“…The same authors (SHRADER et al 1942) found that in commodities high in oil or protein, losses occurred during the ignition step. To overcome this problem, sodium hydroxide pellets were added to the hydrolyzed sample and the combination was heated on a hot plate to accomplish the initial charring.…”

“…GmICH and PEDERSEN ( 1963) studied bromide residues in MB-fumigated wheat and so assumed that all bromides found were inorganic. They modified the official method of the American Association of Cereal Chemists (CHAPMAN et al 1960, MACMASTERS 1962, which is essentially the procedure of SHRADER et al (1942). GmICH and PEDERSEN (1963) evaporated the alcohol from the alcoholic potassium hydroxide added to the sample and then ashed the mixture in a mufHe furnace.…”

“…OLOMUCKI and BONDI ( 1955) removed free EDB from fumigated grains by chloroform extraction. They then used the total bromide method of SHRADER et al ( 1942) to determine the inorganic bromide still in the solids. HEUSER (1961) did not feel their chloroform extraction was sufficient for removing the fumigant, but the authors later presented additional support for their technique [ALUMOT (OLOMUCKI) and BONDI 1962J.…”

“…The condensate was collected in dilute potassium hydroxide and bromide determined. SHRADER et al (1942) felt that this method probably caused a conversion of MB to inorganic bromide during the heating in alcohol. They obtained five to ten percent more inorganic bromide by the method of LAUG (1941) than by their own method.…”

“…2,3) Some inorganic bromide in crops is considered to be a breakdown product of brominated fumigants that are used to control pests. [3][4][5] Residual bromide levels are usually higher in such food than in unfumigated products. 6) Many researchers have focused on inorganic bromide due to the high daily intake from food and drinking water.…”

We examined the contents of different vegetables using X-ray fluorescence spectrometry and found extremely high levels of bromine (Br) [1000-16200 ppm (dry weight)] in some vegetables from an Osaka market. Examination using a bromide ion-selective electrode suggested that the bromine existed mainly as bromide ion. Since this bromine probably originated from fumigation with methyl bromide, this result suggests that fumigation methods may need to be regulated. Fifty milligrams of bromine [aceptable daily intake (ADI)/50 kg] was found in only 3.1 g (dry weight) of komatsuna (Br: 16200 ppm). These results suggest that vegetables that contain potentially harmful levels of bromide may be found in Japanese markets.
