Abstract A steady increase in the consumption of pharmaceuticals and personal-care products worldwide is increasing their occurrence in the biosphere. The current study describes the abundance of 42 selected emerging organic contaminants (EOCs), including human and veterinary antibiotics, UV-filters and analgesics in the groundwater of the urban aquifer of Zaragoza (Spain), which is affected by intensive exploitation of shallow geothermal resources. The presence of groundwater heat pump systems in the aquifer studied offered the opportunity to study the occurrence of EOCs in relation to groundwater temperature and other physicochemical effects derived from this technology. Analysis of the data obtained allowed us to identify statistically significant relationships between the presence of EOCs and temperature, as well as other physicochemical and geochemical properties of groundwater. The results obtained suggest that temperature is a minor factor controlling the degradation of the organic compounds analysed compared to the oxygen input from groundwater heat pump systems which is possibly increasing the aerobic redox conditions, thus preventing the degradation of organic pollutants. Intensive use of shallow geothermal resources therefore seems to contribute in the prevalence of such compounds in the aquifer close to geothermal systems.

萨拉戈萨（西班牙）城市含水层中药物和个人护理产品的存在及其与浅层地热能密集开采的关系

摘要 全球药品和个人护理产品消费量的稳步增长正在增加它们在生物圈中的发生率。目前的研究描述了萨拉戈萨（西班牙）城市含水层地下水中 42 种选定的新兴有机污染物 (EOC) 的丰度，包括人类和兽用抗生素、紫外线过滤剂和镇痛剂，该地区受到浅层地热资源的密集开采的影响. 研究的含水层中地下水热泵系统的存在为研究与地下水温度和该技术衍生的其他物理化学效应相关的 EOC 的发生提供了机会。对获得的数据的分析使我们能够确定 EOC 的存在与温度之间的统计显着关系，以及地下水的其他物理化学和地球化学性质。获得的结果表明，与地下水热泵系统的氧气输入相比，温度是控制所分析有机化合物降解的次要因素，这可能会增加有氧氧化还原条件，从而防止有机污染物的降解。因此，浅层地热资源的密集使用似乎有助于此类化合物在靠近地热系统的含水层中的流行。从而防止有机污染物的降解。因此，浅层地热资源的密集使用似乎有助于此类化合物在靠近地热系统的含水层中的流行。从而防止有机污染物的降解。因此，浅层地热资源的密集使用似乎有助于此类化合物在靠近地热系统的含水层中的流行。
