Water Research, Volume 2, Issue 11, November 1968, Pages 753-760, ISSN 0043-1354, DOI: 10.1016/0043-1354(68)90009-2.
The lethal threshold concentration of neutralized bleached kraft pulp mill effluent for juvenile Atlantic salmon (Salmo salar L.) is about 12-15% in fresh water. This agrees in general with work on other salmonid fish. Larval lobsters (Homarus americanus Milne-Edwards) are reasonably resistant to this waste, and concentrations below 10% did not greatly affect their survival in sea water. Adult lobsters in sea water are more resistant than lobster larvae or salmon parr.
