A method of transferring suspended particulate matter (SPM) from the used filter of a beta-absorption mass monitor to a polycarbonate filter for subsequent PIXE analysis has been developed. The method allows determination of the relative elemental composition of SPM. It was demonstrated that PIXE analysis can detect S , Cl , Fe and Zn in SPM sampled over a one-hour period.

The elemental composition of suspended particulate matter (SPM) in the Barents Sea was studied based on the materials of the 68th cruise of the RV Akademik Mstislav Keldysh, August 2017, using ICP-MS and AAS methods. SPM of the sea surface layer is characterized by significant heterogeneity in the elemental composition, which is due to differences in the course of biogeochemical processes over the water area (for example, high differences in the level of primary production) and different compositions of terrigenous matter from the sources. Biophilic elements significantly enrich the SPM of the surface water layer and fluffy layer relative to the average composition of the earth's crust (the degree of enrichment of the surface SPM is higher than the fluffy layer).
