Abstract
Androstenedione is a natural steroid hormone and endocrine disruptor. Batch and laboratory microcosm experiments and studies were conducted to investigate its adsorption and degradation in three soils. The Freundlichparameter Kf of androstenedione in the tested soils. Cattle manure dissolved organic matter (DOM) at 20 mg C·L−1 decreased androstenedione sorption in the three soils Degradation rate positively correlated with content clay and silt, while negatively with content of sand under same conditions. Soil moisture significantly affected the persistence of androstenedione in red soil and black soil, whereas there was no significant difference in alluvial soil. Androstenedione half-life increased, ranging from 2.04d to 17.33d under soil temperatures of 20°C,10°C, and freeze-thaw cycles between +10°C and−10°C. Androstenedione degradation was inhibited in black soil at -10°C. Androstenedione degradation significant affected by soil texture and environmental factors, manure DOM inhibitedandrostenedione sorption in three soils and can increase its transport to water sources.
