      abstract     = {The repeated use of a given pesticide may induce a
                      selection of the soil microbial population, resulting in a
                      rapid degradation of the respective xenobiotic. Patterns of
                      atrazine degradation (mineralization, formation of
                      metabolites and nonextractable residues (NER)) were
                      evaluated in two Brazilian soils with a history of atrazine
                      application. Results were compared with those obtained from
                      soils that had no agricultural use or herbicide application
                      history. (14)C-Atrazine mineralization in unsaturated
                      treated soils was high. By the 85th day of incubation,
                      $82\%$ of the applied (14)C-atrazine was mineralized in the
                      Rhodic Hapludox and $74\%$ in the Xanthic Haplustox.
                      Mineralization remained low in nontreated soils
                      $(<or=5.1\%).$ Incubation under slurry conditions enhanced
                      atrazine mineralization in the treated Xantic Haplustox and
                      surprisingly also in the nontreated Rhodic Hapludox (98 and
                      $83\%$ on the 85th day, respectively), whereas in the other
                      samples the evolved (14)CO(2) did not differ (p < 0.05) from
                      the unsaturated conditions. The water-extractable amount of
                      atrazine directly after (14)C-atrazine application was
                      higher in both Xanthic Haplustox samples (around $80\%$ of
                      applied atrazine) in comparison to the Rhodic Hapludox
                      samples (around $60\%).$ Extractable activity and the
                      formation of metabolites and NER varied among the studied
                      soils according to the atrazine application history rather
                      than the soil characteristics.},
