摘要/Abstract

摘要： 为了用气相色谱保留时间(t_R)估算取代苯类化合物在鱼体内的生物富集系数(BCF)，测定了草鱼对氯苯、邻氯甲苯、对二氯苯、间二氯苯、邻二氯苯、硝基苯、对氯苯胺、对硝基氯苯、4-氯联苯9种取代苯类化合物的BCF和不同取代苯化合物在6种不同极性固定相上的t_R，建立了t_R与BCF的一元回归方程及t_R一阶分子连接性指数(¹X^V)与BCF的二元回归估算方程.统计检验表明，两类估算方程在不同固定相上的平均相关系数分别为0.952和0.965，均呈极显著相关(P＜0.01)，可用于估算取代苯类化合物在草鱼体内的BCF，估算结果不受固定相极性的影响.

Abstract: To estimate the bioconcentration factor (BCF) of benzene derivatives in fish by gas chromatography retention time (t_R), this paper measured the BCF of chlorobenzene, o-chloro-toluene, p-dichlorobenzene, m-dichlorobenzene, 1,2-dichlorobenzene, nitrobenzene, p-chloro-aniline, p-chloro-nitrobenzene, and 4-chlorodiphenyl in grass crap, and the t_R of test derivatives on the stationary phases of six kinds polarity. The monodic regression equation (Type I Eq.) of BCF and t_Rand the binary regression equation (Type II Eq.) of BCF, t_R and ¹X^Vwere established, and the statistical test showed that there was a significant correlation between BCF and t_R, and the average correlation coefficients on stationary phases of six kinds polarity were 0.952 and 0.965, respectively. The regression equations could be used to estimate the BCF of the benzene derivatives in grass crap, and the results were not affected by the polarity of stationary phases.
