      abstract     = {Soil drying and rewetting may alter the release and
                      availability of aged pesticide residues in soils. A
                      laboratory experiment was conducted to evaluate the
                      influence of soil drying and wetting on the release of
                      pesticide residues. Soil containing environmentally
                      long-term aged (9-17 years) (14) C-labeled residues of the
                      herbicides ethidimuron (ETD) and methabenzthiazuron (MBT)
                      and the fungicide anilazine (ANI) showed a significantly
                      higher release of (14) C activity in water extracts of
                      previously dried soil compared to constantly moistened soil
                      throughout all samples (ETD: p < 0.1, MBT and ANI: p <
                      0.01). The extracted (14) C activity accounted for $44\%$
                      (ETD), $15\%$ (MBT), and $20\%$ (ANI) of total residual (14)
                      C activity in the samples after 20 successive dry-wet
                      cycles, in contrast to $15\%$ (ETD), $5\%$ (MBT), and $6\%$
                      (ANI) in extracts of constantly moistened soils. In the
                      dry-wet soils, the dissolved organic carbon (DOC) content
                      correlated with the measured (14) C activity in the aqueous
                      liquids and indicated a potential association of DOC with
                      the pesticide molecules. Liquid chromatography MS/MS
                      analyses of the water extracts of dry-wet soils revealed ETD
                      and MBT in detectable amounts, accounting for 1.83 and
                      $0.01\%,$ respectively, of total applied water-extractable
                      parent compound per soil layer. These findings demonstrate a
                      potential remobilization of environmentally aged pesticide
                      residue fractions from soils due to abiotic stresses such as
                      wet-dry cycles.},
