Currently viewing:

Administrative data

Endpoint:
short-term toxicity to fish
Type of information:
(Q)SAR
Adequacy of study:
disregarded due to major methodological deficiencies
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Documentation about the justification is provided in attachment (See Supporting information). The reliability assessment of the prediction is shown in the attached document as well (QPRF). QSAR model reporting format is shown in the QMRF file attached.
