Test guideline
Qualifier:
according to
Guideline:
other: American Public Health Association 1975
Deviations:
not specified
Principles of method if other than guideline:
American Public Health Association 1975 Bioassays were performed under two different temperatures (22.7oC and 30.8oC) for 72-h in 500 mL beakers for plankton and for 96-h for other animals. Each container held 20 animals and six replicates were used for each test.
