I understand there is a similar problem with old wallpaper in some houses as well. They used Arsenic to get the green shade that people liked in the old days. It's also one reason why it is hard to say if Napoleon died a natural death or not as people had Arsenic in their environment so much back then. Was he poisoned? If so was it accidental or on purpose? We may never know for sure. Arsenic isn't alone either. In the Middle Ages women used powdered lead as make up to make their faces paler. Lead poisoning anyone?
Edit: I see they mention the wallpaper in the article.
