Particles were also analysed with a thermal-optical technique in order to determine their elemental and organic carbon content. In addition, meteorological sensors and real-time black carbon, ozone and carbon monoxide monitors were used. Particulate matter values were higher than background levels in continental Europe. A patent seasonal variation for organic and elemental carbon concentrations was observed, presumably related to stronger local primary emissions and to limited vertical dispersion. The higher levels were most likely a result of residential wood burning, since black carbon and carbon monoxide maximised during late evening hours in wintertime. Of the bulk of elutable organics, more than a half, on average, was present as acidic fraction. Alcohols, aliphatic and polyaromatic hydrocarbons represented together, more than 30% of the elutable mass, also showing a marked seasonal pattern with a minimum in summer and a maximum in winter. The winter increase was more evident for resinic acids, phytosterols, n-alkanoic acids and polycyclic aromatic hydrocarbons. %G English %L insu-00377224 %U https://insu.hal.science/insu-00377224 %~ INSU %~ UNIV-SAVOIE %~ UGA %~ CNRS %~ UNIV-GRENOBLE1 %~ INPG %~ IRSTEA %~ OSUG %~ LGGE %~ AGREENIUM %~ INRAE %~ USMB-COMUE
