| 摘要: | 应用固相萃取、超声萃取及高效液相色谱法对宁波市内河10个采样点的壬基酚、辛基酚和双酚A进行了检测. 结果表明: 宁波市内河水体及沉积物中均不同程度地检出了壬基酚和双酚A, 辛基酚的检出率约为50%; 壬基酚、辛基酚和双酚A在内河水体中的浓度最大值分别为4.516μg?L-1、0.384μg?L-1和1.594μg?L-1, 在沉积物(干重)中的含量最大值分别为0.811μg?g-1、0.139μg?g-1和0.223μg?g-1. 江北大河、宁大内河及护城河的水体与沉积物中的浓度值较高, 城湾水库、姚江及后西河相对较低; 水体及沉积物中3种酚类环境激素的浓度值夏季低于冬季, 水体和沉积物中的污染物浓度存在正相关关系. 宁波市内河受到3种酚类环境激素的污染, 对水生生物具有一定的生态风险. |
| Abstract: | Distributions of nonylphenol, octylphenol and bisphenol A in water columns and sediments at ten sample collecting stations in Ningbo Inner River were investigated using the method of high performance liquid chromatography coupled with ultrasonication extraction and solid phase extraction. It was found that NP and BPA are widely scattered in Ningbo Inner River, and the detection rates of both OP in water columns and sediments were about 50%. The highest concentrations of NP, OP and BPA were measured as 4.516 μg?L-1, 0.384 μg?L-1, 1.594 μg?L-1 in the river water samples, and 0.811 μg?g-1, 0.139 μg?g-1, 0.223 μg?g-1 in the sediments samples, respectively. The concentrations of the three phenolic endocrine disruptors were found to be higher in Jiangbei River, Ningda River and Hucheng River, and relatively lower in Chengwan Reservoir, Yao River and Houxi River, and with the higher concentration in winter than in summer. There was also a positive concentration correlation, although insignificant, among the three pollutants in water columns and sediments, The result shows that exposure to the phenolic environmental endocrine disruptors may risk ecological aquatic organisms in Ningbo Inner River |
