【摘要】 本文研究了汉江水相和沉积物中10种药品和个人护理品（PPCPs）的浓度分布、组成特征和污染来源;分析了汉江水相和沉积物中PPCPs含量的时空变化;结果表明,10种PPCPs物质的检出频率不同.枯水期和丰水期水样中∑PPCPs浓度分别为37.47—275.83 ng·L^-1和72.02—292.96 ng·L^-1,枯水期和丰水期沉积物样品中∑PPCPs浓度分别为24.71—85.12μg·kg^-1和3.35—171.84μg·kg^-1.水样中总浓度最高点出现在集家嘴的丰水期,且酮基布洛芬（KTP）的检出浓度最高,达250.59 ng·L-1.沉积物中浓度最高点出现在丹江口的丰水期,且以酮基布洛芬（KTP）和三氯卡班（TCC）为主.所有沉积物样品中各组分占比以酮基布洛芬（KTP）为主.采用风险商（RQ）法对汉江水相和沉积物中的10种PPCPs进行生态风险评估,结果表明,主要是酮基布洛芬（KTP）、三氯生（TCS）和三氯卡班（TCC）对细菌类、藻类、无脊椎动物和鱼类有明显不同的生态风险.汉江流域PPCPs的生态风险需引起关注.更多还原

【Abstract】 This study investigated the concentrations, distribution patterns and sources of pharmaceuticals and personal care products（ PPCPs） in the water and sediment samples of Hanjiang River; The temporal and spatial variations of the PPCPs concentrations were also analyzed. The results showed that the investigated 10 PPCPs had different detection rates. The total concentration of PPCPs in the water samples were 37.47—275.83 ng·L^-1 and 72.02—292.96 ng·L^-1 respectively in dry and wet season,and were 24. 71—85. 12 μg·kg^-1 and 3. 35—171. 84 μg·kg^-1 in the sedimentsamples respectively in dry and wet season. The highest total PPCPs concentration in the water sample was detected in Jijiazui in wet season,which showed the highest concentration of ketoprofen（ KTP）,up to 250.59 ng·L^-1. The highest concentration of total PPCPs in the sediment samples was detected in Danjiangkou in wet season in which Ketoprofen（ KTP） and triclocarban（ TCC） were the two dominant contaminants. In the sediment samples of both seasons,the dominant compound was ketoprofen（ KTP）. The risk quotient（ RQ） method was used for the ecological risk assessment of the detected PPCPs. The results suggested that primarily ketoprofen（ KTP）,triclosan（ TCS） and triclocarban（ TCC） posed significant ecological risks to bacteria,algae,invertebrate and fish at different levels. The ecological risks induced by PPCPs in Hanjiang River need more attention.更多还原
