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:
weight of evidence
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
other: The acute toxicity was tested in accordance with a standardised test system, which did, however, not sufficiently account for the volatility of the test substance. The results are considered as not reliable.

Materials and methods

Principles of method if other than guideline:
The toxicity of the test material to Daphnia magna was assessed in a 24-hour static test in three parallel test series with at least three tested concentrations (details on concentration not provided, dilutions were prepared in the ratio 1:2).
GLP compliance:
no

Test organisms

Test organisms (species):
Daphnia magna
Details on test organisms:
Wild-caught Daphnia were used in the test and the subject with the highest reproduction rate was chosen for the definite test. Animals were held in ap water and fed green algae. Daphnia were held in 2-litre beakers placed on white desks with at least 12 hours daytime (diffuse day light, artificial light if necessary).

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The LC50 value (based on immobility of test animals) for 3-chloropropene determined in a static 24-hour test with Daphnia magna was 250 mg/L.
Executive summary:

The acute toxicity of 3-chloropropene to Daphnia magna was investigated in a standardised 24-hour static test under controlled conditions. The LC50 value (based on immobility of test animals) was 250 mg/L and the LC0 and LC100 values for the same endpoint were 125 and 500 mg/L, respectively.
