title: Estimation methods for Maximum Residue Limits for pesticides.
abstract: Maximum Residue Limits (MRLs) are standards that represent the maximum residue concentration expected to be found if a pesticide is applied according to good agricultural practice (GAP). MRLs are established only where the residues in food resulting from particular use patterns of the pesticide pass the public health risk assessment. Foodstuffs are monitored for MRL compliance and MRL exceedance can have economic and trade consequences. There is a trade-off when deciding on values for MRLs. The aim is to establish MRLs at levels that are high enough to prevent chance exceedance but not so high that misuse will not be detected. Small data sets typically available for estimating MRLs present problems for establishing consistent values. A review of MRL estimation methods is presented together with an assessment of the various methods.
