- Almost the entirety of the claims are based on samples that have been rapidly "stressed" in someway to "simulate" stresses that would naturally occur to the plastic over longer periods of time during normal use.
- Unfortunately, there is no effort made to understand if the aging that occurred in the rapidly-stressed plastics resembled in anyway the aging that would occur in naturally-stressed plastics.
- Verifying that there is no aging difference between the rapidly-stressed and the naturally-stressed samples is critical since at no point are the specific EA chemicals identified.
- This means we do not know if the EA chemicals are artificially-introduced artefacts from the extreme stress conditions or not.
- This means that we cannot accurately make statements that BPA-free plastics, when used in a normal manner, will also show EA.
That's enough talk about estrogenic activity in plastics for a while.
