Abstract
The analysis of residual EDB (ethylene dibromide) in the imported fruits using the Dean-Stark apparatus and ECD-GC was investigated and the following results were obtained: (1) The recovery of EDB was more than 98% by the proposed method. (2) EDB content in mango pulps decreased with the storage time at room temperature (25°C) or in refrigerator (7°C), but the content did not decrease for 6 days by the storage in freezer (-20°C). (3) There were considerable variations in EDB content in mango pulps by the sampling method. (4) The bigger the mango, the higher the residual EDB concentra tion was. (5) EDB content was higher in seeds than in pulps or peels. We also surveyed the concentration of residual EDB in pulps, peels and seeds of the imported fresh fruits (grapefruits, papayas, mangos and litchis) purchased at the fruits-shop in Osaka Prefecture in April to June, 1987.
