International audience; Four sediment cores collected in the Seine River basin and dated between 1916 and 2003 were analyzed for lead concentrations and isotopic composition. In all four cores, the measured Pb concentration (up to 460 mg kg$^{-1}$) l

We have for the first time estimated volcanic emission of volatile metals for a large regional volcanic source showing permanent activity, namely the Indonesian Arc. We have done this by normalizing concentrations of metals ratios in volcanic plumes

We regularly collected volcanic gases and aerosols at Mt. Etna volcano over a long period (1991–1995) and measured their chemical composition by ICP-MS. Based on these data we present new evidence on the high volatility of both alkali and some heav

The volcanic flux of 210Po, a radiogenic and radioactive isotope belonging to the decay chain of 238U, has been quantified from its concentration in volcanic plumes and its mean residence time in the troposphere (Lambert et al., 1982). Measurements o

With the aim of testing the ability of 210 Po to be a tracer of volcanic aerosol plumes, we collected air samples during an oceanographic cruise around the Indonesian arc and measured the radioactivity of 210 Po. Owing to the atmospheric circulation
