Administrative data

Endpoint:
short-term toxicity to fish
Type of information:
other: read-across from supporting substance (structural analogue or surrogate)
Remarks:
the tested substance is one of the two components of the substance under registration.
Adequacy of study:
weight of evidence
Reliability:
