Description of key information
Low concern for chronic toxicity to aquatic invertebrates of 5-methoxy-2-methylsulphanilic acid based on predicted data and read-across with similar substance.
Key value for chemical safety assessment
Additional information
There are no studies available for chronic toxicity to aquatic invertebrates of 5-methoxy-2-methylsulphanilic acid .
An estimated value of chronic value Daphnid for 5-methoxy-2-methylsulphanilic acid has been calculated by ECOSAR V.1.11 and it is of none concern (ChV Daphnid= 3714.701 mg/l).
To evaluate chronic toxicity to aquatic invertebrates of 5-methoxy-2-methylsulphanilic acid we have analysed the data for compound with similar structure, 4-aminotoluene-3-sulfonic acid. As reported in SIDS Dossier of 4-aminotoluene-3-sulfonic acid approved at SIAM 16 (27 -30 May 2003) with reference to Report No. EAI98002, Environment Agency, Japan (1999): unpublished report NOEC Daphnia magna 21 days for 4-aminotoluene-3-sulfonic acid was 3.2 mg/l. The test was conducted according to OECD TG211.
For justification of read-across see attachment document in section 13.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
