Rapid and continuous detection of environmental contaminants in effluents and waterways is important for protecting natural environments and public health, and for managing waster treatment systems. Some novel circulatory system for on line monitoring of dissolved oxygen, pH, humidity and pollutants that make use of fiber optic chemical sensors and biosensors are presented. Some useful approach have been employing chemical and bioluminescent reporter systems that involve whole molecular probes and bioluminescent microbes which provide rapid and visible responses to dissolved oxygen, pH, humidity and the presence of harmful chemicals, including heavy metal ions and petrochemical industry waters. Coupling such chemical and biological detection systems with fiber optic chemical sensors and biosensors for environmental monitoring combines rapid response times, low costs and improved reproducibility.
