PESTICIDE RESIDUES IN FOOD - 1979


    Sponsored jointly by FAO and WHO






    EVALUATIONS 1979





    Joint meeting of the
    FAO Panel of Experts on Pesticide Residues
    in Food and the Environment
    and the
    WHO Expert Group on Pesticide Residues
    Geneva, 3-12 December 1979



    FENTHION

    Toxicology

    Although fenthion is scheduled for evaluation at the 1980 meeting,
    information was available on the influence of fenthion on the eyes, as
    indicators of effects on the central nervous system.  Four days after
    injection of this compound at dose levels of less than 0.5 mg/kg bw,
    the main changes in the electroretinography (ERG) were a shortening in
    the latency time of the alpha wave, a shortening in the peak times of
    the alpha and beta waves, and an increase in the amplitude of the
    waves.  The dose effecting minimum changes in the ERG was 0.005 mg/kg
    bw (Iami, II, Toxicity of organophosphorus pesticides - fenthion - on
