Table 2 Frequency of EA leaching from PC-replacement products

From: Estrogenic chemicals often leach from BPA-free plastic products that are replacements for BPA-containing polycarbonate products

Ratio of EA + products/total tested for each stress
Product type n UN MI AU UV Overall
Acrylic 3 2/3   2/3 2/3 2/3
COC 4 0/3 0/1 0/2 0/2 0/2
COP 1 0/1 0/1 0/1 0/1 0/1
PES 3 0/1 1/1   3/3 3/3
PETG 3   0/3 0/3 1/3 1/3
PS 11 9/11   0/1 2/3 9/9
Tritan™ 25 2/6 3/10 3/14 23/25 23/25
Total 50 13/25 4/16 5/24 31/40 38/46
  1. Relative number of products made from a resin type exhibiting significant (p < 0.01) EA for a given stress or for any stress.
  2. Row labeled “overall” gives the number of products exhibiting EA for those products having at least three assays for at least 3 stresses (row labeled “Overall”).
  3. Row labeled “Total” sums the data for that column.
  4. n: number of products tested for any stress condition, blank column: no tests made for that particular combination of product and stress, UN: unstressed, MI: microwaved, AU: autoclaved, UV: UVA or UVC stress.
