These monographs summarize the safety data on selected food additives and contaminants reviewed by the Committee. Generally, the compounds on which monographs were prepared are those on which substantial safety data exist. The data reviewed in these monographs form the basis for acceptable daily intakes (ADIs) established by the Committee. The thirtieth report of JECFA has been published by the World Health Organization in the WHO Technical Report Series (No. 751). The participants in the meeting are listed in Annex 3 of the present publication and a summary of the conclusions of the Committee is included as Annex 4. Specifications established by the thirtieth JECFA have been issued separately by FAO under the title Specifications for the identity and purity of certain food additives, FAO Food and Nutrition Paper, No. 37. These toxicology monographs should be read in Conjunction with the specifications and the report. Reports and other documents resulting from previous meetings of the Joint FAO/WHO Expert Committee co Food Additives are listed in Annex 1. JECFA serves as a scientific advisory body to FAO, WHO, their Member States, and the Codex Alimentarius Commission, primarily through the Codex Committee on Food Additives, regarding the safety of food additives and contaminants in food. Committees accomplish this task by preparing reports of their meetings and publishing specifications and toxicological monographs, such as those contained in this volume, on substances that they have considered. The toxicological monographs contained in this volume are based upon working papers that were prepared by temporary advisers in advance of the 1986 JECFA meeting. A special acknowledgement is given to those who prepared these working papers: Dr C. L. Galli, Professor of Experimental Toxicology, University of Milan, Milan, Italy; Dr S.L. Shibko, Associate Director for Regulatory Evaluation, Center for Food Safety and Applied Nutrition, Food and Drug Administration, Washington, DC, USA; and Dr Ronald Walker, Professor of Biochemistry, University of Surrey, Guildford, Surrey, England. Many proprietary unpublished reports are referenced. These were voluntarily submitted to the Committee by various producers of the food additives under review and m many cases these reports represent the only safety data available on these substances. The temporary advisers based the working papers they developed on all the data that were submitted, and all these studies were available to the Committee when it made its evaluations. From 1972 to 1975 the toxicology monographs prepared by Joint FAO/WHO Expert Committees on Food Additives were published by WHO in the WHO Food Additives Series; after 1975 this series became available only in the form of unpublished WHO documents provided on request by the Organization. Beginning with the 1985 monographs, they are published by Cambridge University Press, which should ensure that these monographs are more widely known and available. The preparation and editing of the monographs included in this volume have been made possible through the technical and financial contributions of the Participating Institutions of the International Programme on Chemical Safety (IPCS), which support the activities of JECFA. IPCS is a joint venture of the United Nations Environment Programme, the International Labour Organisation, and the World Health Organization, which is the executing agency. One of the main objectives of IPCS is to carry out and disseminate evaluations of the effects of chemicals on human health and the quality of the environment. 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 organizations participating in 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 those organizations in preference to others of a similar nature that me not mentioned.
