福建中、东部沿海主要养殖贝类体内石油烃含量调查分析

2002～2004年对福建中、东部沿海主要贝类养殖区8种贝类体内石油烃含量调查结果表明，贝类体内石油烃平均含量为10．6mg／kg，基本符合《海洋生物质量》第一类标准(GB18421—2001)，质量状况较好。本文还对不同地区养殖的贝类体内石油烃含量、以及国内外其他海域的贝类体内的石油烃含量进行比较分析；同种贝类在不同贝类养殖区其体内的石油烃含量差异较大，这与其生活习性以及栖息场地环境条件受污染的程度有关。

Investigation of Petroleum Hydrocarbon Concentration in The Shellfishes from The Main Shellfish Culture Areas in The Middle and East of Fujian Coastal Areas

According to the investigation data of shellfish in the middle and east of Fujian coastal areas from 2002-2004, the concentrations of petroleum hydrocarbon in the shellfishes were studied. The result shown that the average concentration of petroleum hydrocarbon is (10.6 )mg/kg which is conformed to the first level of National Marine Biological Quality(GB 18421-2001). We compare the petroleum hydrocarbon concentrations in different culture areas and the concentration levels in domestic and foreign coastal areas. The result shows that there is notable difference in the same species of shellfish from different areas that have different inhabit environments and polluting extend.
