To examine the increase of the polycyclic aromatic hydrocarbons (PAHs) concentrations and natural recovery for the sediment of the Yoro tidal flat, caused by a fire in a neighboring refinery on March 11, 2011, we measured the concentration of eight PAHs containing from three to five rings in the sediment collected between April 2011 and May 2012. After one month from the fire, the PAH concentrations of the sediment samples ranged from 1.4 to 19 μg kg-dry−1 in shallow sediment (0 – 5 mm) and from 2.0 to 31 μg kg-dry−1 in deep regions (10 – 15 cm). The concentrations were about 2 – 5 times as high as those before the outbreak of the fire, and were dominated by phenanthrene, fluoranthene, and pyrene, which were derived from the combustion of propane and butane. The PAH concentrations of the sediment gradually decreased with a lapse of time, and then returned to the same levels as before the fire over about 10 months. This reduction of the PAHs in the sediment is largely attributed to the benthos living in the Yoro tidal flat through their biological activities, such as bioturbation and metabolic activities.
