Determination of heavy metals in aerosols and deposition

Updated 2002-02-13

Total deposition sampling is performed at Ny-Ålesund to study atmospheric fluxes of heavy metals to the Arctic. In addition wet only deposition sampling is carried out with an automatic precipitation sampler. The samples are analysed at the home laboratory for tracer elements for seaspray components, earthcrust weathered material and anthropogenic elements by atomic absorption spectrometry and inductively coupled plasma-mass spectrometry (ICP-MS). One aim of our study is to distinguish element distribution between the dissolved and particulate phase. In addition to the element analyses the concentration of anions is determined by ionchromatography. In 1996 an automatically operating aerosol sampler was installed, which is combined with the automatic precipitation sampler to study element washout from aerosol particles via rain and snow.
