Table 10. Exposure assessment of detected heavy metals in convenience foods
| Heavy metals | Concentration (mg/kg) | EDI1) (μg/kg b.w./day) | Weekly intake2) (μg/kg b.w./week) | PTWI3) (μg/kg b.w./week) | %PTWI4) | Monthly intake5) (μg/kg b.w./month) | PTMI6) (μg/kg b.w./month) | %PTMI7) |
| Pb | 0.011 | 0.0384 | 0.2689 | 25 | 1.0757 | - | - | - |
| As | 0.0086 | 0.0300 | 0.2103 | 15 | 1.4017 | - | - | - |

Estimated daily intake = residual mean concentration (mg/kg) × 1000 × daily food intake (kg/day) / 66.57 kg (Mean body weight of Korean adults referenced from NHIS, 2024).
Weekly intake = (EDI × 7).
Provisional tolerable weekly intake.
%PTWI = (weekly intake / PTWI) × 100.
Monthly intake = (EDI × 30).
Provisional tolerable monthly intake.
%PTMI = (monthly intake / PTMI) × 100.
