      abstract     = {To assess the potential occurrence of accelerated herbicide
                      degradation in soils, the mineralization and persistence of
                      (14)C-labeled and nonlabeled atrazine was evaluated over 3
                      months in two soils from Belgium (BS, atrazine-treated
                      1973-2008; BC, nontreated) and two soils from Germany (CK,
                      atrazine-treated 1986-1989; CM, nontreated). Prior to the
                      experiment, accelerated solvent extraction of bulk field
                      soils revealed atrazine (8.3 and 15.2 μg kg(-1)) in BS and
                      CK soils and a number of metabolites directly after field
                      sampling, even in BC and CM soils without previous atrazine
                      treatment, by means of LC-MS/MS analyses. For atrazine
                      degradation studies, all soils were incubated under
                      different moisture conditions $(50\%$ maximum soil
                      water-holding capacity (WHC(max))/slurried conditions). At
                      the end of the incubation, the (14)C-atrazine mineralization
                      was high in BS soil (81 and $83\%)$ and also unexpectedly
                      high in BC soil (40 and $81\%),$ at $50\%$ WHC(max) and
                      slurried conditions, respectively. In CK soil, the
                      (14)C-atrazine mineralization was higher (10 and $6\%)$ than
                      in CM soil (4.7 and $2.7\%),$ but was not stimulated by
                      slurried conditions. The results revealed that atrazine
                      application history dramatically influences its degradation
                      and mineralization. For the incubation period, the amount of
                      extractable atrazine, composed of residues from freshly
                      applied atrazine and residues from former field
                      applications, remained significantly greater (statistical
                      significance = 99.5 and $99.95\%)$ for BS and CK soils,
                      respectively, than the amount of extractable atrazine in the
                      bulk field soils. This suggests that (i) mostly freshly
                      applied atrazine is accessible for a complex microbial
                      community, (ii) the applied atrazine is not completely
                      mineralized and remains extractable even in adapted soils,
                      and (iii) the microbial atrazine-mineralizing capacity
                      strongly depends on atrazine application history and appears
                      to be conserved on long time scales after the last
                      application.},
