Introduction to Tamara Rubin
(for those new to this website!)

Tamara Rubin lives in Portland, Oregon and is a child health advocate, author, documentary filmmaker, and mother of four sons. Her young men are now 24, 18, 15, and 12. She has won multiple national awards for her Lead-poisoning prevention advocacy work (including two from U.S. government agencies). In 2020 she had more than 1.165 million unique individual readers visit her #LeadSafeMama blog – from more than 200 countries (per Google Analytics) around the world!

It is with the help, support, and participation of these readers that she conducts and reports on independent testing of consumer goods for toxicants (Lead, Mercury, Arsenic, Cadmium, and Antimony), using high-accuracy X-Ray Fluoresence analysis (read more about that here). She goes by #LeadSafeMama on Twitter, Facebook & Instagram and has over 2,700 separate posts of information (mostly consumer goods test results) on her blog here at LeadSafeMama.com.

Tamara’s advocacy work has been mentioned in print in The New York Times; the New York Post; Mother Jones; Parents Magazine; Vice.com; MNN.com; TruthOut; WebMD; the Huffington Post,;USA Today; Grok Nation, and more (too many outlets to list!) – and in other media (T.V. and radio), on the Today Show; Kids in the House; Al Jazeera English; The Voice of Russia; CBS This Morning, and through news stories on CBS; ABC; NBC, and even Fox News – as well as in countless podcasts and other interviews.

“Tamara, tell me more about this testing…”

Testing is done with the same instrumentation used by the Consumer Product Safety Commission to test consumer goods for Lead (and other toxicants), when screening for safety (including screening items intended for use by children to make sure they fall within acceptable levels.) All tests are done for a minimum of 60 seconds unless otherwise noted. Tests are repeated multiple times on each component to confirm the results. Test results are science-based, accurate and replicable.

As always, please let me know if you have any questions. With 1.165 Million unique readers in 2020 alone I am not always able to answer each and every question personally, but I do try. Thank you.
