THE IMPACT OF OIL POLLUTION ALONG COAST OF EAST CHINA SEA ON TOTAL CONTENT OF PETROLEIUM HYDROCARBON WITHIN MARIN ORGANISMS

The distribution and variation in content of petroleum hydrocarbon within soeme main marine organisms along the coastal waters the East China Sea were analyzed and studied as follows : The total content of petroleum hydrocarbon in fish body was measured form 1.4 μg/kg to 21. 84 μg/kg in dry weight with the average 8.91mg/kg . The total content in bivalvia body was from 13.85 μg/kg to 88.63mg/kg in dry weight with the average 44. 77mg/kg, and the total content in crustacea body was from 9.37mg/kg to 59. 35mg/kgin dry weigh with the average 7. 71mg/kg.The results showed the significant difference in the content of petroleum hydrocarbon within the body of marine organisms between non-polluted ones and polluted ones. The fish bodies sampled in outer sea area contained 3. 41mg/kg of petroleum hydrocarbon in average , whereas those from offshore area, Xihu Harbour at Xiangshan Bay, were 17. 58mg/kg. Based on analyses of the bio-concentration of petroleum hydrocarbon within several main organisms in the investigated area , the highest bio-con centration coefficient reached 794. 3.The oil pollution in the coastal waters of the East China Sea can be mainly caused by waste water with oil discharged from ships and boats. It has been quite serious in some local zones.
