摘要： @@ Distribution of pesticide residues in crop units plays an important role in estimation of short-term dietary intake and the emulation of sampling uncertainty. The international estimation of shortterm dietary intake methods is based on the 97. 5th percentile of distribution of residue in crop units. The 97. 5th percentile is not measured directly, but estimated by determination the concentration in a composite sample and multiplying it by a 'variability factor' to estimate the 97. 5th percentile level.
