Book excerpt: Rainbow trout were exposed to aluminum at pH 7.25 and 8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO3) for 96 hours in a continuous-flow system and mortality and aluminum accumulation in the gills were determined. Temperature, pH, and dissolved oxygen were measured daily for each treatment. Dissolved and total aluminum concentrations and hardness were determined following exposure periods of 48 and 96 hours. Aluminum was most toxic at pH 8.25, and was more toxic at lower than at higher hardnesses. Water hardness provided a significant protective effect against aluminum-induced mortality (p
