<p>We describe a system for monitoring effluent discharge to determine one or both of a biochemical oxygen demand (BOD) and a toxicity of the discharge. The system comprises: a culture vessel comprising a sealable chamber for culturing a fluid sample and a pressure measurement transducer for measuring a pressure in a headspace of the chamber; and a data processing system to: input pressure data from the pressure measurement transducer; and determine a value for one or both of BOD and toxicity from the change in pressure measured by the pressure transducer.</p> |
