Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
toxicity to other aquatic vertebrates
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Remarks:
Detailed data on test conditions and procedures are not provided, but test was performed according to generally accepted standards available at the time and the test is described in sufficiently detail.
Qualifier:

Details on results:
The LC50 values for formalin are expressed as ppm and were recalculated accounting for a 38-percent aqueous solution and a specific gravity of 1.08.
Reported statistics and error estimates:
LC50 values were calculated using the formula suggested by Carpenter (1960)

Description of key information

The test item is acutely harmful to tadpoles of different species.

Additional information

The toxiciity to tadopoles of different species was tested (Helms 1967). The most sensitive species was Rana papiens with an LC50 (72h) = 8.7 mg/L. The data are not required under REACh and therefore not used for further assessment. Nevertheless the effect values are within the same range as for other aqutic species and are not lower than the most sensitive species (Daphnia magna NOEC(21 d) = 1.04 mg/L)
