Plastics still need a plasticizer, so those BPA-free plastics simply use a chemical like BPA but not studied.

- kurthr 5y agoI don't know about PolyCarobonate, but for LDPE and HDPE (and PET) that sounds incorrect. Certainly, chemists are worried about much smaller amounts of contamination (ppb) than humans and they would definitely know (and measure) how much plasticizer was leaching from their bottles. It appears to be almost none: https://www.thermofisher.com/us/en/home/life-science/lab-plasticware-supplies/plastic-material-selection/low-density-polyethylene-ldpe-labware.html https://www.thermofisher.com/us/en/home/life-science/lab-pla...

Be careful about cherry picking studies that show no harm, you can do it with lead if you really want. The situation isn't as dire, but I think the actual impact on animals is more up in the air than a brief survey of the literature suggests.
- kurthr 5y agoPerhaps, but none of the plastics we're discussing (other than PC) have BPA in them at detectable amounts.
