根据脂肪烃、多卤联苯、卤代苯和稠环芳烃等80种非极性有机化合物在鱼体中生物富集因子（BCF）的实测数据，建立了有机物在鱼体中生物富集因子的片段常数法估算模型。
Relationship between bioconcentration factor and fragment constants was investigated. A prediction model was developed on the basis of the observed BCF values of 80 non-polar organic compounds.
溶剂对1-溴代烷烃的选择性也产生显著的影响，非极性溶剂有利于1-溴代烷烃选择性的提高；
The solution type also had significant effect on the selectivity of 1-bromo-hydrocarbon, the no polar solution was favorable for the selectivity.
