  1. aCalculated for all agents using the following formula with the risk functions defined in Table 4:
  2. Exposure = Risk function of concentration * Risk function of e-cigarette liquid amount per day * Risk function of vaporization percentage / Risk function of bodyweight (kg).
  3. The risk function of e-cigarette liquid amount per day was RiskNormalAlt(25%;3;75%;5;RiskTruncate(0;)) based on values from Farsalinos et al. [40]
  4. The risk function of vaporization percentage was RiskUniform(6;81) based on values from Goniewicz et al. [19].
  5. The risk function of bodyweight was RiskNormal(73.9;12) according to average and standard deviation from EFSA Scientific Committee [41].
