TMDI: Theoretical Maximum Daily Intake. STMR: Supervised Trial Median Residues. Brew Factor (BF) = Residues in tea brew ÷ Residues in dry tea leaves. ADI: Acceptable Daily Intake * Calculated according to the data in Table 3. Those exceeding the ADI value are shown in bolt black. ** countries from where tea came to Turkey. —In this country, the Brew Factor for this pesticide has not been reported.
