关于环境样品中苯并[a]芘(BaP)的测定方法国内外已有不少报导,但对人体尿样中BaP的测定方法报导不多,所见报导多属用有机溶剂萃取来浓缩尿样,既费时间,又费试剂。本文参照了Saxena.J等报导的富集水样中BaP的方法,对尿中BaP的富集进行了研究,试建了测尿中BaP的简便方法,可以用于评价环境中BaP污染或吸烟对人体的直接影响。 There have been many reports on the determination of benzo[a]pyrene (BaP) in environmental samples at home and abroad. However, there are few reports on the determination of BaP in human urine samples. Most of the reports reported on the use of organic solvents for the extraction of concentrated urine. This is not only time-consuming but also expensive. In this paper, the method of BaP enrichment in water samples reported by Saxena.J et al. was studied. The enrichment of BaP in urine was studied, and a simple method for measuring BaP in urine was established. It can be used to evaluate BaP pollution or smoking in the environment. The direct impact on the human body.
