2. The death rate in England is much lower than the United States, since a link to a possible accidental poisoning was identified and made public by the media.

3. A poor, unmarried mother's risk of having an unexplained infant death is 3 times greater than that of a married mother. This risk increases for each subsequent child.  Afro-Americans have a risk that is 3 times greater than Caucasians.  Daycare Centers are now becoming a focus according to the American Academy of Pediatricians.

4. An older previously used mattress is in all likelihood related to unexplained infant deaths, because studies indicate the incidence is 2-3 times greater than for new mattresses. 

5. Poorer mothers, Afro-American mothers and daycare centers usually have little choice but to constantly re-use crib mattresses. The older age may be directly related to morbidity and mortality.

6. Crib mattresses, since the early 1950's, are usually made from polyvinyl chloride (PVC), which contains chemical compounds composed of phosphorus, arsenic and antimony. 

7. The gas forms of these three chemical compounds, even in small amounts, are extremely toxic, especially to newborns.

8. The gases of these compounds can appear naturally in our environment by a process of biodegradation. Mildew or molds can release these gases.

9. These poisonous gases have been demonstrated in the laboratory when PVC and mildew, taken from used crib mattresses, are incubated together.

10. Tissue samples among babies who have died in England from unexplained reasons have shown high antimony levels. Antimony is not found in significant amounts in food or water.  Crib mattresses are the only possible source. 

11. Babies, who have died from known causes, studied at the same time, did NOT demonstrate higher antimony levels.  

12. The evidence for a gas poisoning explanation may have been reinforced by the Back to Sleep program. Turning a baby's face 180 degrees away from the mattress has reduced the unexplained death rate by 38%. Unfortunately the fact remains that babies continue to die even on their backs.  The majority of babies, it deserves to be noted, are able to roll onto their tummies by age 5 months.

13. A polyethylene protective cover or a chemical free mattress has been widely used in New Zealand.  Since 1995 no baby protected from the PVC/mildew environment by polyethylene has died for unexplained reasons..

14. A group of children in England, who survived the first year of life, have been shown to have higher than normal antimony levels. Antimony has properties similar to lead. No one has studied the potential danger of high antimony levels.

15. Research efforts in England designed to disprove "an accidental poisoning" explanation for unexplained deaths have not been totally successful, in spite of editorial claims to the contrary.
