XRF testing of wood-look tile samples with varying Lead test results (see videos)

Introduction:

Tamara Rubin is a Federal award winning independent advocate for consumer goods safety and childhood Lead poisoning prevention. She is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009, and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for metallic toxicants (including Lead, Cadmium, Mercury and Arsenic).

The primary concern with Lead in modern tile is the concern for demolition (or cutting). You can read more about that on this link.

2. Dalhte Meadowood Pine Ceramic Tile:
Glazed Surface – 60-second reading

• Lead (Pb): 27 +/- 4 ppm (reading two: 32 ppm)
• Cadmium: non-detect
• Mercury: non-detect
• Bromine: non-detect

• Cobalt (Co): 367 +/- 28 ppm
• Nickel (Ni): 51 +/- 23 ppm
• Copper (Cu): 133 +/- 12 ppm
• Zinc (Zn): 23,300 +/- 200 ppm
• Zirconium (Zr): 8,830 +/- 91 ppm
• Barium (Ba): 801 +/- 19 ppm

3. Wynwood Natural Wood Plank Porcelain Tile:
Glazed Surface – 60-second reading

• Lead (Pb): 45 +/- 4 ppm (reading two: 45 ppm)
• Cadmium: non-detect
• Mercury: non-detect
• Bromine: non-detect
• Chromium (Cr): 870 +/- 109 ppm
• Iron (Fe): 2,776 +/- 71 ppm
• Cobalt (Co): 418 +/- 29 ppm
• Copper (Cu): 70 +/- 11 ppm
• Zinc (Zn): 16,400 +/- 200 ppm
• Zirconium (Zr): 3,870 +/- 40 ppm
• Barium (Ba): 228 +/- 14 ppm

4. Woodville Natural Wood Plank Ceramic Tile:
Glazed Surface – 60-second reading

• Lead (Pb): 217 +/- 8 ppm (reading two: 217 ppm)
• Cadmium: non-detect
• Mercury: non-detect
• Bromine: non-detect
• Chromium (Cr): 1,285 +/- 119 ppm
• Iron (Fe): 2,286 +/- 66 ppm
• Cobalt (Co): 249 +/- 26 ppm
• Copper (Cu): 142 +/- 13 ppm
• Zinc (Zn): 13,800 +/- 1,000 ppm
• Zirconium (Zr): 6,831 +/- 69 ppm
• Barium (Ba): 481 +/- 16 ppm

All tests on each component are repeated multiple times (using a freshly calibrated XRF instrument) to confirm the levels of toxicants found. XRF test results are accurate, replicable and science-based.

Some additional reading that might be of interest:

• The post discussing the testing methodology used on this website
• Post discussing how to send in an item for testing
• Things that you can test at home.
• Things that might be better tested with an XRF instrument.
• Why home test kits don’t really work on most ceramic items (including most tile and dishes.)

Thanks for reading. Thank you for sharing my posts. As always, please let me know if you have any questions and I will do my best to answer them personally as soon as I have a moment (which may not be right away – but I will try!)
