Reference
Endpoint:
short-term toxicity to fish
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1989
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
The information for this endpoint study record was obtained from an experimental study. The OECD GLP criteria were met and the methods were conducted according to laboratory practices commonly used in the year of the execution of the test.
