Fig. 3. High performance liquid chromatography (HPLC) chromatograms for metobromuron and linuron showing abiotic controls and degradation by Absidia fusca and Botrytis cinerea. (A) metobromuron 3, retention time (RT): 3.67 min; (a) standard (100 mg/L), 3 = 100%; (b) abiotic control, 3 = 99%; (c) Absidia fusca NCS, 3 = 78%, main other peaks RT (min): 1.44–2.00–2.68–2.86; (d) Absidia fusca CS, 3 = 54%, main other peaks RT (min): 1.42–1.99–2.67–2.85; (e) Botrytis cinerea NCS, 3 = 10%, main other peaks RT (min): 1.50–1.99–2.69–2.86; (f) Botrytis cinerea CS, 3 = 10.5%, main other peaks RT (min): 1.49–2.03–2.40–2.70–2.88. (B) linuron 4, RT: 2.98 min; (a) standard (100 mg/L), 4 = 100%; (b) abiotic control, 4 = 43%; (c) Absidia fusca NCS, 4 = 34.5%, main other peaks RT (min): 1.38–2.31; (d) Absidia fusca CS, 4 = 20%, main other peaks RT (min): 1.39–2.36; (e) Botrytis cinerea NCS, 4 = 0.5%, main other peaks RT (min): 1.36–1.53–1.79–2.11–2.33–3.33; (f) Botrytis cinerea CS, 4 = 7%, main other peaks RT (min): 1.50–2.12–2.34–3.27. NCS, noncontaminated soil; CS, contaminated soil. Major peaks are underlined, secondary peaks are in italic type
