摘　　要：该文改进并完善适合现场实验条件的生物富集动力学参数测定的静态动力学实验方法 ,同时提出比较完善的生物富集动力学模型。应用该模型实验测定 6种浮游植物对 2 -甲基萘的吸收速率常数 k1,释放速率常数 k2 和生物富集因子 BCF。实验表明 ,6种浮游植物对 2 -甲基萘的 BCF与浮游植物细胞比表面积之间有较好的 log- log相关性 ,进一步验证了浮游植物对有机污染物的生物富集与浮游植物的比表面积之间存在定量关系。The method, proposed by Banerjee, for determining Bioconcentiation Factor (BCF) by only measuring the decrease of hydrophobic organic chemicals (HOCs) in water, was improved. A more accurate and reasonable model for determining BCF was developed. With the improved method, the uptake rate constant k 1,eliminate rate constant k 2 and thereafter,BCF for the bioconcentration of 2-methylnanphthalene by 6 species of phytoplankton were determined by this model. It showed that BCF had a log-log correlation with specific surface area of phytoplankton cells. The conclusion is important to the studies on the relationship between the size of marine organisms and the bioconcentration of HOCs.
