“…The concentrations of fenobucarb in water, soil, and the total residual amount in soil-water systems after 20 h were 0.317 mg kg -1 , 0.379 mg L -1 , and 16.4 µg, respectively. Next, the fenobucarb concentration decreased rapidly in both the water and soil phases, with more than 50% of the fenobucarb dissipating after 48 h. A similar observation was reported in a previous study (Alam et al, 2006). Fenobucarb was degraded by 18.7%, 66.9%, 72.5%, and 87.7% after 24, 48, 72, and 144 h, respectively.…”

“…The fenobucarb concentration in the soil samples was determined based on the fenobucarb dose applied for agriculture and its residue in the soil. Alam et al (2006) reported that the mean residue in paddy soil immediately after application on the rst day was 2.3 mg kg -1 when the fenobucarb dose was 1500 g a.i/ha (Alam et al, 2006). Therefore, a fenobucarb concentration of 5 mg kg -1 dw in the spiked soil was used in the present study and prepared according to previous studies (Trinh et al, 2017;Zhou and Zhu, 2007a;Zhou and Zhu, 2007b).…”

The presence of pH, dissolved organic carbon (DOC), and sodium dodecyl sulphate (SDS) in irrigation water for rice elds enhanced the release and biodegradation of fenobucarb in the soil-water system, contributing to the diminishing of fenobucarb and 2-sec-butylphenol in the soil and drain water. The fenobucarb-spiked soil was amended with pH 7, pH 9, 25 mg L − 1 DOC, and 1 critical micelle (2.4 g L − 1 ) SDS solutions, and the residual fenobucarb and 2-sec-butyl phenol were analysed in water and soil after each decomposition period. The disappearance of fenobucarb and the appearance of 2-sec-butylphenol were the result of biodegradation and hydrolysis, and these processes were in uenced by the presence in the order of pH 9, DOC, pH 7, and SDS. In the presence of SDS in the solution, the desorption and biodegradation processes simultaneously affected the degradation of fenobucarb in the soil. However, fenobucarb biodegradation was inhibited, probably because of the preferential utilisation of SDS by fenobucarb degraders.
