Re: Some solid information

Hello Johny,

I have spent some time searching the ATSDR and can not find any reference to the 50 times toxicity of NaClO2 with respect to ClO2. Do you happen to have a link?

It's actually closer to 70 times if you average the 2 Sodium Chlorite numbers and divide them into the 10,000 Chlorine Dioxide number.

CHLORINE DIOXIDE AND CHLORITE 25
3. HEALTH EFFECTS
3.2.2 Oral Exposure
3.2.2.1 Death
No information was located regarding death in humans following oral exposure to chlorine dioxide or
chlorite.
Shi and Xie (1999) indicated that an acute oral LD50 value (a dose expected to result in death of 50% of
the dosed animals) for stable chlorine dioxide was >10,000 mg/kg in mice. In rats, acute oral LD50 values
for sodium chlorite (NaClO2) ranged from 105 to 177 mg/kg (equivalent to 79–133 mg chlorite/kg)
(Musil et al. 1964; Seta et al. 1991; Sperling 1959).
