The plant-soil subsystem is one of the most important terrestrial ecosystems relating to the health. The movement of organic pollutants in this subsystem is dominated by various micro-ecological proc root-soil interface. These micro-ecological processes are mostly driven by physio-chemical and biological induced by root-soil interactions, such as root exudation of organic anions and protons. In order to safeg sustainable production of safety food and to maintain the environmental quality, it is essential to unders mechanisms of these micro-ecological processes. This paper presents a personal overview on the recent achieve this research field with the aim of provoking further in depth research in the near future.
