Administrative data
Link to relevant study record(s)
- Endpoint:
- toxicity to soil macroorganisms except arthropods: short-term
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 207 (Earthworm, Acute Toxicity Tests)
- Deviations:
- no
- GLP compliance:
- yes
- Test organisms (species):
- Eisenia fetida
- Animal group:
- annelids
- Substrate type:
- artificial soil
- Total exposure duration:
- 14 d
- Nominal and measured concentrations:
- 316, 422 and 563 mg/kg
- Key result
- Duration:
- 14 d
- Dose descriptor:
- LC50
- Effect conc.:
- 472 mg/kg soil dw
- Nominal / measured:
- not specified
- Conc. based on:
- test mat.
- Basis for effect:
- mortality
- Remarks on result:
- other: 95% confidence limits were estimated at 422-563 mg/kg
- Key result
- Duration:
- 14 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 316 mg/kg soil dw
- Nominal / measured:
- not specified
- Conc. based on:
- test mat.
- Basis for effect:
- mortality
- Details on results:
- Mortality of 0, 0, 10% was observed in the control, 316 and 422 mg/kg groups, respectively. 100% mortality occurred at 563 mg/kg and above.
The mean weight change of the surviving worms was not statistically significant at 316 and 422 mglkg. No symptoms of intoxication were
observed in surviving worms at any treatment level after 7 and 14 days exposure. - Validity criteria fulfilled:
- yes
- Conclusions:
- In an OECD 207 study, 1-naphthol had an LC50 of 472 mg/kg soil dw and an NOEC of 316 mg/kg soil dw.
- Executive summary:
In an OECD 207 study, 1-naphthol had an LC50 of 472 mg/kg soil dw and an NOEC of 316 mg/kg soil dw.
