This report presents the modified method of our previous paper where methyl bromide (MB) liberated from crops by Malone's method was determined with glc after its derivatization to O, O-diethyl S-methyl dithiophosphate with ammonium O, O-diethyl dithiophosphate. In the previous procedure, using acetone, it was proved that O, O-diethyl S-methyl dithiophosphate was produced by means of sunlight irradiation or occasionally by means of heating in the absence of MB. Hence, by using N, N-diethyl formamide instead of acetone it became possible to avoid this undesirable phenomenon. Recoveries were 75.7-87.0% from hay and eggplant fortified at a level of 0.05-0.25 ppm, with a detection limit of 0.0003-0.002 ppm. This method made it possible to eliminate the drying tube from Malone's apparatus, and also possible to carry out the operation without excessive cooling of the MB scavenge reaction tubes.
