Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
long-term toxicity to aquatic invertebrates
Type of information:
experimental study
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 211 (Daphnia magna Reproduction Test)
GLP compliance:
not specified

not specified
Vehicle:
no
Test organisms (species):

Details on test organisms:
Daphnia magna; age of neonates was less than 24 h
Test type:
semi-static
Water media type:
freshwater
Limit test:
no
Total exposure duration:
21 d
Hardness:
140-160 mg/L (as CaCO3)

20 +/- 1 deg C
pH:
8.5 +/- 0.2
Reference substance (positive control):
not specified
Duration:
21 d
Dose descriptor:
NOEC
Effect conc.:
> 30 mg/L
Nominal / measured:
nominal
Conc. based on:
act. ingr.
Basis for effect:
reproduction
Remarks on result:
other: number of offspring
Duration:
21 d
Dose descriptor:
EC50
Effect conc.:
154 mg/L
Nominal / measured:
nominal
Conc. based on:
act. ingr.
Basis for effect:
reproduction
Remarks on result:
other: number of offspring
Details on results:
The 21-day NOEC for Daphnia magna was >30 mg/L

There was no significant test substance related mortality of parent animals. The average number of offspring produced per day was 43 in the controls, 38 at 30 mg/L, 29 at 100 mg/L and 13 at 300 mg/L which equates to 88%, 67% and 30% of control response, respectively.

Validity criteria fulfilled:
yes
Conclusions:
The 21-day NOEC for Daphnia magna was >30 mg/L

Description of key information

Additional information

The available data for saltwater invertebrates a are limited and to obtaine the value for PNECs for saltwaters is taken account a assesment factor 10 to extrapolate to NOEC following the “Guidance on Information Requirement and Chemical Safety Assessment R.10: Characterisation of dose [concentration]- response for environment”and “Table R.10-5 Assessment factors proposed for deriving PNEC water for saltwater for different data sets”, to account for the possibility that greater taxonomic diversity in the marine environment makes it likely that some marine taxa may be more sensitive than the most sensitive freshwater taxa
