Executive summary:

In a acute oral toxicity study, rat were treated with 2-aminonaphthalene-1,5-disulfonic acid orally. 50% mortality was observedin treated rat at 5430 mg/kg bw. Therefore, LD50 was considered to be 5430 mg/kg bw when rat were treated with2-aminonaphthalene-1,5-disulfonic acid orally.
