BPA Free Plastics? Experts Not Yet Sure of The Side Effects.


  • BPA free plastics could be equally harmful as plastics produces using BPA.
  • No certainty on safe plastic to use in food industry.

Scientist Cheryl Rosenfeld, University of Missouri, has warned consumers that plastics produced without using Bisphenol A (BPA) could be just as harmful when used in products such as water bottles and food packages. Alternatives like bisphenol S (BPS) are known to be particularly harmful for pregnant women and the unborn child as these chemicals are known to be absorbed through the placenta and can cause long term health complications for the child.

Cheryl Rosenfeld further added, “”More importantly, these chemicals have the ability to lower the placenta’s serotonin production. Lower levels of serotonin can compromise fetal brain development because during this critical time in development the brain relies on the placenta to produce serotonin. Thus, developmental exposure to BPA or even its substitute, BPS, can lead to longstanding health consequences.”

Placenta is the primary source of serotonin, which helps in the fetal brain development. Serotonin is a naturally occurring chemical that can have various psychological effects as well as effects on physical activities such as eating, sleeping, bodily movements etc. The experiment was focused on examining bisphenol S (BPS) effects, an alternative to BPA, on a mouse’s placenta. As the placenta can reveal the history record of what occurred during the development of the fetus, Rosenfeld also believes if chemicals like BPS that are used in the manufacturing of plastics, such chemicals could easily make their way into the developing fetus through the mother’s blood.
