      abstract     = {Biopurification systems, such as biofilters, are
                      biotechnological tools to prevent point sources of pesticide
                      pollution stemming from on-farm operations. For the
                      purification processes pesticide sorption and mineralization
                      and/or dissipation are essential and both largely depend on
                      the type of filling materials and the pesticide in use. In
                      this paper the mineralization and dissipation of three
                      contrasting 14C-labeled pesticides (bentazone, boscalid, and
                      pyrimethanil) were investigated in laboratory incubation
                      experiments using sandy soil, biochar produced from Pine
                      woodchips, and/or digestate obtained from anaerobic
                      digestion process using maize silage, chicken manure, beef
                      and pig urine as feedstock.The results indicate that the
                      addition of digestate increased pesticide mineralization,
                      whereby the mineralization was not proportional to the
                      digestate loads in the mixture, indicating a saturation
                      effect in the turnover rate of pesticides. This effect was
                      in correlation with the amount of water extractable DOC,
                      obtained from the digestate based mixtures. Mixing biochar
                      into the soil generally reduced total mineralization and led
                      to larger sorption/sequestration of the pesticides,
                      resulting in faster decrease of the extractable fraction.
                      Also the addition of biochar to the soil/digestate mixtures
                      reduced mineralization compared to the digestate alone
                      mixture but mineralization rates were still higher as for
                      the biochar/soil alone. In consequence, the addition of
                      biochar to the soil generally decreased pesticide
                      dissipation times and larger amounts of biochar led to high
                      amounts of non-extractable residues of pesticide in the
                      substrates. Among the mixtures tested, a mixture of
                      digestate $(5\%)$ and biochar $(5\%)$ gave optimal results
                      with respect to mineralization and simultaneous sorption for
                      all three pesticides},
