Article Synopsis
- The study reveals high levels of hydrochloric acid (HCl) and halogens (Cl, Br, and BrCl) in an industrial plume near the Great Salt Lake, Utah, highlighting a significant environmental concern.
- Complete oxygen depletion was linked to the production of halogen radicals, correlating with reported emissions from nearby facilities for chlorine and HCl, but bromine levels were estimated based on unreported inventory data.
- A photochemical model demonstrated that bromine radicals were the primary cause of rapid oxygen depletion, and including halogen emissions in environmental models indicated a 10%-25% increase in particulate matter in the Great Salt Lake Basin, exacerbating air quality problems in the region.
NO reactive uptake kinetics and chlorine activation on authentic biomass-burning aerosol.
Environ Sci Process Impacts
October 2019
We examined the reactive uptake of dinitrogen pentoxide (N2O5) to authentic biomass-burning aerosol (BBA) using a small chamber reservoir in combination with an entrained aerosol flow tube. BBA was generated from four different fuel types and the reactivity of N2O5 was probed from 30 to 70% relative humidity (RH). The N2O5 reactive uptake coefficient, γ(N2O5), depended upon RH, fuel type, and to a lesser degree on aerosol chloride mass fractions.

Biomass burning is a source of both particulate chloride and nitrogen oxides, two important precursors for the formation of nitryl chloride (ClNO), a source of atmospheric oxidants that is poorly prescribed in atmospheric models. We investigated the ability of biomass burning to produce NO(g) and ClNO(g) through nocturnal chemistry using authentic biomass-burning emissions in a smog chamber. There was a positive relationship between the amount of ClNO formed and the total amount of particulate chloride emitted and with the chloride fraction of nonrefractory particle mass.
