  • 摘要: 抗生素作为一类新污染物,对环境安全和人类健康构成潜在威胁。本研究采用固相萃取-高效液相色谱-三重四极杆串联质谱技术系统分析白洋淀区域淀区核心区、入淀河流及其河湖过渡区沉积物中5类抗生素(包括喹诺酮类、大环内酯类、四环素类、磺胺类和β-内酰胺类抗生素),共87种抗生素的赋存特征,并采用风险商值法评估其生态风险。结果表明,抗生素在41个采样点中普遍检出,总浓度为1 043 ng·g-1(0.710~139 ng·g-1),其中喹诺酮类抗生素的浓度占比最高(80.6%),检出率为95.1%;在检出的抗生素中,以优先兽用抗生素为主(占比82.5%),其次为人用抗生素;在空间分布上,府河及其过渡区的污染最为严重,淀区核心区、孝义河及其过渡区、白沟引河及其过渡区的浓度水平依次降低;与前期研究相比,白洋淀沉积物中抗生素的浓度呈下降趋势;结合抗生素用途、空间分布以及不同抗生素浓度分布的相关性分析可知,白洋淀沉积物中的抗生素主要来源于污水处理厂、水产养殖与未经处理的居民生活废水;风险商结果表明,氧氟沙星、林可霉素和环丙沙星分别有92.7%、51.2%和14.6%的采样点中RQ>0.1,对水生生物具有较高的生态风险;联合生态风险数据显示,白洋淀区域处于中高风险水平(联合风险商值为0.193~22.5)。本研究结果有助于深入了解抗生素在白洋淀地区的时空分布与生态风险,为制定科学有效的抗生素污染防治管控措施提供数据支持。

摘要: 抗生素作为一类新污染物,对环境安全和人类健康构成潜在威胁。本研究采用固相萃取-高效液相色谱-三重四极杆串联质谱技术系统分析白洋淀区域淀区核心区、入淀河流及其河湖过渡区沉积物中5类抗生素(包括喹诺酮类、大环内酯类、四环素类、磺胺类和β-内酰胺类抗生素),共87种抗生素的赋存特征,并采用风险商值法评估其生态风险。结果表明,抗生素在41个采样点中普遍检出,总浓度为1 043 ng·g-1(0.710~139 ng·g-1),其中喹诺酮类抗生素的浓度占比最高(80.6%),检出率为95.1%;在检出的抗生素中,以优先兽用抗生素为主(占比82.5%),其次为人用抗生素;在空间分布上,府河及其过渡区的污染最为严重,淀区核心区、孝义河及其过渡区、白沟引河及其过渡区的浓度水平依次降低;与前期研究相比,白洋淀沉积物中抗生素的浓度呈下降趋势;结合抗生素用途、空间分布以及不同抗生素浓度分布的相关性分析可知,白洋淀沉积物中的抗生素主要来源于污水处理厂、水产养殖与未经处理的居民生活废水;风险商结果表明,氧氟沙星、林可霉素和环丙沙星分别有92.7%、51.2%和14.6%的采样点中RQ>0.1,对水生生物具有较高的生态风险;联合生态风险数据显示,白洋淀区域处于中高风险水平(联合风险商值为0.193~22.5)。本研究结果有助于深入了解抗生素在白洋淀地区的时空分布与生态风险,为制定科学有效的抗生素污染防治管控措施提供数据支持。
