FAO/PL:1968/M/9/1 WHO/FOOD ADD./69.35 1968 EVALUATIONS OF SOME PESTICIDE RESIDUES IN FOOD THE MONOGRAPHS Issued jointly by FAO and WHO The content of this document is the result of the deliberations of the Joint Meeting of the FAO Working Party of Experts and the WHO Expert Committee on Pesticide Residues, which met in Geneva, 9-16 December, 1968. FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS WORLD HEALTH ORGANIZATION Geneva, 1969 CARBON DISULFIDE This pesticide has been previously evaluated (FAO/WHO, 1965, 1968); however, no recommendations for acceptable daily intake or tolerances were made. Since that time additional studies have raised further problems which are outlined below. RESIDUES IN FOOD AND THEIR EVALUATION The meeting noted the importance of halogenated hydrocarbons and other fumigants in developing countries, especially for use on farms. Earlier meetings had recommended tolerances for inorganic bromide resulting from the use of methyl bromide and ethylene dibromide but had stressed the importance of avoiding or eliminating detectable residues of unchanged fumigants such as ethylene dibromide (CH2Br CH2Br), methyl bromide (CH3Br) and carbon tetrachloride (CCl4). This matter had been referred through FAO to the Pesticide Section of the International Union of Pure and Applied Chemistry (IUPAC) with a view to obtaining more precise information on the residual levels of unchanged fumigants. Experiments in which whole wheat grain was fumigated with a mixture of carbon disulfide, carbon tetrachloride, trichloroethylene (C2HCl3) and methyl bromide indicated that detectable residues of carbon disulfide and carbon tetrachloride might persist for months despite aeration, milling, baking, etc. (IUPAC, 1968). Therefore, the meeting wished to draw the attention of Member governments to the need for further work on the toxicity of these unchanged fumigants and on their levels in food under various practical conditions of use. Further work or information Required (before acceptable daily intakes, tolerances or negligible residue levels can be established). Information on the level of residues that may persist in the unchanged form after processing treated food products. REFERENCES FAO/WHO.
