The acute toxicity of copper, zinc and manganese and copper‐zinc and copper‐manganese mixtures were determined for juvenile longfin dace, Agosia chrysogaster in hard water bioassays (mean=218 mg 1 −1 CaCO 3 ). Copper‐zinc was the most lethal toxicant (96‐h L.c. 50 = 0.21 mg 1 −1 copper and 0.28 mg 1 −1 zinc) and exhibited a more than additive toxicity which was in contrast to the additive toxicity of copper‐manganese mixtures (96‐h L.c. 50 = 0.45 mg 1 −1 copper and 64.0 mg 1 −1 manganese). The toxicity of copper (96‐h L.c. 50 = 0.86 mg 1 −1 ) and zinc (96‐h L.c. 50 = 0.79 mg 1 −1 ) to the fish was similar but both were considerably more lethal than manganese (96‐h L.c. 50 = 130 mg 1 −1 ).
