districts of Beijing.

本文报告北京市不同功能区人尿中1-羟基芘的测定结果,自身对照和群体测定均显示出采暖期与非采暖期的显著差别以及不同功能区样品的差异.尿中1-羟基芘的浓度以焦化厂为最高,为其它各区的4—25倍,依次为工业区、商业区、居民区和对照区,证明用尿中1-羟基芘作为人体接触环境中多环芳烃的一个生物化学指标是可行的.

The paper reports the determination results of urinary 1-hydroxypyrene of the residents who lived in differeat functional districts of Beijing. The data obtained varied in different functional districts, meanwhile those of the residents themselves also varied from heating seasons to non-heating seasons. The results indicates that the level of 1-hydroxypyrene in workers' urine at the coke-oven plant is the highest of all the residents, it is about 4-25 times higher than those who lived in other districts. The order is as follow: industrial district> commercial district> residential district > scenic district. So, it is suggested that 1-hydroxypyrene be a biochemical index for human exposure to PAHs.
