โฆ Synopsis
Biochemical oxygen demand (BOD) is an important index for monitoring organic pollutants in water.
The conventional standard method (5-day BOD test, BOD 5 ), however, is a complicated and time-consuming procedure, including a 5-day incubation, and also requires considerable experience and skill to get reproducible results. To overcome these problems, microbial biosensors allowing the rapid estimation of BOD have been developed. One such BOD sensor system has already been commercialized and another highly sensitive BOD sensor, suitable for use in environmental monitoring in situations where BOD levels are low, is now being investigated. Some examples of these novel BOD sensors are described below.
