为了解汉江水体中壬基酚(NP)的行为，对汉江夏季、秋季和冬季的水样、悬浮物和沉积物样品进行了分析。水中壬基酚含量为23.2~187.6 ng/L，悬浮颗粒物中含量为6.8~190.8 ng/g L，沉积物中含量为25.4~932.0 ng/gdrywt。在沿河的所有基质中，都注意到了浓度增加的趋势。对于水和悬浮颗粒物，暖季浓度高于冷季浓度。随着水中温度的降低，悬浮颗粒相中壬基酚的百分含量从67%下降到28%。水和悬浮物的相关性较好(R2=0.63)。分配系数LogKp值为4.8。本研究没有观察到沉积物中浓度的季节变化。
In order to understand the behavior of nonylphenol (NP) in Han River, water, suspended particle and sediment samples were analyzed during summer, autumn and winter. Concentrations of nonylphenol in water ranged from 23.2 to 187.6 ng/l, in suspended particle from 6.8 to 190.8 ng/l and in sediment from 25.4 to 932.0 ng/gdrywt. An increasing trend in the concentration is noticed in all matrices along down the river. In case of water and suspended particle, concentrations were higher in warmer season than in colder season. Percentage of nonylphenol in the suspended particle phase decreased from 67% to 28% with decreasing temperature in water. A reasonable correlation (R2=0.63) was obtained for water and suspended particle. The partition coefficient LogKpis 4.8. No seasonal variation of the concentration in sediment is noticed in this study.
