Table 1: E-cigarette Chemical Components Screened in Zebrafish.

The seven most common chemical components detected in six different e-cigarette mixtures from Mount Baker Vapor in Lynden, WA (Tierney et al., 2016) and concentration range tested in zebrafish. Nicotine and the Unflavored cartridges do not appear as neither contained chemicals in addition to PG, VG, and nicotine. Banana Crème Pie flavor is not included in the table as its chemical constituents could not be confirmed.
