| 中文摘要 |
| 本文报告北京市冬季清扫马路工人尿中1-羟基芘的测定结果,并在夏季进行了自身对照测定,29名受试人中有27名是冬季高于夏季.冬季尿中1-羟基芘的几何均值是0.97(μmol/mol肌酐),标准差为0.69;夏季的几何均值是0.14(μmol/mol肌酐)标准差为0.62.t检验证明有非常显著的差别(n=29,t=5.422,p<0.001).讨论了与空气中多环芳烃污染的关系. |
| 英文摘要 |
| Levels of 1-hydroxypyrene in urine were analysed by HPLC for 29 road cleaning workers in Beijing city and 21 herdsmen in Inner-Mongolian grassland where ihe atmosphere is not polluted by industry and coal burning. Mean urinary 1-hydroxypyrene of road cleaning workers was 0.97(μmol/mol creatinine) in winter and 0.14(μmol/ mol creatinine) in summer. The levels of 1-hydroxypyrene in the urine of herdsmen were very similar as compared with those for workers in summer. Statistical treatment shows that there is a very significant difference between the samples collected in witer and in summer (n = 29, t = 5.422. p<0.001). |
