SAMPLING AND ANALYSIS OF SELECTED TOXIC SUBSTANCES. TASK IV - ETHYLENE DIBROMIDE

Sites representing six categories of potential sources of EDB emission were sampled. The categories are: (1) gasoline mixing, storage, and transfer (refineries); (2) retail gasoline; (3) highly trafficked urban; (4) suburban residential (lightly trafficked); (5) rural; and (6) fumigation centers. Air samples collected near four different bulk loading stations had EDB levels at least twice that of background samples. The effect of heavily trafficked freeways on the EDB levels in two different cities was not discernible. However, EDB was detected in all samples taken in heavily trafficked urban areas. The ubiquitous nature of EDB is probably the result of the widely dispersed sources of emission in urban/industrial areas. The levels of EDB in air ranged from 0.05 to 0.10 microgram/cum in rural and suburban areas, and from 0.1 to 0.4 microgram/cum in metropolitan areas. Two fumigation centers where EDB was used to fumigate grapefruit were found to be significant sources of emission.
