What does the transition from white chalk on blackboard to black markers on whiteboard mean?
- marcosdumay 1y agoThat people will have fewer cases of lung cancer.
- chopin 1y agoBut more cases of liver cancer.
- kulahan 1y agoPlain chalk is carcinogenic??
- Doxin 1y agoI'd assume getting roughly anything in your lungs frequently enough is carcinogenic.
- kulahan 1y agoDamn nitrogen.
- marcosdumay 1y agoYou have a point. Now that I went looking, most of the literature focus on silicosis, and there aren't many long-term studies that can tell us if it's carcinogenic or not. It's very likely carcinogenic too, but now I don't know what to expect on the correlation, because it's possible that people die from it before they get the chance of developing a tumor.
