Most plastics release estrogenic chemicals according to paper published in Environmental Health Perspectives

March 11th, 2011 by Environmental Health Perspectives

A paper published in March 2011 in the peer-reviewed open-access monthly journal Environmental Health Perspectives finds that most plastics contain chemicals with estrogenic activity that leach even if they are advertised as Bisphenol A (BPA) free.

The paper “Most Plastic Products Release Estrogenic Chemicals: A Potential Health Problem That Can Be Solved” states that “almost all commercially available plastic products sampled, independent of the type of resin, product, or retail source, leached chemicals having reliably-detectable Estrogenic Activity, including those advertised as BPA-free.”

“In some cases, BPA-free products released chemicals having more estrogenic activity than BPA-containing products.” “Chemicals having estrogenic activity (EA) reportedly cause many adverse health effects, especially in fetal and juvenile mammals.”

Stephen Ritter of Chemical & Engineering News has published a summary of the paper’s findings.  He writes that the researchers “found that about 70 percent of the plastic items tested positive for estrogenic activity.”

He goes on to write that “when the researchers stressed the materials under “real world” conditions of simulated sunlight, microwaving, and dishwashing, about 95 percent of the products tested positive, including most of the products labeled as BPA-free.”


Sustainable Guernsey believes that we may wish to minimise our use of plastic packaging and be particularly careful about minimising our production of plastic litter.
