苯并(a)芘(BaP)是众所周知的强致癌物。有关测定空气、水以及食物中的BaP的方法已有很多报道。但用来测定生物材料,尤其是人尿中的BaP方法却很少。仅有的几篇报道主要是采用固体吸附剂(XAD-2及聚氨基甲酸乙酯泡沫塑料等)浓缩尿中BaP,用柱色谱或薄层色谱分离,然后用紫外分光光度法或荧光法测定。这些方法的预处理较为复杂,不能适应卫生调查中大量样品的测定。尤其紫外法的灵敏度不高,回收率
Benzo (a) pyrene (BaP) is a well-known strong carcinogen. There are many reports of methods for measuring BaP in air, water and food. However, there are few BaP methods used to determine biomaterials, especially in human urine. Only few reports focused on the concentration of urinary BaP using solid sorbents (XAD-2 and polyurethane foam, etc.) and separation by column or thin-layer chromatography followed by UV spectrophotometry or fluorimetry . The pretreatment of these methods is complicated and can not be adapted to the determination of a large number of samples in health surveys. In particular, the sensitivity of UV method is not high, the recovery rate
