硝基多环芳烃化合物(NO_2-PAH)是近年来在环境中新发现的一类致突变物,曾经在柴油机排出颗粒物、大气飘尘和复印机用墨粉中分离和鉴定出了多种硝基多环芳烃。这类化合物在短期生物试验——Ames试验中显示有直接致突变活性,
Nitro-polycyclic aromatic hydrocarbons (NO 2 -PAH) are newly discovered mutagens in the environment in recent years. Nitro-polycyclic aromatic compounds (NO 2 -PAH) have been isolated and identified in diesel particulate matter, atmospheric fly ash and copier toner. Aromatic hydrocarbons. Such compounds in the short-term biological tests - Ames test showed a direct mutagenic activity,
