The toxicity of the test substance to the
freshwater fish BlueGill (Lepomis macrochirus) was investigated using
procedures presented in "Methods for acute toxicity tests with fish,
macroinvertebrates, and amphibians" (U.S. EPA 1975).
Ten fish were randomly selected from a test
population and added to each test jar within 30 min after the addition
of the test chemical. est substance free controls were also maintained
and capped where appropriate. Controls were maintained
under the same conditions as the test solutions. Fish were exposed for a
total of 96 hours. Fish mortality, behavioural and physiological
responses, and solution appearance were observed and recorded at time 0
and every 24 h during exposure.
The 96-hour LC50 of the test substance to
Bluegill (Lepomis macrochirus) was 29 mg/l with 95% confidence limits of
24 -36 mg/L.
Acute toxicity of the test substance to fish.
