Possible emission sources of PAHs in air and water environments were discussed by a comparison between the data sets of emission sources and environmental fields using five isomer ratios. The similarity of a pair of the datasets of different sources or environment fields for each isomer ratio was evaluated by a newly developed modified effect size d, and the mean of those for the five isomer ratios was applied as an index of similarity. From the analysis, diesel emission and/or biomass burning residues were considered to be major emission sources for almost all the datasets of environments. The pollution loading and path to the PAHs loading of coastal sediments in Hiroshima bay area were examined and it was inferred emission sources was consistently assigned by these newly developed indicators of isomer ratios. Diesel and/or biomass burning were considered to be major sources for the west side area of the bay and the biomass burning was considered to be for the east side area. Further, it was evaluated the west side area, which confronts the Hiroshima city downtown area more directly, was more similar to diesel, and the east side area, which is a bit remoted to the urban central was more similar to the biomass burning. This newly developed method would be a promising alternative application of isomer ratio analysis.

通过异构体比率分析空气和水环境中的PAHs排放源-修改后的Cohen的比较。
通过使用五个异构体比率比较排放源和环境领域的数据集，讨论了空气和水环境中PAHs的可能排放源。通过新开发的修正效应量d评估每个异构体比率的不同来源或环境领域的一对数据集的相似性，并将五个异构体比率的那些平均值作为相似性指标。通过分析，柴油排放和/或生物质燃烧残渣被认为是几乎所有环境数据集的主要排放源。研究了广岛湾地区沿海沉积物的污染负荷和通向PAHs的途径，并通过这些新开发的异构体比率指标一致地推断出排放源。柴油和/或生物质燃烧被认为是海湾西侧区域的主要来源，生物质燃烧被认为是东侧区域。此外，对与广岛市市区直接面对的西侧区域进行了评估，该区域与柴油更相似，而距市区中心稍远的东侧区域与生物质燃烧更为相似。这种新开发的方法将是异构体比率分析的有希望的替代应用。距离城市中心有点远，这更类似于生物质燃烧。这种新开发的方法将是异构体比率分析的有希望的替代应用。距离城市中心有点远，这更类似于生物质燃烧。这种新开发的方法将是异构体比率分析的有希望的替代应用。
