Table 3.
Urinary fluoride concentrations (mg/L) modeled in a 4-year-old and an 8-year-old child for different exposure scenarios compared with Province-specific CHMS biomonitoring data.
| Province | Scenario | Age-Specific Results | |||||
|---|---|---|---|---|---|---|---|
| 4 year-old Child | 8 year-old Child | ||||||
| Model | CHMS | Ratio 1 | Model | CHMS | Ratio 1 | ||
| Ontario | 1. (Fluoridation of drinking water at 0.7 mg/L) | 0.846 | 0.83 | 1.02 | 0.73 | 0.67 | 1.09 |
| Quebec | 2. (Fluoridation at 0.06 mg/L with dietary intake) | 0.708 | 0.39 | 1.81 | 0.605 | 0.34 | 1.78 |
| Quebec–modified | 3. (Fluoridation at 0.06 mg/L without dietary intake) | 0.574 | 1.47 | 0.48 | 1.41 | ||
1 Ratio of the modeled urinary concentration over the CHMS bio-monitored urinary concentration.
