Abstract

  Automated biomonitors operate on a real-time basis and utilize living organisms as the sensors. Traditionally, chemical monitors have been used to assess water quality. However, biological monitors respond to a greater number of toxic conditions. An overview of the various automated biomonitors, assessed by the types of biological sensors employed, is presented. The sensors used include bacteria, algae, invertebrates, and fish. Of all the systems, those monitoring the ventilatory behavior of fish development, commercial availability, and field testing.
