Abstract: The petroleum hydrocarbon pollution level was evaluated in the south sea area of Zhoushan, according to the investigation result of water, surface sediment and marine animals in Aug.2008 ~Jun.2009, the results showed that in water, the average concentrations of petroleum hydrocarbon accorded with the first and second class of the water of National Standards. The relativity between Petroleum hydrocarbon and pH, salinity, temperature, DO, COD was very small. The concentration of petroleum hydrocarbon in winter was least, other seasons had no evident difference. The quality of surface sediment and marine animals were well.
