    RESIDUES

    Explanation

         The Codex Committee on Pesticide Residues requested the Meeting
    to reconsider the definition of the residue. The original data
    submitted to the 1972 Meeting1 and some additional data were studied,
    The relevant information is summarized in this re-evaluation.

    RESIDUES RESULTING FROM SUPERVISED TRIALS

         The results of supervised trials carried out in beans, oilseed,
    rape, cotton and citrus fruit indicate that the oxygen analogue of the
    parent compound and its relevant sulphoxide and sulphone are either
    present in very low concentrations or are not detectable.
    Consequently, they can be excluded from the definition of the residue.
    The proportion of parent compound in the total residue was also
    considered. However, most of the results obtained in supervised trials
    were presented as a sum of sulphoxide and sulphone. Therefore, the
    estimation of maximum residue levels (MRLs) based on the parent
    compound alone was not possible.

    RECOMMENDATION

         The Meeting concluded that the oxygen analogue of the parent
    compound and its relevant sulphoxide and sulphone can be excluded from
    the definition of the residue. The MRLs, which remain the same, refer
    to the sum of carbophenothion, its sulphoxide and sulphone, expressed
    as carbophenothion.
