TI  - Relationship between physicochemical properties and maximum residue levels and 
      tolerances of crop-protection products for crops set by the USA, European Union 
      and Codex.
PG  - 764-76
AB  - Residues on foodstuffs resulting from the use of crop-protection products are a 
      function of many factors, e.g. environmental conditions, dissipation and 
      application rate, some of which are linked to the physicochemical properties of 
      the active ingredients. Residue limits (maximum residue levels (MRLs) and 
      tolerances) of fungicides, herbicides and insecticides set by different 
      regulatory authorities are compared, and the relationship between physicochemical 
      properties of the active ingredients and residue limits are explored. This was 
      carried out using simple summary statistics and artificial neural networks. US 
      tolerances tended to be higher than European Union MRLs. Generally, fungicides 
      had the highest residue limits followed by insecticides and herbicides. 
      Physicochemical properties (e.g. aromatic proportion, non-carbon proportion and 
      water solubility) and crop type explained up to 50% of the variation in residue 
      limits. This suggests that physicochemical properties of the active ingredients 
      may control important aspects of the processes leading to residues.
