[Advances of studies on ecological risk of herbicide atrazine and its determination and remediation].

With wide application of chemical such as pesticide in farming, the coming problems of ecological risks and environmental pollution were increasingly serious. Residual material of atrazine was founded in the surface water, underground water, and atmospheric sedimentation, and it resulted in the global ecological influences. For atrazine could exit in soil for a long time and enrich in organism, it would bring about potential threaten on the safety of food. The results from experiments on animal indicated that atrazine had biological activity. So, there is an increasing demand for further studying on its ecological risks. In this paper, some viewpoints of the researches on atrazine were introduced. With the development of analytical techniques, the opportunities were created to study on the ecological risks of atrazine, and people should attach serious importance to the bioremediation techniques.
