Physicochemical and hydrodynamic factors of environmental colloids and interface which control the state and migration of chemical substances by means of dissolution, nucleation, micellization, adsorption, diffusion, sedimentation and fluidization are analyzed paying emphasis on the coagulation and flocculation behavior in relation to human activity and natural condition of agro-bio-environment.These activities are closely linked to the international community of Interface against Pollution that plans the Kyoto meeting in 2008. The interrelation has been discussed a series of domestic conferences organized as a line this research activity. In addition to this, the following results are obtained in this year.1) The analysis of zero shear limit rheology of clay suspension by means of special viscometer revealed the role of electrical double layers in the appearance of non-Newtonian behavior.2) Validity of simultaneous analysis of the streaming potential and the stability of colloid in the fate of colloid facilitated transportation was revealed in terms of DLVO theory.3) Dynamic behavior of polyelectrolyte on the surface of colloid was analyzed in relation to flocculation of colloidal particles.

环境胶体和界面的物理化学和流体动力学因素通过溶解，成核，胶束化，吸附，扩散，沉积和流动性来控制化学物质的状态和迁移，从而分析了与人类活动相关的凝结和自然互动的行为，以付费强调与人类活动相关的行为。计划在2008年举行的京都会议的污染。与此研究活动的一系列家庭会议讨论了相互关系。除此之外，还将在今年获得以下结果。1）通过特殊粘土表的零剪切极限流变性的分析揭示了电气双层在非牛顿行为的出现中的作用。2）同时分析流的流传势和胶体式传输的稳定性的流向势和稳定性的collod型行为的稳定性的作用。分析了胶体表面上的聚电解质与胶体颗粒的絮凝相关。
