以鲤鱼为实验生物，应用流动式摄取及释放装置，进行了２，６－二硝基甲苯（２，６－ＤＮＴ）的生物浓缩与释放研究。取得了２，６－ＤＮＴ在鲤鱼（全鱼）、肝及肠部的生物浓缩曲线。全鱼的浓缩曲线可以稳态（平台式）曲线描述，但是肝、肠部浓缩曲线均呈峰形。肝部峰快速下降后渐趋稳态，肠部峰下降未得稳态。峰形，肝在先，肠在后。对比２，６－ＤＮＴ在全鱼及肝、肠的生物浓缩曲线，并参照报道（１，２）指出，全鱼摄取曲线上各点所表现的浓度值为各时刻鱼体内各组织摄取化学品总重对全鱼重量的比值。肝、肠部峰形曲线预示了在肝、肠内生物浓缩过程发生了生物转化作用。对全鱼的生物浓缩过程应用单区一级动力学模型，求得ＢＣＦ值与消除速率常数Ｋ１与Ｋ２，由Ｋ１／Ｋ２计算得到的ＢＣＦ值与实测值相符。释放较慢，释放曲线呈双曲线形，半减期为４．８ｈ。
Carp was used as experimental organism to study the bioconcentration and release of 2,6-dinitrotoluene (2,6-DNT) using a flow-type ingestion and release device. The bioconcentration curves of 2,6-DNT in carp (whole fish), liver and intestine were obtained. Concentration curves of whole fish can be described as steady state (plateau) curves, but the liver and intestine concentration curves all show a peak shape. After the rapid decline of the liver peak gradually steady state, the peak decline in the intestine did not steady state. Peak shape, liver first, intestine in the back. Compared with the bioconcentration curve of 2,6-DNT in whole fish, liver and intestine, and referring to the reports (1, 2), the concentration values of the points on the whole fish intake curve are shown as follows: Total weight to total weight of the fish. Liver, intestine peak curve indicates that in the liver, intestinal bioconcentration occurred bioremediation. Applying a single-zone first-order kinetic model to the whole fish bioconcentration process, the BCF values and elimination rate constants K1 and K2 were calculated. The BCF values calculated from K1 / K2 were in accordance with the measured values. Slow release, release curve hyperbolic, half-reduction of 4.8h.
