Applicant's summary and conclusion
- Executive summary:
National Institute of Technology and Evaluation, Japan (2009).
In 1997 the National Institute of Technology and Evaluation (NITE) of Japan tested the acute toxicity of 1,2,3-Trichlorobenzene to Daphnia magna. The test was conducted according to OECD TG 202 and OECD-GLP standard and is considered to be valid. Unfortunately Japanese Ministry of Environment only published the study result without a detailed study report. The found EC50 after 48 hours was 0.46 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
