|
Objectives: The objective of this study was to identify determine factors for blood VOCs levels in college students.
Methods: Venous blood samples were collected from healthy 29 male and 25 female volunteers. The samples were analyzed with solid-phase microextraction gas chromatography and mass spectrometry.
Results: Blood concentrations of benzene, toluene, ethylbenzene, m-,p-xylene, o-xylene were higher in smoking group than in non-smoking group. Geometric means of smoking group and non-smoking group were 0.45 and 0.36 μg/L in benzene, 0.82 and 0.47 μg/L in toluene, 0.44 and 0.41 μg/L in ethylbenzene, 0.49 and 0.39 μg/L in m-,p-xylene and 0.47 and 0.43 μg/L in o-xylene, respectively. Gender, alcohol drinking, coffee, commuting time (30 minutes) by a car and adjacency between home and road were not associated with increasing blood VOCs concentrations of college students.
Conclusion: Smoking habit was significantly associated with blood concentrations of benzene, toluene, ethylbenzene, o-,m-,p-xylene in college students.
