Biological Monitoring and Its Application in Environmental Monitoring

Biological monitoring has been developed in recent decades,which is an emerging technology applied in the field of environmental monitoring.By using the reaction of biological individual,population and community to environmental pollution,biological monitoring can expound and evaluate the environmental pollution state,provide monitoring data for the environmental quality assessment.Biological monitoring is a significant part of environmental monitoring,with the advantages of high sensitivity,long-term,continuity,low-cost,non-destructive and comprehensive characteristics.It's expected that biological monitoring could achieve the breakthroughs in areas such as the ecosystem environmental monitoring,total amount control,environmental risk assessment,early warning of environmental pollution,emergency monitoring and environmental standards.Based on summary of the related researches at home and abroad,this paper reviewed the principle,categorization,characteristic,methods and application of biological monitoring used in practice.Although in its infancy,biological monitoring will play an important role in promoting the environmental enterprise,and there are broad prospects for development.
