摘要
采集海河流域33个地表水源地样品,应用固相萃取、超高效液相色谱–串联三重四极杆质谱联用技术,对水源地水体中28种药物与个人护理品(PPCPs)进行检测,检测结果表明,海河流域水源地水体中有10种PPCPs检出,其检出率范围为6.1%~69.7%。将本研究区水源地水体中PPCPs含量与国外相关研究相比较,发现海河流域水源地水体中PPCPs处于中等偏低污染水平;应用风险商值模型对检出的PPCPs进行潜在风险评价,发现海河流域水源地表层水中选取的PPCPs除红霉素在YCSK、XHHSK、XFSK和XHSK中显示较低中等风险外,其余化合物均显示低风险。
Thirty-three surface water samples from drinking water source were collected in the Haihe River basin. Twenty-eight pharmaceutical and personal care products were extracted from surface water samples by solid phase extraction (SPE) and then analyzed by high-performance liquid chro-matography coupled with tandem mass spectrometry (UPLC-MS/MS). Ten of twenty-eight PPCPs were detected with detection rate ranged from 6.1% to 69.7%. Compared with the related research on drinking water source about PPCPs of the world, it was showed that the pollution level of PPCPs in the drinking water source of the Haihe River basin was moderate and low. An environmental risk assessment for the maximum detection concentration was undertaken using calculated risk quotients and indicated a low risk from 28 PPCPs in drinking water source except erythrocin in YCSK, XHHSK, XFSK and XHSK which showed medium risk.
