Introduction:
Tamara Rubin is an independent advocate for consumer goods safety, and 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).

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!)

Do Tiblue tumbler like cupkin’s contains lead? They look like they would come out of the same fabrication.
