Additional information
Different experimental studies for the toxicity to microorganisms endpoint were reviewed for the test substance and are summarised below:
The first study of toxicity to microorganisms was carried out. The duration of study was 48 hr performed under static conditions. Tetrahymena piriformis was taken as microorganism. On the basis of toxicity to microorganisms (Tetrahymena pyriformis) the 48 hr EC50 value was determined to be 7.49 mg/l. As per the value of EC50 the test chemical was consider as toxic to microorganisms.
The second study of toxicity to microorganisms was carried out. The duration of test was 30 min and was performed under static conditions. Photobacterium phosphoreum was taken as test organism. On the basis of toxicity to microorganisms (Photobacterium phosphoreum ) the 30 min EC50 value was determined to be 8.9 mg/l. As per the value of EC50 the test chemical was consider as toxic to microorganism.
The third study of toxicity to microorganisms was carried out. The duration of study was 35 hr performed under static conditions. Tetramitus rostratus was taken as microorganism. On the basis of toxicity to microorganisms (Tetramitus rostratus) the 35 hr EC50 value was determined to be > 1 to < 17 mg/l. As per the value of EC50 the test chemical was consider as toxic to microorganisms.
On the basis of above-mentioned information, the test chemical was considered toxic to microorganisms.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
