INFLUENCE OF WET STORAGE OF SPRUCE WOOD ON GROUNDWATER QUALITY - INVESTIGATIONS BY WATER-CHEMICAL METHODS, PYROLYSIS-FIELD IONIZATION MASS-SPECTROMETRY AND LUMINISCENT-BACTERIA BIOASSAY

For groundwater below a wet-storage location for spruce wood, water-ch emical analyses indicated a distinct pollution by inorganic and organi c compounds. Due to the high ammonium concentration this groundwater w as not suitable as drinking water. Using pyrolysis-field ionization ma ss spectrometry, a direct and fast molecular-chemical characterization of the organic constituents in the polluted groundwater was possible. No pretreatment except freeze-drying was required. The combination of water-chemical methods, analytical pyrolysis and bioassays allows to determine water quality and the organic constituents of dissolved orga nic matter with respect to toxicological properties.
