ABSTRACT

The present study reports for the first time the occurrence of selected pharmaceuticals and personal care products (PPCPs) in the shallow aquifer underlying the Kraków city. Urban groundwater samples were gathered from 11 wells, which can serve as the emergency water supply wells. Liquid chromatography with tandem mass spectrometry method with the previous pre-concentration of samples using an SPE technique was applied for the determination of the PPCPs selected. There were quantified concentrations of PPCPs from the groups of estrogens (17-α-ethinylestradiol (EE2), 2.6–18.7 ng/L), non-steroidal anti-inflammatory drugs (ketoprofen, 59.5 ng/L in 1 sample), and antimicrobial preservatives used in cosmetic production (methylparaben up to 91.5 ng/L). Triclosan was observed in all analysed water samples in concentrations above the limit of detection. The presence of the PPCPs in the shallow aquifer is an evidence that the sewer network system under the city leaks and then pollutes the urban groundwater.

摘要

本研究首次报告了克拉科夫市下浅层含水层中特定药物和个人护理产品 (PPCP) 的出现。城市地下水样本采集自11口井，可作为应急供水井。液相色谱串联质谱法和先前使用 SPE 技术预浓缩样品的方法用于测定所选的 PPCP。对来自雌激素组（17-α-炔雌醇 (EE2)，2.6-18.7 ng/L）、非甾体抗炎药（酮洛芬，1 个样品中 59.5 ng/L）和抗微生物药物组的 PPCP 进行定量浓度化妆品生产中使用的防腐剂（对羟基苯甲酸甲酯高达 91.5 ng/L）。在所有分析的水样中都观察到三氯生的浓度高于检测限。
