    INTRODUCTION

    A Joint Meeting of the FAO Working Party of Experts on Pesticide
    Residues and the WHO Expert Committee on Pesticide Residues was held
    in Geneva in December 1968. The general considerations, including the
    principles adopted for the evaluations and a summary of the results of
    evaluations on a number of pesticide residues will appear in a
    publication entitled "Report of the 1968 Joint Meeting of the FAO
    Working Party of Experts on Pesticide Residues and the WHO Expert
    Committee on Pesticide Residues".* Additional information, including
    previously unpublished summaries of data considered by the Joint
    Meeting in arriving at recommendations for acceptable daily intakes,
    tolerances and methods of analysis, is to be found in this document.

    Many of the compounds considered at this meeting have been previously
    evaluated in earlier publications. If only a limited amount of
    additional data on these compounds has become available in the
    intervening years, only this latter data is summarized in the
    pertinent monograph and reference is made to the previously published
    evaluation which should also be consulted by the reader who wishes to
    obtain a complete evaluation of the compound. If a large amount of
    data has become available since the previously published evaluation,
    or if the compound was first considered by the Joint Meeting in 1968,
    the pertinent monograph is reproduced in its entirety.

    As much relevant information as possible has been included in the
    monographs. Wherever possible this has been obtained from the
    published literature, but other sources of information have also been
    used. Early and complete publication of the results of research in
    this field is very important, particularly of that part which could
    form the basis for estimation of acceptable daily intakes and
    appropriate tolerances.

    Publication allows the research to be scrutinized and criticized by
    scientists from disciplines not necessarily represented at the
    meeting. Data contained in unpublished reports, because they may
    include more detail than published work, are often acceptable.
    However, such reports must be complete and non-confidential and
    indicate authorship.

    FAO Working Party of Experts on Pesticide Residues and the WHO Expert
    Committee on Pesticide Residues, FAO Agricultural Studies, No. 78, WHO
    Technical Report Series, No. 417.

    Two annexes have been included at the end of this series of
    monographs. Annex I is a reproduction of Annex I in the Report of the
    1968 Joint Meeting* and gives the source of all the previous
    monographs of various compounds. Annex II comprises a definition of
    terms, most of which were included in the Report of the 1967 Joint
    Meeting.** Two additional terms, namely "regulatory" and "referee"
    methods of analysis are also defined in this annex.
