Executive summary:

Toxic effects of test substance6 amino-1 ,3 naphthalene –disulfonic acid was determined on bacteriafor 24 hrs in static condition and in fresh water.During experiment the effect concentration (EC0) value was1000 mg/l.

 Based on the experimental data the effect concentration (EC0) of test substancesubstance 6 amino-1, 3 naphthalene –disulfonic acid for bacteria was 1000mg/l. And thus the chemical was non toxic and not classified as per the CLP classification criteria.
