Genetic toxicity in vitro

Description of key information

1,5-Naphthalenedisulfonic acid, disodium salt was investigated in two bacterial gene mutation tetst. The compound was reported to be negative in all tests with all bacterial strains (TA 1535, TA 1537, TA 98, TA 100, and the Escherichia coli strain WP2 uvrA) in the absence or presence of metabolic activation.
