Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
No data
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Remarks:
No data on GLP. Near guideline study. Reliable with restrictions. Deficiencies : i) only the results (EC0 and EC50) were reported, without underlying data on concentration response; ii) the test duration is not long enough; iii) data on analytical monitoring of 2-methylfuran are lacking.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
The toxicity of the test substance towards Daphnia was assessed over 24h. The EC0 (24h) is 332 mg/L and EC50 (24h) is 888 mg/L.
Executive summary:

The toxicity of the test substance towards Dapnnia after 24h exposure, was assessed. The study was performed similar to a OECD 202. The effect levels for 2 -methylfuran were measured: EC0 (24h) = 332 mg/L and EC50 (24h) = 888 mg/L.
