Administrative data

Endpoint:
long-term toxicity to fish
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
other: Iron concentrations of test solutions were above the solubility limit for iron (the study was assessing the effects of suspended iron). - Mechanism of toxicity not investigated. - DOC was not reported.
