Abstract
A solute mass-balance study of ground water of the 3000 km2 coastal sabkhat (salt flats) of the Emirate of Abu Dhabi, United Arab Emirates, documents an annual bromide loss of approximately
255 metric tons (0.0032 Gmoles), or 85 kg/km2. This value is an order of magnitude greater than previously published direct measurements from the atmosphere over an evaporative
environment of a salar in Bolivia. Laboratory evidence, consistent with published reports, suggests that this loss is by vapor
transport to the atmosphere. If this bromine flux to the atmosphere is representative of the total earth area of active salt
flats then it is a significant, and generally under recognized, input to the global atmospheric bromide flux.
