Some problems with 1,2-dibromoethane residue analysis

“…Papaya and mango are carried by plane from Hawaii and The Philippines, respectively. As it is wellknown that EDB residue level in fruits decreases very rapidly with time (King et al, 1980;Sekita et al, 1983), the assays were performed on the day of arrival.…”

“…Procedures. Principally the procedures used followed the method of Sekita et al (1981). Pretreatment of fruits was carried out according to A and B. Pretreatment A: Analytical portions of fruits were cut into small pieces, put into a blender cup, and then blended for 30 s for homogeneity at room temperature at 5X (rpm) of a propeller blade and at 5X (rpm) of an eccentric spin of blender cup.…”

“…In Japan a method using the combination of a distillation apparatus, which had been devised by Bielorai and Alumot (1966), and steam distillation with n-hexane has been used as a Japanese official method since 1981 (Sekita et al, 1983). This paper deals with some problems on EDB analysis depending on the results obtained by applying this method to fruits.…”
