Table 2: E-cigarette Flavor and Component EC50 Values for Mortality at 120 hpf.
Bubble Gum and Grape as well as their mixture components: ethyl acetate, ethyl buytrate and cinnamaldehyde, in addition to the component-based mixtures created in the study, were tested. For the Grape mixture and ethyl acetate, we were unable to estimate EC50 due to the lack of mortality. Ethyl acetate + ethyl butyrate = EA+EB; ethyl acetate + ethyl butyrate + cinnamaldehyde = EA+EB+C; Grape mixture + cinnamaldehyde = G+C.
| Chemical or Mixture | Estimated EC50 Value |
|---|---|
| Bubble Gum Flavor | 1:100 dilution factor |
| Grape Flavor | NA (dilution factor) |
| Ethyl Acetate | NA μg/mL |
| Ethyl Butyrate | 117 μg/mL |
| Cinnamaldehyde | 11.4 μg/mL |
| EA+EB | 406 μg/mL |
| EA+EB+C | 101 μg/mL |
| G+C | 28.6 μg/mL |
