Acute oral and ip LD50 values of arsenic trisulfide for mice were 254.3 and 215.1, and for rats 185.0 and 85.8 mg/kg, respectively. The dermal LD50 was 936.0 mg/kg for rats. The threshold of acute toxicity was 0.05 LD50 for rats. A single application to eye caused severe keratoconjuctivitis leading to blindness.

Arsenic is an elusive element, with a mysterious ability to change color, behavior, reactivity, and toxicity. For exam-ple, two arsenic sulfide minerals, red-colored realgar (As 4S 4) and bright yellow orpiment (As 2S 3), were described by the ancient Greeks, but they considered them to be two entirely different substances (Irgolic 1992).
