Description of key information

The lethal concentration (LC50) value of 3-amino-4-hydroxybenzenesulphonic acid in fish (Cyprinodon variegatus) in a 96 hr study on mortality effect was estimated to be 242.211mg/L.Thus,considering the CLP Criteria for aquatic classification of the substance , it is concluded that 3-amino-4-hydroxybenzenesulphonic acid does not exhibit short term toxicity to fish [Cyprinodon variegatus].

Key value for chemical safety assessment

Fresh water fish

Effect concentration:: 242.211 mg/L

Additional information

The lethal concentration (LC50) value of 3-amino-4-hydroxybenzenesulphonic acid in fish (Cyprinodon variegatus) in a 96 hr study on mortality effect was estimated to be 242.211mg/L.Other weight of evidence studies also predicted an LC50 value in range 133.3402mg/l to4464.506 mg/l.

Sr. No	Endpoint name	Value	Units	Species
1	LC50	242.211	mg/l	Cyprinodon variegatus
2	LC50	215.5365	mg/l	Lepomis macrochirus
3	LC50	133.3402	mg/l	Oncorhynchus mykiss
4	LC50	4464.506	mg/l	Fish

Thus considering the value as per the CLP Criteria for aquatic classification of the substance , it is concluded 3-amino-4-hydroxybenzenesulphonic acid could not exhibit short term toxicity to fish.
