- 0.001 mg/L
Additional information
The key study provided to fulfil the data requirement, Rufli (1988), was conducted to the standardised OECD guideline No. 201. The study lacked details in the reporting in some areas and some deficiencies were present in the performance of the test, such as the test concentrations were not maintained throughout the entire test period. As such the study was assigned a reliability score of 2 in line with the principles of assigning data quality as outlined in Klimisch (1997). The study was considered reliable with restrictions and suitable for assessment. Under the conditions of the test, the ErC50 of the test substance in algae was determined to be greater than the water solubility of the test substance.
Supporting information was available in the review by Lundnergh (2000). The information was presented as a short summary as part of a risk assessment document. The report summarised information from standard test data and a review by Stuer-Lauridsen et al (1998). From the standard test data, no or only slight effects on growth measured as cell density and biomass was recorded after 72 hours of exposure to saturated solutions (equivalent to 1.8 µg Sn/L). The Stuer-Lauridsen et al (1998) review, in the same species reported an EC10 of 0.03 mg/L (as Sn) and a NOEC of 0.006 mg/L. The report contained very limited detail, and the references for the original sources were not available, the report was therefore assigned a reliability score of 4 in accordance with the principles of assessing data quality as described in Klimisch (1997).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
