The acute toxicity of yellow phosphorus (P4) to Atlantic cod (Gadus morhua) and Atlantic salmon smolts (Salmo salar) was investigated using two experimental procedures: (a) continuous exposure and (b) single brief exposure.In continuous-exposure experiments, P4 was lethal to cod and seawater-maintained salmon at concentrations as low as 1.89 and 0.79 μg/liter, respectively. Salmon that were exposed to P4 concentrations of 40 μg/liter or less developed a distinct external red color and showed signs of extensive hemolysis. At death, salmon that had been exposed to P4 concentrations of 90 μg/liter and lower showed a progressive decline in hematocrits. In contrast, cod were never observed to show any evidence of external redness, hemolysis, or reduced hematocrits.In the brief-exposure experiments, cod and salmon were subjected (20 min to 3.5 hr) to P4 concentrations ranging from 245 to 4030 μg/liter. These brief exposures resulted in mortalities to both species that were delayed for as long as 2 weeks. Salmon turned "red" 16–24 hr following exposure, and at death showed evidence of hemolysis and reduced hematocrits. None of the cod exhibited any of these symptoms.
