摘要: 针对环境持久性药物污染物(EPPPs)的污染问题,采用固相萃取-高效液相色谱/串联质谱法,调查分析了22种环境持久性药物污染物在天津地区水体和沉积物中的残留水平和分布特征。结果显示,水源地水样中有19种EPPPs的检出率为100%,质量浓度范围为0.21~0.69 μg·L-1,平均值为0.43 μg·L-1。地表水样中,除吉他霉素检出率为80%外,其余21种EPPPs的检出率均为100%,质量浓度范围为0.52~3.88 μg·L-1,平均值为1.60 μg·L-1。沉积物样中共检出11种EPPPs,检出率为100%,含量范围为0.04~1.10 μg·kg-1,平均值为0.52 μg·kg-1。其中蓟县于桥水库、蓟运河滨海新区段水样和独流减河滨海新区段沉积物样中检出的EPPPs残留水平较高,水体中环丙沙星、诺氟沙星与菲诺洛芬检出浓度较高,沉积物中则为吲哚美辛、水杨酸及氟苯尼考。对比国内外其他地区,天津地区水环境中EPPPs残留处于较高水平。

Abstract: Accroding to the pollution problem of environmental persistent pharmaceutical pollutants (EPPPs), the residual levels and distribution characteristics of 22 kinds of environmental persistent pharmaceutical drug contaminants in water and sediments in Tianjin were investigated by solid phase extraction-high-performance liquid chromatography/tandem mass spectrometry. The results display that the detection rate of 19 kinds of EPPPs was 100% in the water samples from sources, and the concentration range and average concentration were 0.21-0.69 and 0.43 μg·L-1, respectively. As shown in the surface water samples except for kitasamycin (80%), the detection rate for other 21 kinds of EPPPs was all 100%. Moreover, the concentration range of these EPPPs was from 0.52 to 3.88 μg·L-1 and the average concentration was 1.60 μg·L-1. Furthermore, 11 kinds of EPPPs were detected completely (100%) in the sediments and the concentration range and average concentration were 0.04-1.10 and 0.52 μg·kg-1. Among the above results, the EPPPs residue levels of water samples in the Yuqiao reservoir of Jixian county, Jiyunhe of New Binhai section and sediments in the Duliujian river basin of New Binhai section were the highest. Compared with other EPPPs, the concentrations of ciprofloxacin, norfloxacin, fenoprofen in the water and indomethacin, salicylic acid, florfenicol in sediments were high. In summary, EPPPs residues level of water in Tianjin was higher than other regions in China and other countries.
