| 摘 要： | 研究了六种硝基多环芳烃（ＮＯ２－ＰＡＨｓ）在实验室鱼水系统中的归趋，水中ＮＯ２－ＰＡＨｓ的含量在２４ｈ内降低较快；鱼体中积累浓度达最大值的时间各不相同，但在４８ｈ内基本上都达到峰值。测得草鱼对五种ＮＯ２－ＰＡＨｓ的生物浓缩因子在９０－８２０之间，并在生物浓缩因子与正辛醇－水分配系数以及与水溶解度之间建立了线性关系式。

| Abstract: | Grass Carps were exposed to six nitro-PAHs in laboratory aquatic system.The results showed that nitro-PAHs disappeared rapidly at first 24 hours inwaterborne and the equilibrium concentrations in fish were reached within48 hours.The bioconcentration factor(BCF)values at steady-state equilibriumare ranged from 90 to 820 and follow a linear relationship withthe 1-octanol/water partition coefficients and with the aqueous solubilitiesrespectively. |

| Keywords: | fish bioconcentration factor aqueous solubility 1-octano1/water partition coefficient |
