家长吸烟对儿童尿中1-羟基芘的影响

The Effect of Parents Smoking on the Urinary Concentration of 1 Hydroxypyrene of Children.

为了解家长吸烟对小学生尿中１－羟基芘的影响，对４个地区小学生的２３４份尿样中的１－羟基芘及其学校所在地空气中的苯并（ａ）芘进行了同步采样分析．结果显示，学生尿中的１－羟基芘浓度与所在学校空气中苯并（ａ）芘的浓度有显著的正相关关系．家长吸烟组学生尿中１－羟基芘浓度均高于家长不吸烟组，但ｔ检验结果差别不显著．根据测定结果的分析。

sing the urinary 1 hydroxypyrene as a biological index,the effect of parents smoking on the content of 1 hydroxypyrene in the pupil's urine was investigated.The 1 hydroxypyrene level in 234 urine specimens of pupils from 4 urban districts was determined,and the ambient air in these districts was synchronously sampled and analyzed for the content of benzo(a)pyrene (BaP).It was found that the content of urinary 1 hydroxypyrene of the pupils is significantly correlated with the ambient concentration of benzo(a)pyrene in the corresponding region where the school is located.For the groups of pupils whose parents smoke the urinary level of 1 hydroxypyrene are always higher than that of the groups with non smoking parents,but the t tests indicate that the difference is not statistically significant due to small populations.
