CDC & EPA Proves Flameproof Mattresses Toxic

I wrote to the CDC asking what level of Antimony exposure is safe. I got a reply from the CDC:  “ATSDR [Agency for Toxic Substances & Disease Registry] has not derived a chronic MRL [Minimal Risk Level] for antimony. However, the U.S. EPA chronic oral reference dose for antimony is 4E-4 mg/kg/day.” This is .0004 mg/kg/day, or 4/10,000’s of a milligram/ per kilogram of body weight/ per day. This is a far different number than the CPSC assumption of a safe level of 2.3 mg/kg/d. In fact, it is 5,750 times more than the EPA minimal risk number. It also changes everything and proves our antimony absorption from flame proof mattresses is unsafe by 27.5 times.

Comparing these numbers to the CPSC assumptions in their table 16, tab d, p 45, shows:

CPSC tests prove we will absorb 0.011 mg/kg/d of Antimony from new flame proof mattresses. The only question is what is a safe level? The CPSC says 2.3 mg is safe while the EPA says only .0004 is a safe level. If we accept the EPA number it proves new mattresses are toxic by 27.5 times more than the safe level.

The CDC points out: “ATSDR has not derived a chronic MRL [Minimal Risk Level] for antimony.” They can not derive one because as stated in their health effects document on Antimony they say: “At the lowest exposure levels tested, the adversity of the effects was considered to be serious.”

It seems clear the CPSC is trying to prove poison laden mattresses are safe. There are many other problems with this risk assessment. Again over TERA’s (the independent reviewer) objections they changed all the rules of the child sucking test to obtain lower numbers. We believe Boric Acid would fail a properly designed child sucking test, with realistic exposure data. This test is designed to protect a one year old child. The CPSC did not even consider children under five in their risk assessment.

The CPSC says: “As with any risk assessment, there are assumptions, limitations, and sources of uncertainty. … It should be noted that percutaneous [skin] absorption data were not available for antimony.” The CPSC assumes a Percutaneous (Skin) absorption rate of only .002 per hour of the chemical that has leached or migrated to the surface of our mattresses and is in contact with our bodies. This is only 2/1,000’s of the available chemical. This seems a very small number. The correct number might be much higher and we may absorb much more than the CPSC calculations predict.

Antimony Trioxide accumulates in our bodies. When pressed by TERA about the cancer risk from Antimony Trioxide the CPSC admits: “The cancer effects are cumulative. Every exposure contributes to the overall lifetime risk of developing cancer.”

The CDC and the EPA has proven CPSC safety assumptions wrong. They have also proven CPSC exposure and absorption calculations of poison absorbed from flame proof mattresses will exceed toxic levels by 27.5 times.
