摘要：Concentrations of benzo[a]pyrene (B[a]P) in ambient air from different areas in Lanzhou city in northwest of China, and its metabolite 1-hydroxypyrene (1-OHP) in the urine of resident children and adults were determined by using gas chromatography/mass spectrometry and high performance liquid chromatography. Results showed that the atmospheric environmental concentration of B[a]P varied significantly from one part of the city to another with levels of 150 ng/m(3) in the industrial area of Xigu and 73.8 ng/m(3) in the agricultural area of Yuzhong. The geometric mean urinary 1-OHP concentration was 0.42 A mu mol/mol-creatinine, with a range of means between 0.067 and 2.05 for the various population sub-groups. The non-occupationally exposed populations' age, gender and area of residence were the major factors that influenced urinary 1-OHP levels. The health risks of B[a]P for adults and children in Xigu and for children in Yuzhong exceeded the acceptable level (1 x 10(-4)) of the US Environmental Protection Agency.
