For those new to this website:
Tamara Rubin is a multiple-federal-award-winning independent advocate for childhood Lead poisoning prevention and consumer goods safety, and a documentary filmmaker. She is also a mother of Lead-poisoned children (two of her sons were acutely Lead-poisoned in 2005). Since 2009, Tamara has been using XRF technology (a scientific method used by the U.S. Consumer Product Safety Commission) to test consumer goods for toxicants (specifically heavy metals — including Lead, Cadmium, Mercury, Antimony, and Arsenic). Tamara’s work was featured in Consumer Reports Magazine in February 2023 (March 2023 print edition).
When tested with an XRF instrument, this Washington State ceramic bag Christmas ornament with a green ribbon (Who actually thought of this? Why is this a thing?!) — purchased new at a Starbucks store in Washington in 2019 — had the following readings:
- Cadmium (Cd): 433 +/- 24 ppm
- Barium (Ba): 999 +/- 202 ppm
- Chromium (Cr): 4,182 +/- 183 ppm
- Lead (Pb): Non-Detect / Negative
- Mercury (Hg): Non-Detect / Negative
- Arsenic (As): Non-Detect / Negative
- Antimony (Sb): Non-Detect / Negative
- Selenium (Se): Non-Detect / Negative
All tests were completed for a minimum of 60 seconds each using a freshly calibrated Niton XRF instrument (an XL3T XRF testing in “Consumer Goods” mode). Tests were repeated multiple times to confirm the results. All test results reported on this website are science-based, accurate, and replicable.
