This paper shall give a short overview about analytical methods to test environmental mobilities and bioaccessibilities of trace metals in soils, sediments and airborne particulate matter, focussing upon essentials and toxics, as well as methods to minimize possible hazards. Merits and limitations of interpretations, like grain size effects and matrix effects, are outlined. It is based primarily on the experiences of the author and his comprehensive review, but contains still unpublished graphics. Multi-element determination techniques should be used to characterize the release of main elements and nutrients from the solid also.
