Technical Bulletin No. 0117: Some Biological Factors in Pulp and Paper Mill Pollution
The National Council has for many years supported research designed to determine the facts related to the basic environmental requirements of various aquatic species. While this work was in most instances especially concerned with determining the dissolved oxygen and toxicity effects of pulp and paper mill discharges, much material of general interest to the field of aquatic biology has been uncovered through these efforts. In the attached Technical Bulletin, Dr. Willis M. Van Horn, Chief of the Biology Group of the Institute of Paper Chemistry, reviews the recent findings of the National Council projects and the work of other investigators in this field. Work has been done both in the laboratory and field relating to the reaction of fish to low oxygen levels.
