- userbinator 7y agoWorth reading the safety section, which starts with this sentence: Cadmium sulfide is not very toxic (LD50 above 5,000 mg/kg) when used as a pigment, although acute exposure to cadmium vapors from welding is harmful. For comparison, sodium chloride (table salt) has an LD50 of 3,000mg/kg.
- aaronbwebber 7y agoUsing the LD50 for a carcinogen is inappropriate. LD50s are used as a measure of acute toxicity. The issue isn't that it's going to kill you from toxicity, it's that if you expose thousands of children to even low levels of it many more of them will get cancers than they otherwise would.
