Bouncier Particles at Night: Biogenic Secondary Organic Aerosol Chemistry and Sulfate Drive Diel Variations in the Aerosol Phase in a Mixed Forest.

Environ Sci Technol 2019 Apr 24. Epub 2019 Apr 24.

Department of Chemistry , Purdue University , West Lafayette , Indiana 47907 , United States.

Aerosol phase state is critical for quantifying aerosol effects on climate and air quality. However, significant challenges remain in our ability to predict and quantify phase state during its evolution in the atmosphere. Herein, we demonstrate that aerosol phase (liquid, semisolid, solid) exhibits a diel cycle in a mixed forest environment, oscillating between a viscous, semisolid phase state at night and liquid phase state with phase separation during the day.

Recent Trends in Stratospheric Chlorine From Very Short-Lived Substances.

J Geophys Res Atmos 2019 Feb 16;124(4):2318-2335. Epub 2019 Feb 16.

Norwegian Institute for Air Research Kjeller Norway.

Very short-lived substances (VSLS), including dichloromethane (CHCl), chloroform (CHCl), perchloroethylene (CCl), and 1,2-dichloroethane (CHCl), are a stratospheric chlorine source and therefore contribute to ozone depletion. We quantify stratospheric chlorine trends from these VSLS (VSLCl) using a chemical transport model and atmospheric measurements, including novel high-altitude aircraft data from the NASA VIRGAS (2015) and POSIDON (2016) missions. We estimate VSLCl increased from 69 (±14) parts per trillion (ppt) Cl in 2000 to 111 (±22) ppt Cl in 2017, with >80% delivered to the stratosphere through source gas injection, and the remainder from product gases.

Utility of atmospheric transport runs done backwards in time for source term estimation.

J Environ Radioact 2019 Jul 14;203:98-106. Epub 2019 Mar 14.

Pacific Northwest National Laboratory, 902 Battelle Blvd., Richland, WA, 99354, USA. Electronic address:

One of the difficulties encountered in source-term analyses for airborne contaminants is the large computational effort required to predict air concentrations for all possible release scenarios. In some cases, analysts use atmospheric ATM runs with complex models done in the reverse-time direction because one ATM run done backwards in time for each sample can yield as much information as potentially hundreds or thousands of ATM runs done forwards in time. Unfortunately, the effective atmospheric dilution between the source and sampling locations differ depending on the time direction of the ATM run, with runs in the forward time direction being more realistic.

Determinants of airborne benzene evaporating from fresh crude oils released into seawater.

Mar Pollut Bull 2019 Mar 7;140:395-402. Epub 2019 Feb 7.

University of Bergen, Department of Global Public Health and Primary Care, Bergen, Norway.

Benzene, toluene, ethylbenzene, xylenes, naphthalene and n-hexane evaporating from a thin oil film was measured for 30 min in a small-scale test system at 2 and 13 °C and the impact of physicochemical properties on airborne benzene with time after bulk oil release was studied. Linear mixed-effects models for airborne benzene in three time periods; first 5, first 15 and last 15 min of sampling, indicated that benzene content in fresh oil, oil group (condensate/light crude oil) and pour point were significant determinants explaining 63-73% of the total variance in the outcome variables. Oils with a high pour point evaporated considerably slower than oils with a low pour point. Read More
