Abstract：Sixteen samples were analyzed in surface seawater at sixteen stations from Liaodong Bay using Gas Chromatography‐Mass Spectrometer (GC‐MS) in May and August of 2014 and the distribution ,com‐position ,pollution level and main sources of PAHs were discussed .There was average PAHs concentra‐tions of 367 .4 ng/L in May and 138 .2 ng/L in August ,with significant seasonal change in PAHs in sur‐face seawater .Low‐molecular weight PAHs had larger percentage than high‐molecular weight PAHs .The high concentration areas of PAHs were usually in the southwest of Liaodong Bay ,the sea area of Jinzhou Bay and Pulandian Bay .The distribution patterns were affected by the oil platforms and petrochemical in‐dustry garden .The PAHs was derived primarily from the mixed sources of petroleum source and combus‐tion source in May ,and petroleum sources were the main sources of PAHs in August .
