Coronene is a high molecular weight polycyclic aromatic hydrocarbon with seven aromatic rings. It, more specifically a lower ratio of Benzo[a]pyrene to Coronone (BaP/COR), is suggested as a marker for vehicle emission. In the present study, emissions of Coronene were measured from residential combustions of wood, crop straw, and pellets. The detection of COR in non-vehicle emission sources, and comparable BaP/COR ratios between the solid fuel combustion and vehicle emissions indicated that the generality of COR or the BaP/COR ratio as markers for the vehicle emission would be questionable, especially for the area where solid fuel combustion dominated the PAHs emission.
蔻烯是一种高分子量的多环芳烃，具有七个芳香环。它，更具体地说，是苯并[a]芘与蔻烯的较低比值（BaP/COR），被认为是车辆排放的标志物。在本研究中，从木材、农作物秸秆和颗粒的住宅燃烧中测量了蔻烯的排放。蔻烯在非车辆排放源中的检测，以及固体燃料燃烧和车辆排放之间可比的 BaP/COR 比值表明，COR 或 BaP/COR 比值作为车辆排放标志物的通用性值得怀疑，特别是在固体燃料燃烧主导多环芳烃排放的地区。
