7.2 Analyses of Environmental Samples
Analysis in Environmental Organic Geochemistry dominantly focus on solid and
liquid samples (mainly soils, sediments, dust, sludge as well as ground, surface and
sewage water). For both sample types different preparation, extraction and fractionation procedures are needed as described in Chap. 3. Principally, water samples,
