The proceedings of the seventh European symposium on the physico-chemical behaviour of atmospheric pollutants has recently been published by DG XII of the European Commission.

The symposium, held in Venice, Italy, on 2-4 October 1996, focused on the theme "The oxidizing capacity of the troposphere" - an issue which triggers off the most important global environmental problems related to anthropogenic perturbation of the atmosphere. The proceedings contain oral and poster papers presented at the symposium.

Priority was given in the symposium to studies performed in three main areas:

- Free radicals: Their role in tropospheric chemical reactions, measurement of their concentration in air and concentration trends;

- Tropospheric ozone formation processes: Role of biogenic and anthropogenic emissions, emission/deposition fluxes and modelling, atmospheric transport pathways, field measurements, the generalization of information from measurements for test sites to larger areas, laboratory experiments on ozone formation processes and on ozone forming potential of different classes of compounds;

- Aerosols, clouds and multiphase chemistry: Aerosol formation processes, anthropogenic modification of the population of cloud condensation nuclei, aerosol characterization, ice-phase in tropospheric clouds, multiphase chemistry of organic compounds, direct and indirect effects of aerosols on solar radiation in the troposphere.
