摘　　要：提出用气相色谱相对比保留体积（Ｖｇ（ｒ））估算多环芳烃（ＰＡＨ）在鱼体内的生物浓缩系数（ＢＣＦ）。测定了草鱼对萘、联苯、β－甲基萘、２，３－二甲基萘、２，７－二甲基萘、苊、菲７种ＰＡＨ的ＢＣＦ。建立了在６种不同极性色谱固定相上的ＢＣＦ与Ｖｇ（ｒ）的一元回归方程和ＢＣＦ与Ｖｇ（ｒ）、一阶分子连接性指数（１ Ｘ）的二元回归方程。统计检验表明，两类回归方程总体显著相关，且方程的相关性不受固定相极性的影响。A new method for estimating bioconcentration factor (BCF) of polyaromatic hydrocarbon (naphthalene, biphenyl, β-methyl-naphthalene, 2, 7-dimethyl-naphthalene, 2, 3-dimethyl-naphthalene, acenaphthene and phenanthrene) in grass carp is discussed. The chromatographic parameter of Vg(r), relative specific retention volume, is used to estimate BCF in grass carp. It is not only established the monedic recession equation (Type 1 Eq. ) of BCF and Vg(r) but also the binary regnssion equation (Type 11 Eq. ) of BCF, Vg(r) and 1 X on stationary phases of sir kinds of different polarity. Statistical examination shows that the significant correlation is present for hath regression equations. The correlation of equations is not affected by the polarity of the stationary phases.
