Additional information
Hooftman RN and De Wolf JM (2003/2004) was the key study for fulfilment of the data requirement. The study was performed in compliance with GLP and to current internationally accepted guidelines (OECD 202 and EU Method C.2). The study was assigned a reliability score of 2 (reliable with restrictions) as there were unavoidable deficiencies present in the study in relation to the analytical methods employed in the study, however due to the physical properties of the substance, derivatisation is the most appropriate method available. The study was a static acute toxicity test with the crustacean species Daphnia Magna (TNO study number: 01-2495/02) the test material was found to have a 48h EC50 value of 0.843 mg.l-1. Correspondingly the No Observed Effect Concentration was 0.44 mg.l-1. A study was performed to assess the acute toxicity of the test material to Daphnia magna.The method followed that described in the OECD Guidelines for Testing of Chemicals (April 2004) No 202," Daphnia sp, Acute Immobilisation Test" referenced as Method C.2 of Commission Regulation (EC) No 440/2008.
Thom RM et al (1991) and Vighi M & Calamari D (1985) were provided as supporting studies and were assigned reliability scores of 3 and 4 respectively.
Thom RM et al (1991), In a Static acute 48-hour toxicity test of dibutyltin dichloride (DBT) to oyster larvae (BNW project number: 12716,) performed to the guideline EPA OPP 72-3 (Estuarine/Marine Fish, Mollusk, or Shrimp Acute Toxicity Test), the test material was determined to have an LC50 of 66.9µg/L and an EC50 of 55.5µg/L. The study was assigned a reliability score of 3 (not reliable) as the methodology contained deficiencies which were considered to have an impact on the accuracy of the test.
Vighi M & Calamari D (1985) was performed according to OECD 202 (and EU Method C.2), however the reporting of the study was insufficient for accurate assessment of the quality of the data, the study was therefore assigned a reliability score of 4 (not assignable). The study was a static acute toxicity test with the crustacean species Daphnia Magna. The test material was found to have an EC50 of 0.9 mg/l.
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).
