A new tool to quickly identify books that are poisonous to humans has been developed by the University of St Andrews.
Historically, publishers used arsenic mixed with copper to achieve a vivid emerald green colour for book covers. While the risk to the public is “low”, handling arsenic-containing books regularly can lead to health issues including irritation of the eyes, nose and throat along with more serious side-effects. The toxic pigment in the book bindings can flake off, meaning small pieces can easily be inhaled.
