This Project Report summarises the main findings of the Toxicity-Based Consents Pilot Study project (493), which was a Direct Toxicity Assessment (DTA) National Centre driven programme managed by a project board comprising Environment Agency and the Scotland and Northern Ireland Forum For Environmental Research (SNIFFER) membership. The aim of the project was to finalise the procedure for using direct toxicity assessment as a tool for consenting appropriate effluents. The pilot study involved testing a draft protocol developed in a previous project (R&D Contract 049) in a series of case studies and making amendments, as necessary, to provide a robust and thoroughly tested procedure which could be used nationally. Overall the protocol can be used to assess the acute lethal toxicity of all major industrial discharges and sewage treatment works effluents, although further development and application of rapid tests would greatly enhance the application. Chronic invertebrate and fish methods with sub-lethal endpoints are being developed to include in the protocol. This will allow these more subtle, but potentially more damaging, effects to be evaluated.
