The fate of 3, 3′-dimethyl-4-methoxybenzophenone (methoxyphenone, NK-049) in paddy soils and its metabolism by soil microorganisms were investigated by using 14C-NK-049 labeled at carbonyl carbon. NK-049 disappeared rapidly under static (“anaerobic”) flooded conditions with half-life of about 10 days. Main products obtained were 3, 3′-dimethyl-4-hydroxybenzophenone (NK-049-OH) and 14CO2. Oxidized products of 3- or 3′-methyl group and reduced form at carbonyl group of NK-049 were also detected by thin layer chromatography (tlc). After 2 weeks of incubation, radioactivity of NK-049-OH reached 43.0 and 70.8% of the applied radioactivity in Mito soil and Konosu soil, respectively. Significant liberation of 14CO2 (55.0%) was observed in Konosu soil after 6 weeks of incubation, but it was only 0.7% in Mito soil. NK-049-OH was also degraded to yield almost the same amount of 14CO2 in Konosu soil as in the case of NK-049. Under shaking (“aerobic”) flooded conditions, 14CO2 was liberated from Konosu soil treated with 14C-NK-049 as under static conditions but little accumulation of NK-049-OH was observed. Microbial metabolites obtained by an isolated microorganism were common with those found in the soil except 3, 3′-dimethyl-4-methoxybenzhydrol.
