研究了台州湾海域海水和表层沉积物中15种多环芳烃(PAHs)的浓度水平,评价了表层沉积物对多环芳烃的富集规律,探讨其可能来源.结果表明,表层沉积物中PAHs的浓度范围为85.4 ～ 167.6 ng/g,平均值为138.62 ng/g,总多环芳烃的最大值是椒江码头.表层沉积物中二环、三环、四环、五环和六环多环芳烃占总多环芳烃的百分含量平均值分别为7.8 %,42.1 %, 33.3 %, 9.6 %和 7.2 %,三环多环芳烃的含量最高;表层沉积物对多环芳烃的富集系数为532.7 ～ 1068.9,平均值为807.5,单组分菲的富集系数最高为122.7,最小的是苯并(a)芘为2.7;台州湾表层沉积物中的多环芳烃主要来源于燃煤污染,部分来源于石油烃类物质的直接污染.
研究瞭檯州灣海域海水和錶層沉積物中15種多環芳烴(PAHs)的濃度水平,評價瞭錶層沉積物對多環芳烴的富集規律,探討其可能來源.結果錶明,錶層沉積物中PAHs的濃度範圍為85.4 ～ 167.6 ng/g,平均值為138.62 ng/g,總多環芳烴的最大值是椒江碼頭.錶層沉積物中二環、三環、四環、五環和六環多環芳烴佔總多環芳烴的百分含量平均值分彆為7.8 %,42.1 %, 33.3 %, 9.6 %和 7.2 %,三環多環芳烴的含量最高;錶層沉積物對多環芳烴的富集繫數為532.7 ～ 1068.9,平均值為807.5,單組分菲的富集繫數最高為122.7,最小的是苯併(a)芘為2.7;檯州灣錶層沉積物中的多環芳烴主要來源于燃煤汙染,部分來源于石油烴類物質的直接汙染.

The concentrations, accumulation and sources of 15 polycyclic aromatic hydrocarbons (PAHs) had been studied or evaluated in the surface layer sediments of Taizhou Bay, China. It showed that the concentrations of PAHs ranged from 85.4 to 167.6 ng/g (averaged 138.62 ng/g), and the highest level was found in Jiao Jiang Dock. Percentages of 2-, 3-, 4-, 5- and 6-cyclic aromatic hydrocarbons were 7.8 %, 42.1 %, 33.3 %, 9.6 % and 7.2 % respectively. The accumulation indices of PAHs ranged from 532.7 to 1068.9 (averaged 807.5), and the index of Phenanthrene was the highest (122.7), while that of Benzo (a) Pyrene was the lowest (2.7) among them. In Taizhou Bay, PAHs in surface layer sediments came mainly from coal burning, partly from direct pollution of petroleum hydrocarbons.
