## Abstract The effect of methyl bromide on some of the Bβvitamins, both in aqueous solution and in foodstuffs, has been studied. From analyses of the bromide residues, it appeared that some reaction had occurred in those solutions of nicotinic acid and nicotinamide that had been treated with high
Cereal seeds of various varieties which had been fumigated a t one of four moisture contents were kept for 6 years. The germination capacity of the samples was determined initially and again after 6 months, 3 years and 6 years of storage. At the lowest moisture contents good survival of fumigated an
The persistence of methyl bromide (MB) in white rice, brown rice, sultanas, raisins, pumpkin seeds, brazil nuts, groundnuts and walnuts was monitored following laboratory fumigations at different concentration time products and temperatures. A sensitive automated headspace gas chromatographic method
