The Advance of Protozoa as the Model Animal in the Environment

Abstract

With the development of modern industry, the problem of environment pollution becomes more and more serious. It has become an important issue to conduct the environment monitoring rapidly and effective. Fish, alga, higher aquatic plants and benthic macro-invertebrate are always used in the environment monitoring. In recent years, protozoa are widely applied to the monitor of soil environment pollution and water pollution. Protozoa are the most original and the lowest unicellular animals, and they play an important role as the predator and primary consumer in the energy flow and circulation of materials. Protozoa become an ideal model animal in the process of assessing the quality change.
