Researchers at the University of St Andrews developed a device to quickly identify toxic pigments in books, particularly those containing arsenic for vibrant emerald green covers. While risks are low, repeated exposure can lead to health issues. Historically, testing for these toxins has been costly, prompting libraries to isolate suspect books. The device, deriving from previous technology for mineral detection, leverages unique reflectance patterns to reveal the presence of harmful pigments, streamlining the process for libraries and enhancing public safety.
Handling arsenic-containing books raises health concerns due to flaking toxic pigments that can be inhaled, causing irritation and serious health issues.
A new detection device from the University of St Andrews allows for quick and inexpensive testing of books for toxic emerald green pigment.
The discovery of unique light reflectance patterns from emerald green pigments in the visible spectrum led researchers to develop this portable tool.
Previously, testing for toxic pigments was costly and time-consuming, forcing libraries to isolate thousands of books as a precaution.
