Short-term toxicity to fish

Link to relevant study record(s)

Reference

Endpoint:

short-term toxicity to fish

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1995

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: meets generally accepted standards and acceptable for assessment

Qualifier:

no guideline available

Principles of method if other than guideline:

The study report contains the limited information on the test conditions because the study has been performed in 1995. However available information is sufficient to conclude on the classification of the substance. Further the test was performed on the vertebrates and use of results from old experimental studies is one of the options to provide information requested by REACH. New experimental studies with vertebrates must only be conducted if there is no adequate existing information.
