To research the environmental contamination of a tidal flat, caused by a fire in a neighboring refinery on March 11, 2011, we measured the concentration of eight polycyclic aromatic hydrocarbons(PAHs) including benzo [a] pyrene in the sediment of the tidal flat and investigated the change in the PAH concentrations with the lapse of time. After a month from the fire, we collected for the sediment and measured the PAH concentrations, which ranged from 1.7 to 28.4 ug/kg-dry. The concentrations were about 3 times as high as those before the outbreak of the fire. After one year from the accident, we repeated the sampling and measurement : the concentrations ranged from 1.0 to 5.1 ug/kg-dry.Therefore it was confirmed that the PAH concentrations in the tidal flat increased once, but then gradually decreased down to a level similar to that before the fire over about a year.

为研究2011年3月11日某炼油厂火灾对滩涂环境的污染，对滩涂沉积物中苯并[a]芘等8种多环芳烃（PAHs）的浓度进行了测定，并分析了PAHs浓度随时间的变化。火灾发生一个月后，我们收集了沉积物并测量了PAH浓度，范围为1.7至28.4 ug/kg-干重。浓度约为火灾发生前的3倍。事故发生一年后，我们重复采样和测量，浓度范围为1.0 - 5.1 ug/kg-dry，因此可以确认，潮滩中的PAH浓度一度升高，但随后在大约一年的时间内逐渐下降至与火灾前相似的水平。
