The increased use of small molecular weight alcohols such as ethanol and potentially butanol isomers as biofuels has raised questions about the fate of these compounds in the environment once emitted. In order to address these questions, a method for

The global wet deposition flux of ethanol is estimated to be 2.4 ± 1.6 Tg/yr with a conservative range of 0.2–4.6 Tg/yr based upon analyses of 219 wet deposition samples collected at 12 locations globally. This estimate calculated by using observe

Rainwater and gas phase ethanol concentrations increased approximately fourfold between 2010 and 2017 in Wilmington, NC, USA. This 8-year study demonstrates that the gas phase and rainwater concentrations of ethanol have risen due to increased produc

The recent rapid increase in ethanol use as a biofuel and emission to the atmosphere may impact air quality and oxidizing capacity in the atmosphere. However, the global models show large uncertainties on sources of atmospheric ethanol. Concentration
