Epoxiconazole degradation from artificial wetland and forest buffer substrates under flooded conditions

► Epoxiconazole fate was studied under anoxic conditions in buffer zones substrates. ► Substrates included wetland sediments and plants, and forest soil and litter. ► Mineralization was low, but incomplete degradation led to unidentified metabolites. ► Plants favored both non-extractable and easily...

Description
Summary:► Epoxiconazole fate was studied under anoxic conditions in buffer zones substrates. ► Substrates included wetland sediments and plants, and forest soil and litter. ► Mineralization was low, but incomplete degradation led to unidentified metabolites. ► Plants favored both non-extractable and easily desorbable residues. ► A modified lag-phase degradation model fitted well data. The potential for 14C-epoxiconazole (EPX) degradation in wetland sediments, wetland plants, forest soil and litter was studied under flooded conditions. Mineralization was slow and low (
