INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY
The preparatory work for the toxicological evaluations of pesticide
residues carried out by the WHO Expert Group on Pesticide Residues
for consideration by the FAO/WHO Joint Meeting on pesticide Residues
in Food and the Environment is actively supported by the
International Programme on Chemical Safety (IPCS).
The International Programme on Chemical Safety (IPCS) is a joint
venture of the United Nations Environment Programme, the
International Labour Organisation, and the World Health
Organization. One of the main objectives of the IPCS is to carry out
and disseminate evaluations of the effects of chemicals on human
health and the quality of the environment.

INTRODUCTION
The toxicology monographs and monograph addenda contained in this
volume were prepared by a WHO Expert Group on Pesticide Residues that
met with the FAO Panel of Experts on Pesticide Residues in Food and the
Environment in a Joint Meeting on Pesticide Residues (JMPR) in Geneva,
Switzerland, 21 September to 30 September 1987. These monographs
summarize the safety data on those pesticide residues for which
sufficient information was provided to the WHO Expert Group for it to
make decisions regarding acceptable daily intake.
Most of the compounds considered by the WHO Expert Group at this
Meeting had been evaluated at previous meetings and monographs on them
have been published previously. In such cases, only new information is
summarized in the relevant "monograph addenda". Reference is made to
reports and other documents resulting from previous Joint Meetings of
the FAO Panel of Experts on Pesticide Residues in Food and the
Environment and WHO Expert Groups on Pesticide Residues, which are
listed in Annex 1. The appropriate documents should be consulted to
obtain a full toxicological profile of the chemicals under
consideration.
The report of the Joint Meeting has been published by the Food and
Agriculture Organization (FAO) of the United Nations as FAO Plant
Production and Protection Paper No. 84. The report contains brief
comments on the compounds under consideration, acceptable daily intakes
established by the WHO Expert Group, and maximum residue limits or
guideline levels established by the FAO Panel of Experts. Residues
monographs prepared by the FAO Panel of Experts have been published as
a companion volume to this one, Evaluations 1987, Part I Residues, as
FAO Plant Production and Protection Paper No. 86/1.
The toxicology monographs and monograph addenda contained in this
volume are based upon working papers that were prepared by temporary
advisers in advance of the 1987 Joint Meeting. A special acknowledgement
is given to those who prepared these working papers, Professor C.L.
Berry, The London Hospital Medical College, London, UK, Dr A.L. Black,
Commonwealth Department of Health, Woden, Australia; Dr M. Manno,
University of Padua Medical School, Padua, Italy, Dr D.S. Saunders, U.S.
Environmental Protection Agency, Washington, DC, USA, and Dr E.M. den
Tonkelaar, National Institute of Public Health and Environmental
Hygiene, Bilthoven, The Netherlands.
The preparation and editing of the monographs included in this
volume have been made possible through the technical and financial
contributions of the lead Institutions of the International Programme on
Chemical Safety (IPCS), which support the activities of JMPR. The
designations employed and the presentation of the material in this
publication do not imply the expression of any opinion whatsoever on the
part of the Central Unit of the IPCS concerning the legal status of any
country, territory, city, or area or its authorities, or concerning the
delimitation of its frontiers or boundaries. The mention of specific
companies or of certain manufacturers' products does not imply that they
are endorsed or recommended by the IPCS in preference to others of a
similar nature that are not mentioned.
Any comments or new information on the biological or toxicological
data on the compounds reported in this document should be addressed to:
