Comparison of the Sampling Properties of the Bulk Deposition Samplers "Rotenkamp B" and "Miinden" A contribution to subproject BIATEX-2 R Zimmerling and U.

Gases and aerosols interfere with the selective sampling of sedimenting particles. In Germany, "Munden" bulk samplers have been widely applied to determine bulk depositions of nutrient ions (Balazs, 1991). So far, little is known about their sampling properties. In contrast, "Rotenkamp B" bulk samplers, which were developed for the measurement of depositions of S and N species, are well characterised with respect to the sampling of precipitation and the collection of gases and aerosols (
