#XRFTesting: Monkey Feet Brown Leather Buckle Shoes

Exterior Brown Leather, Top of Shoe:

  • Barium (Ba): 742 +/- 140 ppm
  • Chromium (Cr): 1,604 +/- 113 ppm
  • Zinc (Zn): 43 +/- 16 ppm
  • Iron (Fe): 11,200 +/- 200 ppm
  • Vanadium (V): 1,592 +/- 240 ppm
  • Titanium (Ti): 2,987 +/- 369 ppm

Brown Rubber/Plastic Sole, Bottom of Shoe:

  • Bromine (Br): 10 +/- 5 ppm
  • Zinc (Zn): 125 +/- 29 ppm

Golden Buckle of Shoe:
Note: buckle does not fill up whole scope of XRF so reading includes materials of leather under buckle & metals that are found in the buckle are likely a higher percentage of the metal than what is shown as detected with the XRF as a result.

Also: It is not uncommon to find trace heavy metals (like lead, mercury, cadmium and arsenic) in the buckles and grommets of children’s shoes. I have not been able to find a regulation that addresses the acceptable amount of arsenic (as detectable by an XRF instrument and measured in ppm) in an item intended for use by children in the United States. Please share this information with me if you can find it!

  • Arsenic (As): 134 +/- 12 ppm [confirmed with multiple tests]
  • Arsenic (As): 207 +/- 16 ppm [second test]
  • Barium (Ba): 369 +/- 127 ppm
  • Chromium (Cr): 475 +/- 74 ppm
  • Selenium (Se): 1,178 +/- 52 ppm
  • Tin (Sn): 2,084 +/- 74 ppm
  • Zinc (Zn): 23,700 +/- 500 ppm
  • Copper (Cu): 36,100 +/- 800 ppm
  • Iron (Fe): 2,192 +/- 95 ppm
  • Bismuth (Bi): 84 +/- 13 ppm
  • Vanadium (V): 577 +/- 164 ppm
  • Titanium (Ti): 1,022 +/- 252 ppm

Inside Sole of Shoe (Tan Leather):

  • Barium (Ba): 225 +/- 133 ppm
  • Chromium (Cr): 4,955 +/- 184 ppm
  • Iron (Fe): 609 +/- 56 ppm
  • Titanium (Ti): 8177 +/- 460 ppm

Note: could not test logo on bottom of inside of shoe accurately without damaging / disassembling the shoe.

As always, please let me know if you have any questions.

Thank you for reading and for sharing!
