1978 Copy of “Holly Hobbie’s Answer Book”
Paperback Child’s Book
Note: The XRF instrument tests down to single-digit ppm accuracy. Items intended for use by children are considered toxic and unsafe for children at 90 ppm lead or higher in the paint or coating or 100 ppm paint or coating in the substrate. A “negative” reading for an XRF (in detecting lead) means that it is below the limit of detection for the instrument (below the single digit ppm range) and well within what is considered safe for children by modern standards.
Here are the XRF readings for this item:
- Lead (Pb): Non-Detect
- Cadmium (Cd): Non-Detect
- Arsenic (As): Non-Detect
- Mercury (Hg): Non-Detect
Vintage books often have lead.
