Cape Verde, a West Africa Island country, is exposed to climate change effect. An effective way of reducing its poverty and achieving food security is to provide its agricultural sector with water. The purpose of this study is to monitor treated water quality to ensure that any pollutants are below the limits set to ensure the safety and sustainability of reuse because only 10% of its treated wastewater is reused. For the first time on Cape Verde islands, besides chemical quality, the occurrence of 11 pharmaceutical compounds (PhC) in the influent and effluent of two natural wastewater treatment plants (WWTPs) was monitored to assess the effectiveness of the treatment technologies and removal efficiencies of these pollutants. Of the 11 target PhC, nine were detected in influent samples within the ng·L⁻¹ to μg·L⁻¹ range. Lower concentrations were detected in one WWTP vs. the other. Nevertheless, the removal efficiencies for most compounds were similar in both WWTPs: within the ranges of 82–92% for beta-blockers, 48–99% for stimulants and 44–95% for nonsteroidal anti-inflammatories, while carbamazepine (anticonvulsant) concentrations increased in effluents. WWTPs produce water that meets water quality standards for irrigation if a properly designed and managed reusing system is adopted.

佛得角是西非岛国，深受气候变化影响。减少贫困和实现粮食安全的一个有效途径是为其农业部门提供水。本研究的目的是监测处理后的水质，以确保任何污染物都低于设定的限值，以确保再利用的安全性和可持续性，因为处理后的废水只有 10% 得到了再利用。在佛得角群岛，除了化学质量外，首次对两个天然废水处理厂（WWTP）进水和出水中 11 种药物化合物（PhC）的出现情况进行监测，以评估处理技术的有效性和去除效率。这些污染物。在 11 种目标 PhC 中，有 9 种在进水样品中检测到，其范围在 ng·L ^-1至 μg·L ^-1范围内。一个污水处理厂检测到的浓度低于另一个污水处理厂的浓度。尽管如此，两个污水处理厂中大多数化合物的去除效率相似：β-受体阻滞剂在 82-92% 范围内，兴奋剂在 48-99% 范围内，非甾体类抗炎药在 44-95% 范围内，而卡马西平（抗惊厥药）浓度在废水增加。如果采用适当设计和管理的回用系统，污水处理厂生产的水可以满足灌溉水质标准。
