Indirect Determination of Integrated Chlorine and Bromine Concentration from Hydrocarbons in Barrow, Alaska

Abstract Details

2007, Master of Science (MS), Ohio University, Environmental Studies (Arts and Sciences).
This research investigates halogen chemistry near Barrow, Alaska at polar sunrise. Other researchers have previously shown that in the Arctic at polar sunrise, chlorine (Cl) and bromine (Br) are directly involved in hydrocarbon depletion, ozone depletion, and the conversion of gas-phase elemental mercury to reactive forms prone to local deposition. Concentrations of Br and Cl at polar sunrise have previously been inferred from hydrocarbon measurements at other Arctic sites. However, such studies have not been conducted at Barrow, a location suspected to have unusually high concentrations of bromine-susceptible hydrocarbons. In this work, hydrocarbon measurements at Barrow, Alaska during February – April 2005 are reported. This is the most comprehensive study hydrocarbon concentrations reported for this important polar research study site. Unusually high concentrations of bromine-susceptible hydrocarbons were not found. Time-integrated concentrations of Br and Cl were inferred from the hydrocarbon measurements. The slow and regular hydroxyl radical (OH) kinetics is discussed. Calculated air back trajectories are displayed with Geographical Information Systems layers to visualize air mass transport during sampling days.
