Calculate an adult's daily fluoride intake given these daily items: 2 L/day fluoridated tap water at 0.7 mg/L, one cup brewed black tea contributing 1.0 mg, and accidental swallowing of 0.5 g toothpaste with 1000 ppm fluoride (1,000 µg fluoride per g). Determine total fluoride intake in mg and state whether it exceeds the typical adult RDA range of 3–4 mg.
