      abstract     = {Veterinary antibiotics are unintentionally introduced into
                      the environmentand therefore found in ground and surface
                      water, soil andsediments, air, plants etc. They enter these
                      compartments mainly via application of manure or sewage
                      sludge to soils for fertilizing purposes or after
                      application in aquaculture, in form of the parent compound
                      or a transformation product. Generally, sorption,
                      transformation and transport determines the fate of these
                      organic contaminants in soil. Their wide-spread distribution
                      bears several risks, i. e. spreading of resistance genes or
                      occurrence in the foodchain. Long-term (60 days) batch
                      studies were conducted applying radiolabelled sulfadiazine
                      to samples from two agricultural soils to investigate the
                      sorption and sequestration behavior in the plow layers.
                      Sequential extractions at several time-steps served to
                      analyze the dynamics of both processes. A numerical
                      evaluation served to describe instantaneous sorption, the
                      dynamics of sorption and sequestration, and the formation of
                      non-extractable residues. Multiple extractions with the
                      harsh method questioned the concept of non-extractable
                      residues, since with each consecutive extraction step,
                      further sulfadiazine could be extracted. Analyzing the
                      liquid phase and the extracts from these batch experiments
                      with Radio-HPLC served to improve the understanding of the
                      transformation behavior in soils in different degrees of
                      (bio-)availability. Apart from the deduction of
                      rate-parameters for acompartment model, the resemblance of
                      the compositions in the liquid phases and the harsh extracts
                      was demonstrated. The formation of the up to six
                      transformation products showed distinct dynamics, either
                      spontaneous or with a time-lag. ...},
