A chemical analysis procedure was developed to measure within 1.5 hours compounds responsible for the toxicity of pulp mill effluents to fish. Analytical results for 113 samples of raw and biologically-treated bleached and unbleached kraft, sulphite and groundwood effluents were converted via toxic units into estimates of acute lethal toxicity. Agreement between 96-h median lethal concentrations calculated by this method, and values from bioassays of the effluents using rainbow trout was within 30% for 73% of the samples examined. Biological treatment was highly effective in removing the known toxic compounds at pulp mills on the Willamette River, OR. and the Androscoggin River, NH. and ME., based on estimates of toxicant loadings into and out of the biobasins.
