Abstract:Jieshi Bay surface seawaterwas sampled twice in May and September 2012 with its oil fingerprint parameters and the monthly difference of these parameters studied.The results showed thatn-alkanes took a unimodal distribution pattern in May with a carbon peak of n-C16 while n-alkanes took a bimodal pattern of distributionin September with two carbon peaks,a significantly higher one and a low-erone;and the surface sea water was affected by oil in May while the sea water was influenced by oil pollution and higher plants in September.For steranes and terpanes in the surface seawater of Jieshi Bay in May and September,the main composition were17α(H) and21β(H)-hopance (C30),followed by 17α(H) and21β(H)-30-norhopane(C29).Theαααof cholestane (C27 sterane) and ethyl cholestane (C29 sterane) were dominant while the content of methyl cholestane (C28sterane) was relatively low.
