  1. aArithmetic mean of the results for triplicate tests of all three brands of aluminum pans
  2. bThe results shown are for a child weighing 15 kg based on a daily portion of water (500 mL) or a 10 mL portion of olive oil or citric acid over a period of 1 week (7 days)
  3. cThe results shown are for an adult weighing 70 kg based on a daily portion of water (500 mL) or a 10 mL portion of olive oil or citric acid over a period of 1 week (7 days)
