This post is a third data set to accompany the original post I did about the BOO [Black Oxygen Organics Fulvic Acid Powder] product. Please click through to this link to read the full details about the test results shared here on the Lead Safe Mama website – including for this sample – and the potential implications. 

One full set of XRF levels for the sample tested:

120-second test (two minutes)

• Lead (Pb): non-detect (below 2,000 ppb)*
• Cadmium (Cd): 13,000 ppb (+/- 1,000 ppb) – known carcinogen
• Mercury (Hg): non-detect (below 4,000 ppb)*
• Bromine (Br): non-detect (below 2,000 ppb)*
• Chromium (Cr): non-detect (below 80,000 ppb)*
• Iron (Fe): 6,944,000 ppb (6,944 +/- 82 ppm)
• Zinc (Zn): 52,000 ppb (52 +/- 4 ppm)
• Niobium (Nb): 349,000 ppb (349 +/- 5 ppm)
• Indium (In): 14,000 ppb (14 +/- 2 ppm)
• Tin (Sn): 9,000 ppb (9 +/- 2 ppm)
• Antimony (Sb): 5,000 ppb (5 +/-3 ppm) – known carcinogen 
• *2 ppm (or 2,000 ppb which is the equivalent measurement to a different level of specificity) is is the limit of detection (the low threshold of detection possible) for the testing methodology employed by Lead Safe Mama, LLC – a testing methodology which is distinct from laboratory “digestive” testing… so any negatives noted here are not “true negatives” – they are non-detect, within the noted limit of detection.
• For example “below 3,000 ppb” might possibly still be 2,000 or 2,500 ppb – which would be an extraordinarily high level of Mercury for something that might be intentionally ingested – especially if it is ingested daily.
• That is not to say that those metals ARE present at the lower levels, but more testing using different testing methodologies is required to determine the presence or absence of those metals.
• Metals not listed above were not detected (within the limits of the technology used).
• All metals detected using the XRF instrumentation employed by Lead Safe Mama, LLC are listed above.
• Again – to restate – the metals listed as “non-detect” (& others) are possibly present at quantities that fall below the numeric values noted. That means the levels could be present at quite high amounts for a supplement but that is still below the level of detection of this instrument and follow up laboratory testing would be required to determine the presence or absence of these metals (and to determine a quantity if present.)
• XRF testing results in readings in parts per million (ppm). Ideally supplements should be tested in a lab down to more sensitive levels with a low threshold of detection of 1 part per billion (ppb). Please read the linked posts within this post (above) to better understand these considerations.
• All test results reported on this website (for any product we test) are for samples that were tested multiple times to confirm the results (so there were multiple test results showing the same or similar levels of metals as the one test results set listed above.) The results are replicable, accurate and science-based (within the limits of detection for the instrument used as discussed above.)

Again, here is the full post for context for the above readings.

Tamara’s sons were acutely Lead-poisoned in August of 2005. 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. Tamara uses XRF testing (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.

Items are tested multiple times to confirm the test results for each component tested. Please click through to this link to learn more about the testing methodology used for the test results discussed and reported on this website.
