[Estimation of bioconcentration factor of benzene derivatives].


PMID 17330488

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(R) and the binary regression equation (Type II Eq.) of BCF, t(R) and 1X(V) were 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.
