    ANNEX I

    ACCEPTABLE DAILY INTAKES, MAXIMUM RESIDUE LIMITS AND GUIDELINES
    LEVELS PROPOSED AT THE 1981 MEETING

         These figures are additional to, or amend, those recorded in
    Annexes of the reports of earlier meetings. Limits recommended at
    meetings from 1965 - 1977 inclusive are summarized in document FAO/WHO
    1978c.

         This table includes maximum acceptable daily intake (ADIs),
    maximum residue limits (MRLs) and guideline levels (GLs). These terms
    are defined in Annex 3 of the Report of the 1975 Meeting. Part I lists
    ADIs and MRLs. Some ADIs and MRLs are temporary; in these cases the
    year in which further data are required is specified in parenthesis
    below the ADI. Part II lists GLs.

         New, as distinct from amended, recommendations are identified by
    the symbol * before the commodity or before the ADI. Residue levels
    at or about the limit of determination are followed by the symbol
    **. (see para. 2.4)

         Certain corrections of previous publications are included.

         Amended recommendations are followed by the previous
    recommendation in parenthesis.
