In the K1-study from Chen Guilan (2021) the effect of a 28 day exposure on the growth of Rare Minnow (Gobiocypris rarus) to tin sulfide was investigated in a semi-static test according to OECD 215. The test solutions were set up as saturated concentrations with nominal concentrations of 1.04 mg/L, 3.31 mg/L, 10.4 mg/L, 33.1 mg/L and 104 mg test item/L After the suspensions were stirred for about 24 h, the test suspensions were filtered with 0.22 μm water phase polyether sulfone (PES) filter membranes, the filtrates of the nominal concentrations of 1.04 mg/L, 3.31 mg/L, 10.4 mg/L, 33.1 mg/L and 104 mg/L saturated solutions were obtained respectively, and about 2000 ml filtrate from each test concentration group were measured as test solutions directly. The test solutions were exchanged on a daily basis. The time-weighted mean measured concentrations of Sn were 17.6 μg/L, 44.3μg/L, 107 μg/L, 145 μg/L and 149 μg/L, respectively.

No mortality was observed in any of the test groups. In none of the test groups adverse effects were observed. The EC10 was greater than the the highest test concentration, i.e. greater 104 mg/L (nominal) or 149 µg Sn/L mean measured).
The results are considered relevant and reliable for the risk assessment.
