Additionally,relative enrichment factors had no significant correlation with 1g K_ in both soil profiles,indicating that PAHs behaviors in soil profile were not influenced by their physicochemical characteristics but other factors(such as eluviate and organism disturbing).

另外，水稻种植前后土壤剖面PAHs相对富集系数与1g k_相关性均不明显，表明PAHs自身理化性质对其迁移特征影响较弱，其他作用机制影响较强。

Further analysis on the pyrogenic PAHs of the Huangpu River sediments discovered two major sources of vehicular exhaust and coal combustion, the contributions of which were quantified as 30% and 27%, respectively.

黄浦江流经上海市区，以燃烧源PAHs污染为主，在不同河段具有不同类型的燃烧源，上游河段PAHs污染主要源于草本植物、木材和煤的不完全燃烧，中下游河段PAHs污染主要来源于油类的燃烧。

During remediation experiment, the addition of benzene acid and Tween 80 gave higher CO2 evolution. The result of Microtox assay showed good correlation between aromatic rings of PAHs at low concentration. The Medaka embryo toxicity test had presented that while eggs were exposed to the soil extracts from fluoranthene and pyrene at high concentration (3mg PAHs/g soil), the embryo showed low hatch ratio、bleeding, high abnormal ratio and delayed mature period. The addition of composting materials for remediation study showed strong embryo toxicity to Medaka embryo at all test concentration.

青鱂鱼鱼卵试验部分，受单一与混合PAHs污染土壤之萃取物对青鱂鱼鱼卵孵化影响，当暴露在浓度3 mg PAHs /g soil时，及四环的Fluoranthene与Pyrene之下，皆有高未孵化率、高出血率、高畸形率及孵化天数的延迟现象产生；而在复育实验之土壤萃取物对青鱂鱼鱼卵孵化之影响，以添加酸性界面活性剂与中性界面活性剂实验组其鱼卵之未孵化率皆为零，与Microtox毒性测试结果有良好的关连；加入不同复育添加剂中，则以添加菜肥之实验组，对於青鱂鱼鱼卵孵化之影响为最大。
