Technical Bulletin No. 0755: Effects of Biologically Treated Unbleached Kraft Pulp Mill Effluent on Early Stages and Life Cycles of Fathead Minnow and Ceriodaphnia dubia

Fathead minnow (Pimephales promelas) 7-d, 28-d, 56-d, and life-cycle bioassays, as well as several biomarker responses, and Ceriodaphnia dubia 7-d bioassays were completed using effluent from a mill producing unbleached kraft market pulp. The mill used approximately 45 m3 of water/ADMT to produce 1450 ADMT of pulp/d from pines. C.
