Black carbon or brown carbon? The nature of light-absorbing carbonaceous aerosols
Although the definition and measurement techniques for atmospheric "black carbon" ("BC") or "elemental carbon'' ("EC") have long been subjects of scientific controversy, the recent discovery ofExpand

Optical properties of humic-like substances (HULIS) in biomass-burning aerosols
We present here the optical properties of humic-like substances (HULIS) isolated from the fine fraction of biomass-burning aerosol collected in the Amazon basin during the LBA-SMOCC (Large scaleExpand

Levoglucosan levels at background sites in Europe for assessing the impact of biomass combustion on the European aerosol background
[1] Atmospheric levoglucosan has been determined as a proxy for "biomass smoke" in samples from six background stations on a west-east transect extending from the Atlantic (Azores) to theExpand

Inorganic, organic and macromolecular components of fine aerosol in different areas of Europe in relation to their water solubility
A chemical mass balance of fine aerosol (<1.5 μm AED) collected at three European sites was performed with reference to the water solubility of the different aerosol classes of components. TheExpand

Source apportionment of PM2.5 organic aerosol over Europe: Primary/secondary, natural/anthropogenic, and fossil/biogenic origin
On the basis of a 2-year comprehensive data set obtained within the CARBOSOL project, seasonal source apportionment of PM2.5 aerosol is attempted for five rural/remote sites in Europe. The approachExpand

Formation of secondary organic aerosols from isoprene and its gas-phase oxidation products through reaction with hydrogen peroxide
Aerosols produced over forests impair visibility and may affect climate by scattering and absorbing solar radiation and by serving as cloud condensation nuclei. Here, we introduce, to our knowledge,Expand

Atmospheric tar balls: Particles from biomass and biofuel burning
[1] “Tar balls” are amorphous, carbonaceous spherules that occur in the tropospheric aerosol as a result of biomass and biofuel burning. They form a distinct group of particles with diametersExpand

Polar organic compounds in rural PM 2.5 aerosols from K-puszta, Hungary, during a 2003 summer field campaign: Sources and diel variations
Abstract. In the present study, we examined PM2.5 continental rural background aerosols, which were collected during a summer field campaign at K-puszta, Hungary (4 June-10 July 2003), a mixedExpand

Isolation of water-soluble organic matter from atmospheric aerosol.
The development of a solid phase extraction (SPE) method is presented, which is capable of isolating approx. 60% of the water-soluble organic compounds from aerosol samples. The aqueous extracts ofExpand

Climatology of aerosol composition (organic versus inorganic) at nonurban sites on a west-east transect across Europe
in central Europe. Aerosols were analyzed for 210 Pb, inorganic ions, elemental (EC) and organic (OC) carbon, water soluble organic carbon (WSOC), macromolecular type (humic-like) organic substancesExpand
