Contaminations in sediments by polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs were investigated at 44 sites in Osaka Bay, Japan. Concentrations of total PAHs and alkylated PAHs were in the range 6.40-7800 ng/g dry weights and 13.7-1700 ng/g dry weights, respectively. The PAH concentrations tended to be higher along the shoreline in the vicinities of big ports, industrialized areas, and densely populated regions such as the cities of Osaka and Kobe. The major sources appeared to be pyrogenic or both pyrogenic and petrogenic at most of the sites. PAH concentrations were remarkably high at a site near Kobe, where the concentrations of dibenzo(a,h)anthracene and benzo(g,h,i)perylene exceeded the effects-range-medium concentration and eight PAHs were above the corresponding effects-range-low concentrations. Those PAHs may have been derived from the great fire associated with the large earthquake in 1995.
在日本大阪湾的 44 个地点调查了多环芳烃 (PAHs) 和烷基化多环芳烃在沉积物中的污染情况。总多环芳烃和烷基化多环芳烃的浓度范围分别为 6.40-7800ng/g 干重和 13.7-1700ng/g 干重。在靠近大港口、工业化地区以及大阪和神户等人口密集地区的海岸线附近，PAH 浓度往往较高。在大多数地点，主要来源似乎是热成因或热成因和石油成因的混合物。在神户附近的一个地点，二苯并(a,h)蒽和苯并(g,h,i)苝的浓度超过了效应范围中值浓度，有 8 种多环芳烃超过了相应的效应范围低值浓度，PAH 浓度非常高。这些多环芳烃可能来自于 1995 年大地震引发的大火。
