北京地区大气飘尘中检出潜在致癌物——硝基多环芳烃
- DETECTION OF POTENTIAL CARCINOGENSNITRO-SUBSTITUTED POLYNUCLEAR AROMATICHYDROCARBONS (NO2-PAH) IN THE AIRPARTICULATES OF BEIJING AREA
- 摘要:用两种方法(GC-MS法和还原-HPLC-荧光法)首次从北京大气飘尘中检出了数种硝基多环芳烃。虽然它们的含量低,但是由于其中例如1-硝基芘和3-硝基萤蒽系已知的动物致癌物,因此它们在环境中的存在值得注意。
- Abstract:Several nitro-substituted polynuclear aromatic hydrocarbons (NO2-PAH) have been detected in the air particulates from Beijing area by two methods :GC/MS and HPLC-fluorescence after reduction to amino-PAH. Although their concentrations in particulates are not high, their occurrence should call special attention, as the NO2-PAHs detected, e. g. 1-nitropyene and 3-nitrofluoranthene, are known animal carcinogens.
