Figure 6From: Estrogenic chemicals often leach from BPA-free plastic products that are replacements for BPA-containing polycarbonate products Concentration-response curves for some common additives. Dose–response curves for 6 additives used in the manufacture of various PC-replacement plastics. Key as for Figure 1. Panels A-F: antioxidants (A-C) tested as individual chemicals; colorants (D), UV stabilizers (E) or inks (F) added to PP bottles or PP plaques. Without the additive, the PP plaques or bottles exhibited no detectable EA (data not shown).Back to article page
