Additional information
One acute toxicity study in freshwater fish is available for MAPTAC, which is considered reliable with restrictions (Klimisch score = 2).
In a 48-h acute toxicity study according to DIN 38412 part 15, golden orfes (Idus melanotus HECKEL) were exposed to MAPTAC (50±1% a.i. according to supplier) in nominal concentrations of 2000, 5000 and 10000 mg/L under static conditions.
The 48-h EC50 was > 5000 mg a.i./L. The 48-h NOEC was 5000 mg a.i./L.
The exposure period was only 48 h instead of 96 as recommended for safety assessment. A classification of MAPTAC based only on this study is not possible due to shortened exposure duration.
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.
