摘要
据 2 0 0 1年 7、1 0月 2个航次对厦门西港水产养殖海区沉积物中 1 6种优先监测的多环芳烃含量及 3种多环芳烃降解菌的数量进行研究 ,并与厦门西港及其邻近海域非养殖区的进行了比较 .结果表明 :其养殖区沉积物中能检测出的多环芳烃以 4~ 6环的为主 ,并且含量明显高于非养殖区 .在养殖海区的沉积物中检测出的苯并 (b)荧蒽、吲哚芘和苯并 (ghi) 艹北等没有最低安全值的高分子量多环芳烃将直接威胁养殖水质和生物的安全 .3种多环芳烃 (菲、荧蒽、芘 )降解菌数量的最低值都出现在养殖海区 ,而这 3种多环芳烃含量的最高值也均出现在养殖海区 .在非养殖区的 3个站位的沉积物中 ,这 3种多环芳烃的含量与其降解菌数量之间存在着一定的相关性 .作者针对沿岸海域水产养殖区多环芳烃污染的现状与特点 。
The concentrations of 16 kinds of polycyclic aromatic hydrocarbons (PAHs) compounds and 3 species of PAH degrading bacteria in sediments collected from mariculture area and non mariculture area in Western Xiamen Harbor and its adjacent sea area were analysed on summer and autumn cruises in Jul. and Oct. 2001. PAHs in sediments were mainly dominated by high molecular weight PAH compounds (4~6) and the concentration of PAHs in sediments of mariculture area was higher than that of non mariculture area. Some high molecular weight PAH compounds such as benzo(b)fluoranthene, diben(ah)anthracene and benzo(ghi)perylene that their toxicity guidelines was not available were detected. The lowest values of pyrene , fluoranthene and phenanthrene degrading bacteria numbers were found at mariculture area where occurred the highest values of pyrene, fluoranthene and phenanthrene concentration. In non mariculture area, significant positive relationship was found between PAH degrading bacteria and PAHs concentration. The bioremediation strategies in mariculture area were discussed.
