摘要

摘要: 2001年8月和11月在九龙江口红树林区采集了6种底栖动物,测定了它们体内16种多环芳烃的含量.紫游螺(Neritina [Dostia] violacea)、黑口滨螺(Littoraria melanostoma)、可口革囊星虫(Phascolosoma esculenta)、弹涂鱼(Periophthalmus cantonensis)、查加拟蟹守螺(Cerithideadj adjariensis)、孔虾虎鱼(Trypauchen vagina)对沉积物中多环芳烃的富集系数均小于1.弹涂鱼和黑口滨螺体内多环芳烃的含量有随沉积物中多环芳烃含量的增加而增加的趋势,但它们的富集系数却有随沉积物中多环芳烃含量增加而减少的趋势.弹涂鱼、黑口滨螺、查加拟蟹守螺和可口革囊星虫体内多环芳烃主要由二环多环芳烃组成,紫游螺和孔虾虎鱼体内分别是四环和五环多环芳烃比例最高.

Abstract: Six species of macrofauna were collected in mangrove wet land in the Jiulong Estuary in August and November 2001 and their contents of polycy clic aromatic hydrocarbons were determined.The bioaccu mulation factors of Neritina [Dostia] violacea,Littoraria melanostoma,Phascolosoma esculenta,Periophthalmus cantonensis,Cerithidea djadjariensis and Trypauchenvagina are 0.338,0.201,0.152,0.142,0.103 and 0.025,respectively.All of bioaccumulation factors are less than 1.The contents of PAHs in Periophthalmus cantonensis and Littoraria melanostoma are increasing with PAHS contents increase in sediment.However both of their bioaccumulation factors have a decreasing trend while PAHs contents in sediment are increasing.The main PAHs compositions of Periophthal muscantonensis,Littoraria melanostoma,Cerithidea djadjariensis and Phascolosoma esculenta less biaromatics.The main PAHs compositions of Neritina violacea and Try pauchen vagina are,tetra-aromatics and penta-aromatics,respectively.
