A Critical Investigation of the Bioassay Procedure as Related to the Thermal Pollution.
Abstract
Increasing concern over the biological effects of future thermal discharges to the Chesapeake Bay from nuclear power plants has led to a studies of the associated response of the white perch (Roccus americanus) in a brackish water environment. The basis of these experiments was the bioassay test, index number LD(50), which have shown that for water temperatures ranging between 82F and 97F, the deleterious effects on a white perch being held at any temperature within that range will occur within the first 36 hours of exposure. The tests were conducted in laboratory tanks. The results have shown that LD(50), the parameter usually associated with the standard bioassay procedure, does not completely describe the temperature-related effects observed. Three parameters are given which more completely describe the pattern of mortality.
