Abstract：
:The presence of organically bound halogens in precipitation was studied by first adsorbing organics on activated carbon and then analysing the chloride, bromide and iodide formed during combustion of the carbon. A standard instrument for the group parameter AOX (adsorbable organic halogens) was used for the combustion. The halides formed were trapped in an alkaline solution and analysed by capillary zone electrophoresis. The method described enabled determination of sub-ppb concentrations of the group parameters AOCl, AOBr and AOI (adsorbable organic chlorine, bromine and iodine, respectively). Analysis of rain and snow collected at different sites in Europe showed that organochlorines were responsible for the major part of the AOX content in all samples collected. Organically bound bromine was found in sub-ppb concentrations in all of the samples, whereas organic iodine was detected in only two of the samples.
