Additional information
In 2008, an acute toxicity study of DMDS to Duckweed (Lemna gibba G3) was carried out by Minderhout T, Kendall TZ and Krueger HO according to OECD Guideline 221, EPA OPPTS 850.4400 and GLP requirements. Based on the results of this study, EC 50 - 7d determined, based on frond number, was of 31 mg a.i./L. NOAEC - 7h was of 5.5 mg a.i./L and LOEC was of 12 mg a.i./L. EC 50 - 7h, based on biomass, was of 46 mg a.i./L, EC50 - 7d, based on growth rate and frond number, was of 36 mg a.i./L, and EC50 - 7d, based on growth rate and biomass, was of 75 mg a.i./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.
