结果表明，粉尘有机提取物及其有机酸、多环芳烃、极性化合物可使微核率和SCE率显著增高，并有一定的剂量-反应关系。
The results showed that the dust organic extraction and its polycyclic aromatic hydrocarbons, organic acids, polar compounds increased micronucleus and SCE frequency significantly with a dose effect.
在过成熟阶段，可溶有机质亦发生了芳核的缩聚反应，使芳烃含量减少，大分子的沥青质含量增多。
Dissolvable aroma-hydrocarbons tend to aggregate at the over-maturity stage, resulting in the reduction of aroma-hydrocarbons and the increase of bitumen.
