- PREPARATION AND APPLICATION OF TEST SOLUTION (especially for difficult test substances)
- Method:
WAFs (water accommodated fractions) solutions with a nominal concentration of 1.00 mg/L was prepared used by adding 0.0010 g of the test substance to the 1000 mL Elendt M7 test medium in glass aspirator bottles with appropriate size. The mixing aspirator bottle was stoppered and the aqueous test substance mixture was stirred for 24 hrs at room temperature (about 23°C ~ 25°C). The vortex height was set at least 10% of the static liquid depth. At the end of the 24 h, stirring was stopped and the mixture was allowed to settle for 1 h at room temperature. Then the aqueous portion removed through the outlet of the aspirator stirring bottle was the WAFs solutions of the test substance without further filtration to remove the floating undissolved test substance.

- Any observations (e.g. precipitation) that might cause a difference between measured and nominal values:
Tin sulfide is almost insoluble in water (water solubility 0.6 µg/L). The LOD in the present study was 1 µg/L and hence the concentration in the medium filtered for analysis was < LOD. In the medium used for exposure of the daphnids, i.e., prior filtration, a concentration of 265 µg/L was measured. This indicates that some particulate matter must have been present in the medium used for the exposure of the daphnids, This concentration was stable throughout the exposure. Since no adverse effects in the exposed daphnids, it can be concluded that the particulate material ad no adverse effects on teh daphnids.
- Effect concentrations exceeding solubility of substance in test medium: No adverse effects were observed when the daphnids were exposed to medium which contained some undissolved material. - Results with reference substance (positive control):
- - Results with reference substance valid? Yes

- Validity criteria fulfilled:
- yes
- Conclusions:
- Under valid static test conditions the 48 h-EL50 of Tin Sulfide to Daphnia magna is greater than the nominal tested concentration of 100 mg/L WAFs (measured concentration 0.265 mg/L) and greater than the water solubility of 0.6 µg/L. Hence, tin sulfide has no acute toxicity to daphnids under the tested conditions.
- Executive summary:
The acute toxicity of tin sulfide to Daphnia magna was determined according to OECD 202 (2004). In a range-finding test 5 daphnids per treatment (no replicates) were exposed to nominal concentrations of 1.0, 10.0 and 100 mg test substance/L WAFs. No immobilization was observed. In the limit test 4 replicates with 5 daphnids per replicate each were tested at 100 mg/L WAF. A blank control was set up in parallel. After 48 h-test period all daphnids in control group and treated group were alive and appeared normal . A reference test with K2Cr2O7 under same conditions resulted in a 24h-LC50 of 1.,27 mg/L. All validity criteria were fulfilled. Under valid static test conditions the 48 h -EL50 of tin sulfide to Daphnia magna is greater than the nominal tested concentration of 100 mg/L WAF and greater than the measured concentration of 265 µg/L, which is greater than the water solubility of 0.6 µg/L. Therefore, it can be concluded that tin sulfide has no acute toxicity to Daphnia magna.

Description of key information
In an acute test with Daphnia magna, it was shown that tin sulfide does not cause toxic effects up to the limit of water solubility.
Key value for chemical safety assessment
Additional information
Tin sulfide is highly insoluble in water. Therefore, short-term aquatic toxicity is unlikely to occur. The long-term aquatic toxicity study on Daphnia (Annex IX, section 9.1.5) was performed. Thus, no short-term toxicity testing is required. This is in accordance with the Annex VII 9.1.1 column 2 (the specific rules for adaptation from column 1) of the REACH regulation.
In an acute test with Daphnia magna, it was shown that tin sulfide does not show toxic effects up to the limit of water solubility.
