Our Stolen Futurea book by Theo Colborn, Dianne Dumanoski, and John Peterson Myers



background on bisphenol A

Miyakoda, H, M Tabata, S Onodera and K Takeda. 1999. Passage of bisphenol A into the fetus of the pregnant rat. Journal of Health Science 45(6):318-323.


Orally administered bisphenol A (10 ppm) appears immediately in maternal blood and is transferred into the fetus. The concentration of BPA in the fetus peaked within one hour after administration, reaching 11 ppb. in fetal blood.

This paper suggests that BPA passes easily through the placental barrier, bypassing protections that limit the impact of native estradiol and phytoestrogens.
