Abstract: The degradation of a chiral nonylphenol isomer, 4-(1-ethyl-1,4-dimethylpentyl)phenol (NP(112)), in two agricultural soils from Monheim and Dortmund, Germany has been studied. The degradation of NP(112) and the formation of a nitro-nonylphenol metabolite were determined by means of GC-MS analysis. The degradation followed bi-exponential order kinetics, with half-life of less than 5 days in both soils. The nitro-metabolite was found at different concentration levels in the two soils. The nitro-metabolite of NP(112) was more persistent than its parent compound. After 150 days about 13% of the initially applied NP(112) remained in the Monheim soil as its nitro-metabolite. Results of the E-screen assay revealed that the nitro-NP(112) has oestrogenic potency of 85% of that of NP(112). Furthermore, the results of chiral GC-MS analysis revealed that no chiral degradation of NP(112) occurred in this study.
