摘要：

We have recently set up a new procedure for characterising the water soluble organic compounds (WSOC in fog water, for which information is still rather limited. Fog samples collected during the 1998-1999 fall-winter season in the Po Valley (Italy) were analysed following this procedure, which allows a quantitative determination of three main classes of organic compounds (neutral species, mono- and di-carboxylic acids, polycarboxylic acids), together accounting for ca. 85% of the total WSOC. This procedure also provides information on the main chemical characteristics of these three classes of compounds (functional groups, aliphatic vs. aromatic character, etc.). The enhanced chemical knowledge on fog/cloud chemical composition opens new scenarios as far as chemical and microphysical processes in clouds and fogs are concerned. (C) 2002 Elsevier Science B.V.
