Intelligent environmental systems are emerging as one of the most efficient technologies to monitor the effects of contaminants and environmental changes on various species of organisms. As these systems are computer supported, the retrieval of information is very easy and time saving compared to conventional methods involved in biomonitoring. This chapter gives an overall idea of environmental biomonitoring with the inclusion of new advancements in this field. In this chapter the intelligent environmental systems and their importance is given focus with a critical analysis of this new technology in environmental biomonitoring research and analysis. The evolution of intelligent environmental systems from basic lab analysis to incorporation of smart technologies in biomonitoring are discussed. The history of development of intelligent environmental systems shows that environmental biomonitoring is now a highly sophisticated field and has the potential to provide a large volume of information with the aid of modeling and Geographical Information Systems (GIS). As biomonitoring technologies become more and more sophisticated, more studies can be done in the future on plants, animals and human beings without wastage of time and human energy. The chapter mainly targets researchers, students and the people who are interested to know about the new trends in environmental research and development.
