The partitioning of bromine in the lower troposphere between particulate, inorganic gaseous, and organic gaseous phases was measured during the arctic spring. Rapid photochemical production of particulate Br[sup [minus]] from organic gaseous Br was indicated by (1) an inverse correlation between particulate bromide and organic gaseous bromine (r[sup 2] = [minus]0.67), (2) a diurnal cycle in the ratio of these two phases, and (3) a diurnal cycle in the ratio of organic gaseous Br to Cl. Organic gaseous Br and Cl were correlated (r[sup 2] = 0.67) indicating a common, possibly marine, source. 9 refs., 6 figs.
