Arsenic and Old Books

We covered Arsenic and wallpaper already, but another source of Arsenic you may come across is in old books. 

Potentially, the green colouration of some of those early books could well be Arsenic based.  Though, more than likely, it is present as "Paris Green", have being applied to prevent insect damage to said books.

The article here will give you some more details.

Containers of Paris Green itself tend to pop up in many places. I have seen more containers of it than I can count, from little tins to gallon pails of the stuff.  Many people whose sheds, basements, barns, etc I have gone through realized this poison was present at all.  "Paris Green" does sound innocuous enough....but the skull and crossbones printed on some of the cans should be warning enough, you'd think.

Anyway, just another little tip to help you stay safe while picking!
