Determining the acute toxicity of four test substances and an effluent to Lumpsucker (Cyclopterus lumpus)

To assess the 96 hour fish acute toxicity of 4 test substances plus an effluent both post sampling and after 28 days ageing to determine if biodegradation of any of the components in the effluent reduces any toxicity observed. The test uses a static exposure system with test solutions aerated throughout the study.
