Ninety‐six h LC50 values for 1,1,3‐trichloro‐, 1,1,3,3‐tetrachloro‐, pentachloro‐ and hexachloroacetone for juvenile rainbow trout ( Salmo gairdneri ) were 2.3, 11.0, 25.0 and >25 mg/L, respectively. Levels in chlorination‐stage effluents from eight pulp mills sampled across Canada were as follows: trichloro‐, <0.1 to 2.4; tetrachloro‐, 0.4 to 6.9; pentachloro‐, 0.1 to 7.5 and hexachloro‐, <0.1 to 0.6 mg/L. Combined levels ranged from 0.9 to 17.0 mg/L.
