EA of PC-replacement products assessed by MCF-7 or BG1Luc assays. Means of highest value and SD of %RME2 from dose–response curves of various extracts of acrylic, COC, COP, PES, PS PC-replacement products as stated in key to each panel. Number of independent assays for each type of product extract (e.g., EtOH concentration, saline) given above the bar graph. Each assay consisted of three replicates for that extract whose SD was typically very small (as indicated in Figure 1). Unstressed = UN, AU = autoclave stress, MI = microwave stress, UVA and UVC = long and short wavelength UV stresses, respectively. Each assay for each product is considered by itself whether its EA is significantly greater than its VC or SC EA, i.e. > 15%RME2 (see Methods). We do not statistically compare EA values obtained for different plastic products because extraction procedures and concentrations, while similar, are not exactly the same. PC-replacement products.
