Aerosol particulate matter is acknowledged to have effects on health and the environment and further investigation into the molecular characteristics of aerosols is necessary in order to fully understand the potential links between the molecular characteristics and the impacts that these particles have on health and the environment. Aerosols are often discussed with reference to their size because particles of different sizes can often be associated with different primary sources. This study presents a molecular-level chemical characterization of the water soluble organic matter fraction of 17 aerosol impactor samples representing 3 air mass influences (North American, North African, and marine) collected over the North Atlantic Ocean as part of the 2011 US GEOTRACES cruise via electrospray ionization Fourier transfor1n ion cyclotron resonance mass spectrometry. Aerosol water soluble organic matter of the different size fractions within each sample showed unique molecular-level chemical characteristics, with ...
