- Subject of the guideline is a passive sampling system for dust, where particles are collected by sedimentation in the almost wind-free interior of the sampling device. The guideline describes the sampling procedure on different collection plates, the subsequent analysis of single particles with optical microscopy, and the application of further analytical methods. The guideline particularly supplies technical guidance for the characterisation of particles with geometrical equivalent diameters greater that 2,5 ?m, for the distinction of particle types (e.g. soil minerals, tyre abrasion, salts, pollen) and for the calculation of the particle mass concentratio
